not sure, maybe one of the HCP folks could weigh in. You might try converting the lh.nii.gz to mgh file first. Should not make a difference, but it might On 9/14/16 10:24 AM, Sabin Khadka wrote: Doug- I did try mris_convert -o $SUBJECTS_DIR/FSsub/surf/lh.white $SUBJECTS_DIR/sub/REST/bold/001

Dear fellow FreeSurfer users, I can't get a subject to recon-all all the way through without crashing, regardless of the FS version used (deleted and started from scratch several times). It always fails with a Talairach transform fail error. Wondering if anybody else has experienced this issue

[Freesurfer] Getting combined bvals/bvecs

Hello freesurfer experts, I am trying to run tracula on subjects that have separate AP/PA direction DTI files. We combined the data into one using topup, and would now like to run tracula on the subject. The problem is, the combined file doesn't have a bvals/bvecs file. When I try to use the origi

Hi, Freesurfer Users. I tried searching for this question on the mailing list but couldn't get an answer. Hence, I am posting this here again. I ran the freesurfer analysis and got cortical thickness map for my group. I want to build an adjacency matrix by finding the correlation between the cort

Hello freesurfer experts, I am trying to register a functional volumetric image (.nii) into a surface (.gii) to produce a functional surface image (.gii), where each node of the image will contain a time-series. My purpose for doing this is to use freeview to visualize the time-series of each n

Hi Fred have you checked the transform to see if it actually failed? If not, you can just turn off the checking. If it did, you can manually correct it (or run without it) cheers Bruce On Wed, 14 Sep 2016, Uquillas, Federico D'Oleire wrote: > Dear fellow FreeSurfer users, > > I can't get a su

Hi Bruce, Thanks so much. So, how would I check if it actually failed or not? How would I turn off the checking? How would I manually correct it? Would running without it be essentially the same as turning off the checking (procedurally)? Best, Fred > On Sep 14, 2016, at 15:59, Bruce Fisch

Re: [Freesurfer] Getting combined bvals/bvecs

Hi Marissa - You have to specify as many b-values and gradient vectors as there are volumes in your DWI data file. This means that, if you combine the AP and PA volumes, you also have to concatenate the bvals from the two into one file, and do the same with the bvecs. Make sure that the order
