Re: [Freesurfer] using different Freesurfer versions for cross-sectional & longitudinal processing

2019-12-17 Thread Greve, Douglas N.,Ph.D.
I think it should be ok in principle, though it might fail because the v6 long stream expects there to be certain files with certain names, and they might not be there with 5.1. On 12/16/2019 2:49 PM, Morgan Botdorf wrote: External Email - Use Caution Dear Freesurfer Experts, We have

Hi Marina yes, mri_vol2surf will sample volumes onto the surface. You will need to register them first (we typically use Doug Greve's bbregister for this). What preprocessing did you do? For cortical data we don't recommend smoothing in the volume - you are much better off sampling to the surf

Yes, use mri_vol2surf. Make sure to use --projfrac 0.5 to sample in the middle of cortex. Run it with --help to get examples. On 12/17/2019 11:16 AM, Marina Fernández wrote: External Email - Use Caution Dear experts, I’ve done the fMRI preprocessing and now I would like to convert each f

OK, I'm still at a loss. The one suspicious thing is that it only took a few min to run. So you have never looked at that volume? What is in the atlas? On 12/16/2019 3:42 PM, Boris Rauchmann wrote: External Email - Use Caution This is the log when I´m creating this file: Boriss-MacBook

External Email - Use Caution Dear experts, I’ve done the fMRI preprocessing and now I would like to convert each file (that contains 250 volumes) to surface. Is it correct to use the function mri_vol2surf? Should I use any specific flag because they are 4D files? What is the best
