    Hello and thanks for the very interesting toolbox.

    If it is possible, I would like to see a sample atlas of an EEG setting.
    It is possible to create an atlas exporting coordinates from, e.g. eeglab?

    Hi Simone,

    Thank you for your interest in Braph. For some sample atlases we provide, please check the following link:

    For your second question, in Braph you could import a brain atlas in .txt, .xlsx or .xml file. Therefore, you could import the atlas coordinates from any software by first exporting them to one of the above formats and then importing that file into Braph. Please note that in order for Braph to be able to read the brain atlas file it needs to be prepared in a particular way, as explained in the above link.

    I hope that this helps you. If you need any additional information please do not hesitate to contact me.

    Hello Mite and thank you very much for the info,

    I have another question:
    It is possible with Braph to statistically analyzed EEG data in a within subject design, like paired-sample t-test?

    Hi Simone,

    Currently in Braph we implemented only between group analysis in which the statistical significance is reported by non parametric permutation tests. The withing subject design is not implemented in the current version of Braph.

    hello all,

    The coordinates taken from eeglab are not compatible with the brain coordinate system in your toolbox!
    specifically, the nodes coordinates lie on the region outside the brain template.

    what can we do about this problem.

    thanks in advance!

    Hi Elizabeth,

    Which is the coordinate system used by eeglab?
    Since you are working with EEG, doesn’t it make sense that the coordinates of the electrodes are outside the brain, on the scalp?

    The brain atlas GUI in Braph is intended only for visualization purposes.
    If your nodes are outside the brain template, that won’t interfere with the graph theory analysis. If you want to generate a figure with your nodes, you can adjust the coordinates so that they are closer to the brain template.

    Best wishes,
