    Dear Mite,
    I have just known about BRAPH software and I am very happy to have find it on the web !! It seems to be a wonderful tool.
    However, as Amma querie, I am a little bit concerned about EEG connectivity matrix . Indeed, in the EEG field, connectivity matrix are not calculated from correlation (pearson or others types) while it is the case in fMRI data …. so as Amma I have already calculated connectivity matrices using phase locking values (PLV).
    You have given on this forum informations about how to proceede with but unfortunately I am not familiar with Matlab so I do not know how to do when you say:
    1. Modify the input to the GUIfMRICohort ……
    2. Modify the fMRIGraphAnalysis ….
    What do you mean by modify ?? What should I do ??
    Many thanks,
    Note that I have posted the same message by reply to Amma but because I am not sur that you will have access to it. I prefere to send it directly as a new topic !!!

    Dear Mite,
    Thank you very much for your help. I have done the modification in my EEGgraphAnalysis.m and then tried the software.
    Unfortunately, I am encountering a bug as soon as I am uploading my subject ‘s adjacency matrix.mat file (82×82, just as my Brain Atlas file). The message is “The file is not a valid EEG Subjects file. Please load a valid MAT file”
    Could you please help me !!
