Thanks, Doug. I'm not planning to use qdec. It's just that I used to generate the ?h.thickness_max10.fwhm10.fsaverage_510.mgh files (which are what we name the files after running the two commands) before I use mris_preproc and mri_glmfit. I also generally skip the "smooth" step in freesurfer tutorial since the files are smoothed in the first place.
Any suggestions? Cherry On Thu, Mar 28, 2013 at 12:53 PM, Douglas N Greve <gr...@nmr.mgh.harvard.edu > wrote: > > > Actually, #2 will not work.
