[Freesurfer] ROI from left to right hemi - cortical thickness

Dear all, I have a ROI on the left hemisphere and I'd like to extract cortical thickness values from the homologous region in the right hemisphere. For this I applied the interhemispheric registration process and got my ROI mapped into the right hemisphere in /subject/xhemi/label. However when I

[Freesurfer] Freeview scripting reference

Hi list, I am looking for a complete reference to scriptable commands for Freeview, comparable to what exists for tksurfer (e.g. http://surfer.nmr.mgh.harvard.edu/fswiki/TkSurferGuide/TkSurferScripting/TkSurferScriptingReference) Does this exist? Thanks! ___

Re: [Freesurfer] Freeview scripting reference

Hi Inge, Freeview does not support tcl scripting. It does have lots of command-line options that might fit your need. Run 'freeview -h will display a complete list of the available options. Best, Ruopeng On 6/29/12 7:16 AM, Inge Kasbohm Amlien wrote: Hi list, I am looking for a complete

[Freesurfer] surface vertex pairs; voxel coloring for tkmedit

Hi, In regard to the surface files, is it correct to say that the wm and pial vertices correspond to each other (e.g., wm vertex # 12345 corresponds to pial vertex # 12345 as the minimum distance between the two surfaces), and so have the same number of vertices? Also, I would like to

Re: [Freesurfer] surface vertex pairs; voxel coloring for tkmedit

Hi John they are guaranteed to have the same # of vertices, so the answer is kind of yes, but the thickness is not the distance between them, but rather the distance from the closest point (which might or might not be the same vertex). You can use mri_surf2vol to sample back into the volume

[Freesurfer] Glmfit subtraction between 2 individuals

Hi all, I am trying to visualize the surface map showing the Post Treatment - Pre Treatment cortical thickness in a single subject. The Post and Pre scans are processed like 2 separate subjects. I used the commands: mris_preproc --f

Hi Adam, use the paired method in the fsgd examples. doug On 06/29/2012 11:58 AM, Adam Nitenson wrote: Hi all, I am trying to visualize the surface map showing the Post Treatment - Pre Treatment cortical thickness in a single subject. The Post and Pre scans are processed like 2 separate

Re: [Freesurfer] Glmfit subtraction between 2 individuals

Hi Adam, if you use the longitudinal stream for it (it is designed for that stuff and will increase reliability), you will have the surfaces in the same space and can simply subtract the thickness files (mris_calc) and visualize on any one of them. Best, Martin On Fri, 2012-06-29 at 11:58

Hi Joost, the tp id cannot be the same as the base id: fsid fsid-base ISI_years Group Gender Age ICV 11298 11298 0 patient F 16 1441 11298_2 11298 1.83 patient F 17.92 1396 I am amazed that you were able to process it this way? So either call the first time point 11298_1 or call the base

[Freesurfer] Qdec Error (more/better info)

Hi everyone, I got the error I just mentioned. Terminal window says no contrasts specified. I am trying to use timepoint (1-4) as a discrete factor to look at thickness across time. I guess I will have to resort to longitudinal processing? Thanks for the help -Anson

[Freesurfer] can I run recon-all in parallel

Hi, I am new to freesurfer. It seems recon-all is the most time-consuming command. I tried to run it on a HPC cluster with MPI and got the error ERROR: it appears that recon-all is already running and re-run and the job stopped right away. Is the code even parallelized? I had no problem running
