Hi, sorry if it's a dumb question but from what I understand, the network we get from first level analysis is essentially Region to Region (ROI-to-ROI) matrix e.g. load resultsROI_Subject001_Condition001.mat

Are we able to get Region to voxel networks in a similar manner? I am asking because I am able to import these ROI-ROI matrices into python for ML. But I also want to try for Region to Voxel as suggested by a paper I read. 

If anyone could enlighten me, I'd really appreciate it! Thank you
