The connectivity graphs are views of the underlying connectivity matrices, that are saved on the database. You can display these matrices with a wright-click > Display as image.
For accessing the connectivity matrix, see these forum posts:http://neuroimage.usc.edu/forums/showthread.php?1796-How-the-Corr-matix-is-saved
Hi Sebastian,
To get the connectivity matrix correctly formatted, you can do the following:
Read the file timefreq_connect…mat into the variable TfMat, or right-click > File > Export to Matlab > “TfMat”
R = bst_memory(‘GetConnectMatrix’, TfMat);
The matrix R is the connectivity matrix [signalsA x signalsB x Frequencies]
The frequency bins are described in the TfMat.Freqs: R(:,:,1) is frequency TfMat.Freqs(1)
For details on the algorithm, see directly the process function process_compress_sym…
