Hi list,
to trasform a MASK.label (created by tk surfer) from surface to volume is
correct to use:
1. mri_surf2surf to register the mask from fsaverage to subj space2.
mri_surf2vol to report the label (subj space) to volume (subj space)
Thanks.

I've got a very basic question related to group analysis. If I want run a

Thank you for the feedback. Our version of FS 5.3 is the centos4 build
(which works perfectly) so I downloaded the same when got a copy of dev

Hello freesurfer experts,
Do you have a recommended "optimal" T1 protocol on Bay 1 for cortical
reconstruction?
For the past couple years, we've been using the 'tf1_mgh_multiecho_1mm_iso"
protocol which has PAT = 2 and a TA = 6:02. ๔๔
I'm wondering if a faster option at the same resolution is no
I'm just following up on this e-mail. I have not heard anything yet.

Hi Jason
SMS/multi-band doesn't really help 3D sequences. I believe we have done
ipat=3 and it has been fine, but perhaps Andre (or someone else who has
gotten this type of data) can confirm?

Excellent, thank you! To do that, do I send an e-mail to the listserv with the

yea, can you post the log file of both the successful and failing runs?

Hello all,
I had a question regarding the program Tracula. I have two different DTI
sequences that I wish to run (b=900 and b=2000) but am unsure at which step I
am suppose to merge the two sequences together.
At this point, I have pre-processed each of the sequences separately using

Hi Elijah - Are the bvec/bval files located in the current directory from
where you are running trac-all? This is where it seems to be looking for
them:

Hi Marissa - If your bvecs/bvals files are in row format, you need to make
sure that you have the most recent update that supports this. It was a
feature that was added later on:

Hi Xiaofu - It's hard to tell but it looks like the brain mask (which
