Emily, mri_surf2surf should do what you need. Use the --help flag for description and examples. Nick On Fri, 2006-12-01 at 15:56 -0600, Emily Cooper wrote: > hi, > i'm trying to map the functional data from each of my subjects into a > common space on the surface. i have moved my volume funct

hi, i'm trying to map the functional data from each of my subjects into a common space on the surface. i have moved my volume functionals into icosahedron space for two subjects and then converted to a .asc text file but the text files show that the two datasets have a different number of nodes (1

Hi Akram, Can you copy one of these subjects to: /space/tensor/14/users/jenni/testdir and I will play with it and see what I can do - I have some scripts that might do something. Jenni On Fri, 1 Dec 2006, Akram Bakkour wrote: Hi, I'm running everything on thigpen. setenv SUBJECTS_DIR /sp

Hi Juergen, use the mri/aseg.mgz volume. And no thickness or surface area of hippo - just volume at the moment. cheers, Bruce On Fri, 1 Dec 2006, Juergen Haenggi wrote: Dear Freesurfer users I tried to compute the hippocampal volume with the following command: mri_label_volume but whic

Hi Bogdan, I may have missed the beginning of this conversation - so I'm not sure what the initial problem was - but I don't think that the recon-all stream creates any symbolic links, so everything you ran should be ok. Have you looked at the outputs, do they look ok? make_average_subject tri

RE: [Freesurfer] Morphometric indices of the hippocampus

Hi Juergen, If you ran recon-all -all, you should have a file called aseg.stats in your /stats directory. This will contain information (volume, intensity) from the automatic segmentation (aseg.mgz) for all the structures we label. There are no surfaces generated for the hippocampus, so there

Hi Doug, while trying to expand the volume of my virtual machine to be able to create symbolic links I started wondering if the way I preprocessed my data with recon_all might be affected somehow by the fact symbolic links were not supported (the data was located on a mounted drive). The only

Dear Freesurfer users I tried to compute the hippocampal volume with the following command: mri_label_volume but which is the most appropriate volume to label? Is there also an opportunity to measure thickness and surface area of the hippocampi? I had run recon-all -all, but cannot find the
