Source code of connectivity graph

[Francois]

Using the connectivity graph display outside of Brainstorm would be very complicated, as it is tightly integrated with the application and the database.
It would be much easier to save your results as connectivity files in the Brainstorm database, and use directly the visualization tools from there.

Compute some connectivity results with the same dimension as your own results with Brainstorm, then modify only the TF field in the .mat file.

The storage of the various fields is documented here:

PTE: How is the connectivity matrix stored?

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…

How the Corr matix is saved?

I calculate the correlation matrix by the way NxN. when I check the saved file content, I did not find a N*N matrix. instead of it, I find a variable TF , stored M * 1 matrix. My question, how you experts stored the correlation matrix? In which way? where the pvalue associated with Correlation matrix is stored? How the cohr and other connectivity metris store the results. I tried to do further analysis , so I ask such question. In fact, your software is user friendly and almost perfect. …
