Hello, After I make edits to my aseg output in the longitudinal stream, do I just run the following command to recreate the final volumes: recon-long -autorecon2-noaseg -subjid <Subj_ID> I assume the -subjid is the name of the edited time point and <Subj_ID> is the name of the recreated volumes? Thank you, Tamara

Generating intermediate surfaces?
by Souheil Inati 22 Jan '17

22 Jan '17

Hi All, I would like to generate some surfaces a bit below the white surface (in the white matter) and at several locations between the white and pial surfaces. Having trouble finding enough on the wiki - I’m guessing it’s some combination of mris_make_surfaces and mris_inflate? Any help would be greatly appreciated. Thanks, Souheil

ROI with precise coordinates
by Lisa Delalande 20 Jan '17

20 Jan '17

Dear all, I would like to know how to make an ROI an FreeSurfer/QDEC with precise coordinates. More precisely, I want an ROI called IFC consisting of combined pars opercularis and pars triangularis and with a box of 10 x 10 x 10 mm size, centered at MNI coordinates 10,-15,-5. Does a command line exists for that ? It is possible without drawing the label ? Thanks in advance for your help, Best regards. And I wish you a Happy New Year 2017 ! Lisa

Question
by N Saf 20 Jan '17

20 Jan '17

Dear FreeSurfers, I have a question about aseg file. I load the aseg file of bert subject in itk-snap and read the volume for 17 and 53 label but it is a bit larger of the volume in bert stats file. I do the same for some of my subjects too and I see the same result .I don't know why it is like that ?would you please clear the reason for me.because I need to compare the FreeSurfer result and I should use of aseg file labels but I'm afraid the comparison I'm doing is not valid. Sincerely yours, Nazanin

Freesurfer 6.0rc and Cuda library version
by Parzer, Peter 20 Jan '17

20 Jan '17

Would it be possible for the developers to provide the *_cuda binaries linked to different version of CUDA, as for example is done for bedpostx_gpu by FSL? The *_cuda binaries distributed with Freesurfer 6.0 are linked to CUDA 5.0. It not possible to install such an old CUDA version on a current Linux System.
