Hello.  Way back when in an older version of FSL, I had been using “Two masks –symmetric” in probtrack to identify pathways common to the two masks (ie. only want paths that go through both masks).  Now that I’m using probtrackx, I just want to make sure that I’m picking the right options.  Do I just want to pick “multiple masks,” enter the masks 1 and 2 or do I need to run “single mask,” enter mask 1, and then enter mask 2 under waypoints masks?  Or is there something else I should be doing?  Thanks!
