Dear all, I am working on brain parcellation based on structural connectivity matrices. I ran FSL's probtrackx on an HCP subject, seeding from the WM/GM 32k surface to get the seedxseed connectivity matrix (matrix1) and I am struggling a little with the outputs of probtrackx and the use of the workbench for visualization. It would be great if I could have some answers to a few questions:
-I obtained a matrix1.dot file that I would like to be able to visualize using the connectome workbench. I tried running the probtrackx-dot-convert command (I used a metric file with all ones for all nodes as -row/col-surface.) but the converted file appears to be all zeros when I load it in the workbench. Maybe I'm using the wrong metric file? -Is there a way to keep knowledge of the different tracts evaluated from one seed point to another? I am getting an image that counts all the tracts that go through a voxel, but I would like to know how seed A is connected to seed B. I was told this information is kept in the 'matrix4' output, which apparently cannot be read at the moment. Thanks.
