Hi Doug
I re-analyzed one of my subjects from the very beginning with -projfrac 0.2. But still, in mri_vol2surf, the projfrac is 0.5 (copied below). Could you please let me know what I'm doing wrong? Here is my command: preproc-sess -s $subj -per-run -nostc -fwhm 0 -projfrac 0.2 -surface fsaverage lhrh -fsd bold -d $dir/all_subjects -force Thanks Mona mri_vol2surf --mov /autofs/space/oprah_001/users/jvm27/looming/7T/all_subjects/inul_reunpack/bold/024/fmcpr.nii.gz --reg /autofs/space/oprah_001/users/jvm27/looming/7T/all_subjects/inul_reunpack/bold/024/register.dof6.lta --trgsubject fsaverage --interp trilin --projfrac 0.5 --hemi rh --o /autofs/space/oprah_001/users/jvm27/looming/7T/all_subjects/inul_reunpack/bold/024/fmcpr.sm0.fsaverage.rh.nii.gz --noreshape --cortex --surfreg sphere.reg srcvol = /autofs/space/oprah_001/users/jvm27/looming/7T/all_subjects/inul_reunpack/bold/024/fmcpr.nii.gz srcreg = /autofs/space/oprah_001/users/jvm27/looming/7T/all_subjects/inul_reunpack/bold/024/register.dof6.lta srcregold = 0 srcwarp unspecified surf = white hemi = rh trgsubject = fsaverage surfreg = sphere.reg ProjFrac = 0.5 thickness = thickness reshape = 0 interp = trilin float2int = round GetProjMax = 0 INFO: float2int code = 0 Done loading volume Input reg is LTA Zahra (Mona) Nasiriavanaki Postdoctoral Research Fellow Martinos Center for Biomedical Imaging Massachusetts General Hospital 149 13th Street, 149-2615 Charlestown, MA, USA, 02129 ________________________________ From: Nasiriavanaki, Zahra Sent: Friday, March 1, 2019 11:52:21 AM To: freesurfer@nmr.mgh.harvard.edu Subject: Re: [Freesurfer] projfrac question Yes, I found it. I should mention that, this log file is the result of today's preprocessing (-projfrac 0.2) which I did in a separate folder, with all the previous preprocessing files being deleted. As you see the -projfrac is still 0.5 !
