Questions related to Mapping
I wish to get suggestions on how to use it for lower grade students learning assessment and few examples will help me a lot.
I have some gridded data generated with Generic Mapping Tools. these data have .grd extension and are working fine with GMT and Mirone. Whenever I try to import these gridded data in QGIS, it location goes out side the global map area. Its size on the base map also exessively large. How to resolve this problem.
I need tutorial to analyze RNA Seq data in ubuntu Linux and R, and IGV.
I can't run the commands in Ubuntu Linux for alignment of data and mapping of reads. I need the tutorial for running commands in Ubuntu for merge, sort and index my data, and have to use Sam tools, Bam tools, and Bed tools., but I can't run the commands. And also need to RNA Seq data analyzing in R and IGV as well.
ENVI SARScape 5.1 looks a very useful tool for monsoon flood mapping using Sentinel-1 data, which is one of my research interests. I would be grateful if someone helps me to download and install ENVI SARScape 5.1 (for free if possible). Thank you in advance.
Hello, I have bam and fasta file with several genomes aligned to each other with mafft. I want for each read and genome to have 3 numbers : number of bases from which match genome, number of reads which don't match genome and whether there is indel (0 if not 1 if there is). How to do it properly?
Thank you in advance!
I have around 54K probe IDs from the platform HGU95AV2 of the Affymetrix. I tried bioMart package in R, but got less 1% of the probe IDs mapped. Is there any alternate to specifically map to the HGNC symbols?
Science has many unsatisfactory explanations about dreams. Has anyone used quantum field theory to explain dreams? Is there any relation between dream mapping and neuron electric field?
Hi everybody, thanks for reading me.
I have two different data sets, uneven in terms of number of species. I want to focus my article on Systematics. The first one has 20 plant DNA sequences, and the second set is a morphological matrix with 95 species (including those from the first dataset).
I haven't found good recent examples of publications with 2 phylogenies, a molecular one and a morphological one. Also, I haven't found articles where topologies have significant differences in terms of the number of OTUs.
Colleagues have advised me to just do a mapping of morphological characters on molecular phylogeny, but I don't want to "loose" all my morphological work by excluding many characters which are not worthy to be mapped.
What is the most suitable "publishing strategy"?
I am looking for research proposal topic in UAV , autonomous robotics & swarm robotics. I would like to have more open discussion about these fields.
I'm a newbie to using the QGIS mapping program and have no idea how to find the appropriate CRS for the NE Atlantic, or rather the Iceland-Faroes-UK section; even the Iceland-UK-Biscay-Iberia sector. It may require alternatives according to the specific area of focus, I assume.
Any help gratefully received.
I have 3 robots and I know the starts and end coordinate of each of them. For example for Robot 1 I have Xr1, Yr1 and Xr2,Yr2 coordinates pair , same for Robot2 and 3. I have lateral cameras so can obtain the visual information. I would like to get the robot-to-robot relative position over time. The camera update is every 0.5 seconds. How can I approach this problem and any possible solution? Is the Hidden Markov Model chains would be a good approach? OR semantic Mapping can be helpful?
Dear, I am done a landslide susceptibility zones. I want to validate it with RMSE. As mentioned I took 398 observations to do RMSE in R. My result is 1.01
Can I use the result?
How to derive data for calculation of Tolerance (TOL) and Variance Inflation Factor (VIF) for hazard mapping?
I have all the data regarding landslide susceptibility mapping, and I want to analyze the data by using the logistic regression model, but still, I have no idea how to process it.
Is the use of open source airborne geophysical data scientifically correct to make a research paper? Are these data accurate? Like data available in U.S. Geological Survey (USGS)?
This question came to my mind as a result of a problem that occurred in the presentation of the open source airborne geophysical data from U.S. Geological Survey by using Geosoft software, I do not know if it is really a problem or not, it is about the range of values appear in the grid properties and the displayed legend bar, as the range of values for the eU map is much larger than the actual range values of the eU channel in the database. What can I do to display the correct range of radiometric values?
I tried to solve this problem by setting the Maximum and the Minimum values while mapping the grid with these steps:
Grid and Image > Display > Grid > More > Maximum Value = 4.6, Minimum Value = 0
After that when displaying the legend bar and choosing post-end values, the maximum value becomes very large, and the minimum value becomes negative.
The actual max value is 4.6 ppm and the min is zero.
This problem also appears in the eTh map, where the actual range of values is from 13.2 ppm (The maximum value) to zero (The minimum value).
I want to make sure that, these steps are scientifically correct or not?
Hi, I would like to make a paf file without repeating the reads being mapped to the sequence, like the --no-split option in mashmap, but I can't seem to find it on minimap2 option. Anyone knows how?
I have a data set consisting of GPS based species locations and would like to use it for mapping Rangeland plant species distribution. I humbly request anyone with a clear protocol I can follow.
I came across these methods in articles of the Iranian authors is related to mineral prospectivity mapping with remote sensing; TOPSIS and VIKOR methods like AHP and Fuzzy Logic same as in Arcmap so when I asked an author of an article, how can I perform these methods he gave me answer that he used matlab.
I am looking for answers about this subject;
Fuzzy and AHP is already in ArcGIS but What can I do for TOPSIS and VIKOR methods in Matlab? and How to use Matlab for mapping?
And second question;
How can I develop a mineral prospectivity mapping method/model in which programming language?
I have to work with raster datasets I think.
I want to know is there any method for crop type mapping using hyperspectral sensors without samples?
As per datasheet of AD4111 I cannot make the interface mapping for AD4111 to FPGA If any helps come it will be good for my recent project.
Register mapping will be more helpful.

Hi all. I want to create mapped mesh ( same nodes on opposite sides mapped and aligned with each other) for different geometry on opposite surfaces of a cuboid in y direction (top and bottom surface are having different features ) as shown in two figures ? Any help will be appreciated. Thanks all.
I am working on a satellite mapping project of thermokarst lakes in Eastern Siberia. I have satellite images which span the early 1960s -2019 and daily meterological data (temp and precip) from 1900-2019.
I would like to know if there is any statistical correlation between changes in lake surface area and temperature and precipitaiton.
There is a trend of increasing temperature and precipitation since 1900 (Mann-Kendell test), but there is of course quite a lot of yearly varaibility. Anecdotally, there are several years of substantial lake area increase which are preceeded by years of above average temperature. Is there any way to consider evaporation rates as well?
Thank you so much in advance for any suggestions.
I am trying top prepare pseudogenome alignments from VCF file after mapping reads to reference genome. I yried to use python script for that but it does not work. I was wondering if anybidy here has bash script to prepare pseudogenome alignemnts.
I'm doing a project on bioinformatics. I was given reads from 8 animals from two populations (4 cows from a cold environment and 4 cows from a hot environment). I mapped these reads, run quality controls and called SNPs and annotated them using SnpEff eff.
Now I have an annotated VCF file with genes and their corresponding SNPs. I'm looking for an efficient method to identify genes that have an effect on adaptation to cold and hot environments. I tried running Gene Ontology with pantherdb, but I can't interpret the results very well.
I would appreciate any suggestions of how more established researchers approach this problem. Any suggestions for papers or reviews on methodologies are also very much appreciated.
I would need ideas and examples for suitable models or frameworks for mapping money flows within a region. Input-output analysis works at industry level, while I am searching for tools to map individual, focal firm level money flows, perhaps constructing a network map. It should assist in visualizing the degree of interconnectedness among the actors, as well as the volume of monetary transactions. So far the examples I've found have bee related to tourism & catering and construction business, nonetheless with less robust methodology. What would be the state of the art approach in doing such analysis?
I performed Raman mapping with a Thermofisher DXR spectrometer. How to export the mapping data? In addition, I would like to ask you some suggestions concerning the plotting: how to plot correctly this kind of data?
I want to do solution mapping from the previous iteration to the next iteration in the Abaqus. Is it possible to do with inbuilt functions?
This mapping should work for the old mesh in the previous iteration to the new mesh in the next iteration .
Only empirical studies can be included for conducting bibliometric analysis or review papers can also be added?
How can we map or analyse the real time flood inundation mapping?
Many hydrodynamic modelling needs validation . However, due to lack of data, it could not be more accurate/precise. If we could know the actual/real time flood map, it would be overwhelming and efficacious approach to validate the model which can be helpful for decision makers and disaster authorities.
I use some mind map applications, but lately, most of the applications charge a fee. Therefore, if you suggest free mind map and concept map applications that you know, I would really appreciate it.
I am currently working in mapping trace elements in a worldmap using RStudio, I am very interested in finding RStudio packages which allows me to use geological databases in a Martian geological map. I will appreciate it a lot if someone could tell me about any interesting RStudio packages for this purpose.
Thanks in advance,

I have built a task scheduling algorithm in MATLAB. I am currently working on task scheduling optimization in fog computing. I have created the physical components, logical components(application modules) and also mapped the modules to the physical devices in iFogSim. But how to actually run these modules and call the scheduling algorithm from MATLAB to iFogSim.
Any help is really appreciated.
How to perform sensitivity analysis for dam/reservoir site suitability mapping? if we have considered some parameters (i.e. elevation, slope, distance to the river, geology, geomorphology). So, by using AHP we have done overlay analysis in Arc GIS to develop a suitability map. However, if the dam or reservoir is not constructed, how we can validate the model/resulted maps.
I am currently doing research that finds the applicability of Landsat 8 satellite images for Soil Salinity Mapping.
01) In order to do that I generated a few soil salinity indexes based on a few methods such as NDSI, VSSI, etc.
02) As the second step, I generated the actual soil salinity map by collecting samples and interpolating that sample points.
Now I have a problem about what is the best way to find the correlation between 2 raster images?
Can I use Fishnet in ArcGis and generate points for each pixel and then use Microsoft Exel or Python to generate the correlation or are there any other methods to find that correlation?
Please be kind enough to enlighten me if You know any methods, thank you.
I am looking for software for Systems mapping and Causal loop diagrams. It would be wonderful if any of you with experience in this could share some information.
Have you used any? Any advice or feedback? Pros and cons?
Thanks in advance,
I'm working with genotype-by-sequencing data. I have output a VCF file with the SNP calls, but in order to perform analyses, like trait mapping, I need to have the SNPs listed out in ACTG format (i.e. with the distinct calls for each locus in each individual). I'm having trouble finding a method (preferably in R) to do this.
Hi, I am planning to probe the surface potential distribution at a contact junction between two kinds of materials. The kelvin probe force microscopy and AFM-IR microscope can probe the surface potential in the air. I was wondering if these techniques could still work in an aqueous sample? Or any other technique could be an alternative?
Have you investigated publications associated with COVID-19 host risk factors and immunopathogenesis related research?
We are all aware that SARS-CoV-2 infection and disease risk factors are complex, resulting in widely varying outcomes, ranging from asymptomatic to severe illness, and death. To be able to evaluate one's own risk related to COVID-19, multiple contributing factors must be considered, including the well known and frequently discussed risk factors of old age, obesity, diabetes, social circumstances, environmental circumstances, and other commonly described co-morbidities along with SARS-CoV-2 variant behaviors. However, the well known and openly discussed risk factors are insufficient to explain the widely varying outcomes of SARS-CoV-2 exposure. Therefore, in the commonly used public domain information sources, some information is missing concerning additional, lesser discussed, but potentially critically important risk factors. It is clear to me that there is no single factor that can determine any particular individual's risk, therefore more information is needed to aid in risk assessment. In no way is this information outcome deterministic, and only represents additional statistical factors to consider when assessing one's own risk to exposure to SARS-CoV-2.
Well, I recently started looking into some of this research, and I would like to share some research that I think could be very important, and ultimately shed some more light on COVID-19, human host immunopathogenesis, and risk. Some of these papers summarize and evaluate research, performed by others, on various host factors that may be additional indicators of SARS-CoV-2 infection and associated disease severity risk. I have included links to articles, preprints, and studies so that we all can be aware of established and up and coming research. All of these articles are open and freely available to the public. I have also included a link to the Wikipedia website on global blood type distribution as a general reference. Do you know your blood type?

Used gem 5 to execute irregular mesh topology. but unable to remove the links .
Can application mapping be performed in irregular noc using noxim simulator?
I am new in this field. I am doing metagenome analysis with shotgun reads. All reads are single ended. DNA was obtained from airways of human. I just want to find taxon abundances in the samples. Then I will predict the diversities and core microbes.
My mapping results are terrible. How can I handle bad mappings?? OR should I change the tools that I used the analysis?? Which tools are more accurate or sensitive for microbiome analysis?? I need any suggestions, please!
I followed this pipeline:

Is there any tool that can account for systematic literature reviews, systematic mapping reviews, along side other quantiative methodologies such as meta-analysis? like a tool that encompasses all the common research methodologies? and is web based too ?
For instance, there is Nvivo for SLRs..
I performed ATAC-seq and found a relatively large number of mitochondrial reads under certain conditions. Under other conditions, mitochondrial reads are 20-30% of mapped reads, whereas, in one condition, mitochondrial reads are 60% of mapped reads. Since all 4 replicates have the same results, it does not seem to be a problem in experimental performance.
Usually, ATAC-seq is analyzed after mitochondrial reads are removed, but if there are a lot of mitochondrial reads under certain conditions, could this cause a problem in the analysis?
Or does the difference in mitochondrial read have any biological significance? (like a number of mitochondria, function....)
Does anyone know of any published research that has similar issues?
All suggestions are welcome, thank you.
I have observed there is a similarity in the formulation of contraction mapping and the condition for a function to be called a Lipschitz function. I have also come across the statement that the smallest value of the constant in a contraction mapping is termed as the Lipschitz constant. Is there any other connection between the two that I am missing ?
For this Al-10%Si alloy, I have tried to get the as-cast EBSD IPF mapping with normal hand-polishing. But on electropolishing with 10% Perchloric acid-90% ethanol solution at 15V, 20V, 25V, 40V for 10-15secs each the sample surface is getting etched but not polished, i.e., there is a height difference between the eutectic Si particles and Al phase.
Hence, what solution would be a better replacement to get a reasonable EBSD mapping??
We want to estimate the canopy volume of trees by 3D mapping using the LiDAR sensors. Please suggest low-cost LiDAR sensors available in India for 3D mapping.
Dear all, I finished writing a manuscript on Forest Fire Mapping using GIS. I would like to send it for publication in a peer reviwed journal. Can anyone recommend which journal I can go for publishing the manuscript? Kindly don't suggest predatory journals.
I have the following two questions:
1) Is the set of all natural numbers uncountable or Cantor's diagonal method is incorrect?
Let’s rewrite all natural numbers in such a way that they all have infinite number of preceding 0s. So 1 can be rewritten as …0001.
Then all the numbers can be enumerated as follows:
1 - …0001
2 - …0002
Applying Cantor’s diagonal method (for simplicity let’s do it from right to left), a number that does not appear in enumeration can be constructed, thus proving that set of all natural numbers is uncountable.
It seems that there is an issue with Cantor’s proof, since it can generate new natural number that does not appear in enumeration, but it should belong to the natural numbers. It seems that the issue stems from the fact that this is an infinite sequence of numbers. Over the first n-steps Cantor’s method generate a new number that does not appear in the first n sequences, but it may appear later. Since the number of natural numbers is infinite, it will take an infinite amount of time to generate it or in other words it can never be generated.
2) Mapping natural numbers to [0,1) interval. Are the set of all natural numbers and the set of all real numbers in [0,1) interval equal in size?
Again, let’s rewrite all natural numbers in such a way that they all have infinite number of preceding 0s as above:
1 - …0001
2 - …0002
Now let’s map all real numbers from [0,1) interval to natural numbers in such a way that digit from decimal position n in real number is a digit with index n-1 of the corresponding natural number:
…0001 - 0.1000…
…0002 - 0.2000…
…000123456789 - 0.987654321000…
Note that this mapping is bidirectional, so every real number from [0,1) can be put in correspondence with one natural number and vice versa, meaning that both sets are equal in size.
Is there an error in the above's logic?
Would appreciate everyone's input.
Is there any standardized open format for storing mobile mapping data?
- Exteroiur and Interiour Orientation
Due to the huge amunt of data and single files, a format optimized for data transfer tasks would be useful as well.
Do you know such Formats?
There are notable supply chains related to traditional and regional products that are still untouched by contemporary progress in supply chain management. The basic problem in SCM for these products lie in the lack of a descriptive reference model to even initiate SC research. Although SC mapping is still in an early stage in terms of design, it has been applied to bring out visualization of processes as well as complete industry SCs. Hence a question has been raised seeking the compatibility of SC mapping approaches for solving SC visualization problem. Do other methods available produce better results in visualization when compared with SC mapping approaches?
Current consumption and production patterns are increasingly founded in global value chains (GVC). Typically, GVCs are structured in several tiers distributed across countries and including a wide set of activities (design, production, distribution, etc). Given the current situation of industrial development and energy transition, comprehensive assessments are required to understand how supply chains work and where they are located. In this sense, which are the most appropriate indicators for mapping supply chains? According to the high availability of trade data (e.g., from Comtrade database), could the trade performance indicators (e.g., relative trade balance or Balassa index) be suitable for identification of net exporters or importers of commodities within the supply chain under evaluation?
I would appreciate if anyone could shed light on these questions.
I am trying to implement path tracking for bounded Homotopy method in mapped variables (from infinite to finite). My path tracking does not reach desired point. What could be best way of implementing effect of variable mapping on jacobian and tangent computation inside prediction and correction loop with mapping and un-mapping?
Hello! I am looking for vegetation data and aerial images for a region of Costa Rica, possibly going as far back as 1998. I have gone through Landview and EarthExplorer but I'm so overwhelmed - half the time I get spotty data or partial images. I'm looking for a resolution of 15m or less. I understand older stuff won't have this resolution but to be honest, even though data from some satellites are supposed to have this resolution, the images show otherwise. I keep getting general advice from colleagues, but when it comes down to it, I can't find what I'm looking for, and I'm hesitant to pay for maps when I am not even sure they will be what I'm looking for. Thanks in advance.
