Thanks, Bruce. I am asking this because I believe that changing the processor or the operational system could change the processing.

[Freesurfer] RAM Replace
Dear all, I would like to know whether a RAM memory replacement in a Mac computer would change FreeSurfer 5.3 processing. I have a sample that was almost completely processed, but there are a few subjects whose acquisition are yet to be done. I would like know whether I could process such images after the RAM replacement without biasing the study. The change would be from a Markvision without ECC (error-correction code) to a Kingston with ECC.

Re: [Freesurfer] treatment effect compare to controls
Hi, yes, the first is to stack all the data into a single file (on your study average, usually that is fsaverage). The second steps smoothes the data. You can use different smoothing levels, depending on your data. Usually 10 or 15 is a good number. The data will automatically be taken from the sub1t1.long.tempsub1 etc directories (this is signaled by the --qdec-long flag. The qdec table needs to be in the longitudinal format, that means the first column is the subject id (sub1-t1) the second column the base name (tempsub1) column headers are fsid fsid-base …. usually the third column is time from baseline (in years), but can be any time variable that you want to use in the LME. There is an example of the longitudinal qdec table here: http://freesurfer.net/fswiki/LongitudinalTwoStageModel I'll probably add that to the lme page so it is easier to find.

[Freesurfer] Using -qcache command multiple times
Hello, I had a question about using the -qcache command for smoothing. Previously, the -qcache command was used on several subjects in my dataset, and since then, these subjects have undergone some manual edits (control points, edits to wm.mgz, etc.). Currently, I’d like to run the -qcache command on the entire group of subjects – do I need to delete any files created by the previous uses of -qcache first, or is it ok just to go ahead and run the command for all subjects?

[Freesurfer] Older version (5.0) on newer OSes
Hello everyone, I have a quick question about the feasibility of running FreeSurfer v5.0 on either RedHat/Centos 6.x or a newer Debian install. We want to run some new subjects but compare them to subjects run >5 yrs ago with FreeSurfer 5.0. Running all of the old subjects again in v5.3 is infeasible. I pulled down the Centos 5 binaries (just to try) but they segfault when running recon-all. I'd dedicate a machine to an older OS for compatibility, but we were hoping to use our NiPype pipeline, which works just fine with v 5.3 and is installed on the newer OSes. So - does anyone know if it's possible? TIA for any help.

Re: [Freesurfer] visualize subcortical areas in tksurfer?
Hi Daniel I wouldn't advise this - you will miss most of the activation unless it happens to be right next to where the surface runs adjacent to the structure of interest. For subcortical structures you are better off showing the results in slices. cheers Bruce On Mon, 23 Feb 2015, Yang, Daniel wrote: Hi Bruce, Thanks for the reply. My main question is how to best visualize subcortical activation in a figure.

Vol2surf samples a volume to an existig surface and none of the subcortical structures will be anywere near the cortical surface.
