Is it possible to convert EEG dataset into csv file and then analyse using R tool or weka??

actually i know R tool so first que is how to convert edf file into csv or textfile .
2 que is is it possible to analyse this eeg data in R tool,or weka?

What about the import of the coherence matrix into R? I've been trying to find some information outhere without success. I could use some help.

Usually it is better to import EEG data directly into R, MATLAB or Python from its native file.
For .edf files I found this utility with a quick Google search:

Following up on Michael's post:
Really, it is 'possible' to analyze EEG data in any software; most of the analysis is just basic math. However, there are open-source toolboxes in MATLAB and Python (e.g., EEGLAB, Fieldtrip, ERP PCA Toolkit, mne-python) that have already implemented most common tasks and will save you a lot of effort. R also has some stuff (e.g., I see an eegAnalysis package on CRAN) but I'm not sure how extensive it is.

I highly recommend the use of this page to download data:
Very easy to use. I wasn't able to get data from that page any other way. I hope it's usefull for someone in the future.

A very good free tool to read and convert EEG (and MEG) data is AnyWave : http://meg.univ-amu.fr/wiki/AnyWave

There is a comprehensive guide by Nienke Meulman ( https://www.nienkemeulman.nl/materials) that shows how you can import the raw EEG files into R. You save the end-product as .rdat files I believe, but if you really wanted to you could probably also export them to .csv.
On the same website is also a tutorial on how to analyze this data, if you were to use the event related potential method.
Can you help by adding an answer?

Hi,
I am totally new to the field of EEG signal analysis, but I am exploring it to see potential processing/analysis techniques to be designed and implemented on FPGA for onsite clinical decision support. So, I have raw EEG signal in edf format which I have successfully implemented into matlab and ran the following code to calculate the relative power (based on a code I found online). However, the results do not match some done by another professional in this area (very close, but does not match). Would anybody help me improve the code below to get more accurate results or suggest other venues. Note: if you advise me to go to EEGlab, please point me to the exact steps to do there. 
Thanks in advance!
Any help highly appreciated!
