[Freesurfer] func2roi registration flag

2009-08-28 Thread Garth Coombs
Hi, We ran a data set through fslregistration, did our analyses, and then ran everyone through bbregister. We now want to do a new func2roi analysis using the fslregistration (so that it is consistent with our previous analyses). Is there a way to know which registration file (register.dat
