Yes. Both the path and the naming of the group connectome data have changed. It should be placed in lead/connectomes/dMRI/ as you already noticed.
Maybe I don’t get you right, but if you just want to visualize the fibers from groupconnectome data in trackvis, I guess Andy might already have the trk files. In general, the conversion can be done by ea_ftr2trk, if the space is known.
