Dear all, I'm running freesurfer and I have a problem at the step one with a patient (recon-all -stage1 -subjid ...): before ending the step I found: MOTION CORRECTING/tmp/cor 2 mmc Minctracc: command not found ERROR mritoself failed ERROR mri_motion_correct Non-zero status Coul you help me? Thanks valentina

For the lh, there is no cerebellum and no skull, looks to be correct.

Problem with latest dev version (crashes correcting errors)
by Tim Jarvis 06 Feb '06

06 Feb '06

Gave the new dev version a spin with autorecon-all, couple of things... For the mri_ca_register step, it took a total of 791 minutes! Is this normal or could this be a hint as to things going wrong early in the pipeline? Also, the program eventually crashed during the error correction, below are the lines that seem like they may have had some effect: Anyone else experience this problem?

I used PACE online motion correction on Bay 3, and now I am trying to figure out how to retrieve the motion data: how much motion was there? Any and all help is much appreciated. Thanks Ed

segmentation fault (core dumped) error during autorecon2 step
by Renat Yakupov 03 Feb '06

03 Feb '06

Hi everybody, I am running freesurfer-Linux-rh9-dev20051003 version of FreeSurfer on Fedora Core 3. I installed it without a problem and I can successfully run autorecon1 step, However, when I attempt autorecon2 step, it exits with an error after about 8 hours of processing. Please see attached a text file of complete autorecon2 step output and please see below the last lines about the error: Editing WM with SubCort Seg Fri Feb 3 08:30:54 HST 2006 mri_edit_wm_with_aseg wm.mgz aseg.mgz wm.mgz Segmentation fault (core dumped) ERROR: mri_edit_wm_with_aseg with non-zero status Linux extra 2.6.9-1.667 #1 Tue Nov 2 14:41:25 EST 2004 i686 i686 i386 GNU/Linux recon-all exited with errors at Fri Feb 3 08:31:08 HST 2006 I ran it on two different subjects' data with the same outcome. The weird thing is that these two subjects' dataset were processed on another computer with the same version of FreeSurfer and Fedora Core, and there were no problems. The computer I am having problems on is a Dell OptiPlex GX620. Has anybody encountered anything like that? Any ideas what might cause it? Thank you. Regards, Renat.

uncorrected vs. corrected comparisions ???
by trinity＠nmr.mgh.harvard.edu 02 Feb '06

02 Feb '06

Hi - I have a question about the fixed effects and random effects analysis. Are the values from the averaged maps corrected or uncorrected? Also, which is better to use for a group comparision? Are there certain instances when one is better to use than the other? Thank you! Trinity

Problem with setting segmentation threshold values
by Goradia, Dhruman D 01 Feb '06

01 Feb '06

Hi, I am interested in changing the white matter low limit for the segmentation step. For this I typed the following in the command prompt: recon-all -subjid <subjectname> -autorecon2 -seg-wlo <low limit value> this gave me an error stating that it could not recognize -seg-wlo flag. I was wondering if there is a mistake in writing the command? I would also like to know if there is any default lower limit for gray matter threshold used my mri_segment? If so what is it and can it be changed? Thank you. Dhruman Dhruman D. Goradia Research Specialist Western Psychiatric Institute and Clinic 3811 O'Hara St Suit 431 Pittsburgh PA 15213.

newest dev question

31 Jan '06

Dear all, Is the latest January dev release compatible with the previous one (Oct 2005) with regards to surface-based measures? Are there any differences in the segmentation algorithms or in the implementation of these algorithms which might cause differences in the surface files?

Display of thickness measurement
by Antao Du 31 Jan '06

31 Jan '06

Hi, I am interested in measuring the cortical thickness in entorhinal cortex. I can display the thickness measurement by " tkmedit AD1232 brain.mgz lh.white " to look at the measurement in entorhinal region, but I don't know the boundary of entorhinal cortex by this way. Is there any way that I can only display the measurement of cortical thckness in the entorhinal cortex? Thanks, Antao
