Delft 3D-Flow produces NEFIS compliant history and map file output (*.dat files). The view capability of Delft 3D 's post processor is good but not as advanced as the specialized (scientific) visualization software like ParaView or VisIt. I want to view Delft 3D output in in ParaView but ParaView cannot open Delft 3D files directly.
One possible way is to convert Delft 3D output files to NetCDF (*.nc) files and then view it in ParaView as it can open *.nc files. I have even found a Matlab (see this https://oss.deltares.nl/web/delft3d/general/-/message_boards/view_message/1379779 and https://svn.oss.deltares.nl/repos/openearthtools/trunk/matlab/applications/delft3d/vs_trim2nc.m ) script as well to do the job however it failed with an error message ( Undefined function or variable 'filenameext' )
I do not know any other possible way to do the job. If someone would guide, suggest any other possibility or just comment, it will be highly appreciated.
Thanks and Regards

I have three datasets A,B and C. Each includes tens of thousands of chemical compounds. We know that A[1], the first compound in A, is similar to B[30] and both are similar to C[9999] and we call this compound NEO; A,B &C share a lot of such compounds. I wanna show A, B and C in such a way that each compound is a dot (Properties of the compound such as molecular weight can be used as 2D or 3D coordinates) and I also wanna show that they all share NEO and many more of such shared molecules and many more molecules that are only in A and not others, etc,etc.
A venn diagram would be the simplest way. But, can I make a venn diagram of the actual data, by showing each fragment as a dot and visualize the shared ones as overlapping?
Or a plot like the microarray having bins for compounds with certain properties and showing A,B,C with different colors (or A&C, A&B, B&C and A&B&C with colors)?
I also came across hiveplot but I'm not sure if that is a good option or not!
In reality A,B and C are datasets of compounds in natural products, FDA approved drugs and synthetic chemicals. I wanna visualize the distribution of these compounds, in other words which compounds are shared between these datasets.
Hi everybody
I want to save an image which constructed in Amira software in Microvisu3d format (.mv3d).Does anyone know if it is possible to save an image in this format? I only know Amira can open a file in this format but I don't know how I can save a file in this format.
I am always fascinated by the kind of diagrams that people publish in Cell, Nature, Science etc.. I want to get such a software that can help me in my research.
I have measured gene expression across eight time points, and multiple comparisons show many differences between the time points. I'd like to indicate these significant differences on my bar graph. Usually I would draw a line above the relevant bars and put * or ** above the line, but there are so many differences that the lines would become unwieldy and I feel my graph would just look too messy! Any suggestions? Should I just relegate the p values to a table?
I've tried to upload your visualization ontology : http://code.know-center.tugraz.at/static/ontology/visual-analytics.owl in Protégé 3.5, but I encountered a error. Did you check such a import?
Conference Paper Suggesting Visualisations for Published Data
I am searching for a good visualization tool for presenting my research results in a conference. Do you have any fancy tools in mind?
I use Paraview and have experimented with Mayavi for 3D visualisation (volume rendering, surface plots etc.). I find Paraview can be lacking in quality at times and Mayavi has been difficult to use - are there any alternatives people could recommend?
If you are willing to publicly share your experiences, I am very interested to hear your thoughts on the use of visual communication for scientific research. Specifically, I am interested in learning:
- your thoughts on the importance of visuals
- the type of software you use to create charts, graphs, schematics, illustrations
- how much time you spend creating these visuals
- your thoughts on the value of outside expertise to help you create your visuals
I am evaluating various Open Source tools for use in EE resarch. Few interesting ones would be Octave, SciLab, Python with Numpy and SciPy. Anyone care to share experiences, good or bad? Any other suggestions?
Two weeks ago, I attended two interesting presentations, one of a British SME (shoothill) on visualizing scientific data for the public (for example applying a technique known as Deep Zoom), the other of the Polytechnic University of Milan on using NASA world wind as a virtual globe in the area of environmental modeling. Both make me think of the role of visualizing research results depending on the target audience and about telling the right story to the right people. I have the feeling that in my filed (geospatial information science and Digital Earth), we still miss a strong commitment to such ideas and also education has to increase on related topics. Do you share this view / maybe also in other research areas? What are your experiences?
Hi there,
I'd love to hear your thoughts about what you think will be the next generation scientific visualization approach. Will it be interactive? More photo-realistic? What are the skills we need to learn today to keep up in the future?
