So why aren't they included in the 64-bit stable? How long would you expect these steps to take? Disclaimer: The materials in this e-mail are private and may contain Protected Health Information.

64 vs 32
by Sasha Wolosin 17 Nov '05

Dear all, I have run several subjects on a 64-bit machine using the stable release. I recently installed the 32-bit stable version on a 32-bit machine. I noticed that running stage1 on the 32-bit version took much longer than running stage1 on the 64-bit machine (several hours, actually). So I looked at the recon-all scripts for each version and I noticed that they were different. The 32-bit version includes the extra steps DoGCAReg, DoCANormalize, DoCAReg, and DoCALabel. Does anyone know why this is? Below are the stage1 lists for each version. Thanks, Sasha 32-bit version: case "-stage1": set DoMotionCor = 1; set DoTalairach = 1; set DoNuIntensityCor = 1; set DoNormalization = 1; set DoSkullStrip = 1; set DoSegmentation = 1; set DoGCAReg = 1; set DoCANormalize = 1; set DoCAReg = 1; set DoCALabel = 1; set DoFill = 1; set DoTessellate = 1; set SvInitOrigSurf = 1; set DoSmooth1 = 1; set DoInflate1 = 1; set SvInitInflated = 1; breaksw 64-bit version: case "-stage1": set DoMotionCor = 1; set DoTalairach = 1; set DoNuIntensityCor = 1; set DoNormalization = 1; set DoSkullStrip = 1; set DoSegmentation = 1; set DoFill = 1; set DoTessellate = 1; set SvInitOrigSurf = 1; set DoSmooth1 = 1; set DoInflate1 = 1; set SvInitInflated = 1; breaksw Disclaimer: The materials in this e-mail are private and may contain Protected Health Information.

Dear all, I have also noticed a discrepancy between the stable 32 and the stable 64. The FreeSurferEnv.csh files are quite different. Why is that? Are there any other differences?

mris_ca_label 32vs64
by Satrajit Ghosh 17 Nov '05

17 Nov '05

I'm noticing some discrepancies between the 64 bit and the 32 bit version of mris_ca_label. I've shown the output from the 64 bit version and the 32 bit version operating on the same subject. I'm using are the dev versions for centos from the download site. To note: 1. In the 64 bit version I get the following output during the process: GCSANclassify: could not find GCS for node 0! Numerical result out of range The 32 bit version does not generate this error on either on th 64 bit machine or a 32 bit machine. 2. The numerical values listed for changed and examined are different. This could well be the case if there was some random element being used.

tkmedit
by Sasha Wolosin 16 Nov '05

16 Nov '05

Dear all, My brains appear too bright after skull stripping, so I tried to fix this with the following command: tkmedit 2316_corffe brain -mm-main 0 255 But the --mm-main option did not have an effect unless I set the max to be lower than the actual max (which was about 170 in this case) The brightness/contrast gui in the tkmedit menu does not allow me to increase the max either. I am using the stable release for x86_64 machines. Thanks, Sasha Disclaimer: The materials in this e-mail are private and may contain Protected Health Information.

T1 volume problem
by Michele Perry 15 Nov '05

15 Nov '05

Hi, I am having problems with the dev version of Freesurfer. I realized after viewing the aseg that there was a skullstrip problem that I hadn't noticed when I checked the brain volume between -autorecon1 and -autorecon2. When I open brain.mgz and T1.mgz in tkmedit, they look identical (i.e. I can't see skull in the T1). Any idea what went wrong? Michele

so for the stable release should I run both mris_ca_label and mris_anatomical_stats? I'm not sure I understand how to use mris_anatomical_stats to get all the information- is it necessary to specify a surface file? Also, can I view the thickness map of an individual subject?
