Dear All,   I went thru the link suggested by Mr. Cedric.https://mail.nmr.mgh.harvard.edu/pipermail/freesurfer/2009-February/009600.html From that mail I understood how to create the label for multiple subjects. I already created a DLPFC for one individual. I want to know how to measure the

[Freesurfer] Problems with Saving Segmentation

Hello, I have troubles with saving my files, after I did some segmentation changes. I think this could be related to a problem, which I have, when I load the brainmask: libGL error: failed to load driver: nouveau libGL error: Try again with LIBGL_DEBUG=verbose for more details. This is

Dear Freesurfers, After running the first tests of freesurfer 5.2, I found a file named $hemi.w-g.pct.stats on the stats folder. The last column of the file is a SNR calculation, i found on the help manual, that is required to add --snr to perform this calculation. I'm interested to know how

Hi,  Sorry for the answer too late.  I tried the command to evaluate the RMS distance but I just get the difference between the 2 surfaces in terms of faces and vertices.  But I would compare my 2 surfaces by calculating the euler characteristic ( vertices-edges+ faces) .  Thank you so much

Hi everyone, I would just say you thank you for the help you give to Freesurfer users. I use Freesurfer for my school project and I ended yesterday. I didn't know anything about Linux before and before segmentation software of cortical surface. I don't think I would did an so great job

Hi Anupa you need to specify each input volume with -i if there are more than one. In your example you would need an inner loop of the form set inputs = () foreach vol (SZ*.nii) set input = ($inputs -i $vol) end recon-all $inputs ... cheers Bruce On Wed, 17 Apr 2013, Anupa AV wrote:

Hi Claudia that defect is bigger than more cortical surfaces so something is dramatically wrong. Did you check any of the outputs (wm.mgz, filled.mgz, lh.orig, etc...)? cheers Bruce On Thu, 18 Apr 2013, Claudia Dacquino wrote: Hi freesurfer,  my autorecon2-cp after ctrl pts edits exited

Thank you for your answer, Juan. Yes, I want a surface of the whole hippocampus and I thought I had just obtained that using freeview and adding all hippo-subfield files. That resulted in the screenshot I previously attached. I just do not know how I can save the resultant surface. After I

I agree with Bruce. You can use MRIread.m to read in the data. Regarding the other question: first you need to combine the posteriors of all the subfields into a single posterior for the whole hippocampus. You can do that like this: mri_concat posterior_fimbria.mgz posterior_CA1.mgz ... --sum
