Hello Xavier, If you open your dense connectome file using File: Open File, this entails loading ~30 GB of data into memory, which is slow and can indeed make wb_view crash.
Instead, it is generally preferable to use File: Open Location, and then enter the file’s URL into Custom: URL. Once that is done, clicking on a vertex or gray matter voxel should show the seed-based dense connectivity for that grayordinate. There are other options for on-the-fly computing and viewing the average functional connectivity for a user-selected ROI. I hope this helps.
