correct mris_anatomical_stats syntax for cortical area
by Joakim Vinberg 27 May '11

27 May '11

Hi everybody, I just want to make sure I'm using the correct the correct syntax for running mris_anatomical_stats for examining cortical area. Based on the QDec Group Analysis page, my I was running the following command to examine cortical thickness: mris_anatomical_stats -l rh.test.label -t rh.thickness -b -f subject/stats/rh.test.stats subject rh To adjust this for cortical area, would I just replace the rh.thickness above with rh.area, or remove it entirely? Thanks in advance! Joakim

cerebellum atlas template
by Anthony Dick 27 May '11

27 May '11

Hello all, We are looking to develop a cerebellum atlas training set based on the Schmahmann et al (2000) parcellation so we can automatically segment the cerebellum based on this atlas. Does this exist already? I know Makris and colleagues had done something similar to this, but I am not sure if it has been developed for Freesurfer.

ris_fix_topology malloc error in FS5.1
by peter.molfese＠yale.edu 27 May '11

27 May '11

I was processing a particularly noisy participant which bombed out with the following error. Looking at the data, it shouldn't make it through the pipeline, but the error message seems more of a memory management issue. I've pasted it below, any thoughts? Freesurfer 5.1 (new build), Mac Pro Workstation with 40GB RAM, Mac OS X 10.6.7 Error Message: CORRECTING DEFECT 48 (vertices=60474, convex hull=11331) mris_fix_topology(23279) malloc: *** mmap(size=3887681536) failed (error code=12) *** error: can't allocate region *** set a breakpoint in malloc_error_break to debug Excessive topologic defect encountered: could not allocate 242979990 edges for retessellation Cannot allocate memory Darwin ella.haskins.yale.edu 10.7.0 Darwin Kernel Version 10.7.0: Sat Jan 29 15:16:10 PST 2011; root:xnu-1504.9.37~1/RELEASE_X86_64 x86_64 recon-all -s sn3086 exited with ERRORS at Thu May 26 22:47:37 EDT 2011 For more details, see the log file /zappa/freesurfer/PID/sn3086/scripts/recon-all.log To report a problem, see http://surfer.nmr.mgh.harvard.edu/fswiki/BugReporting

Freesurfer 5.1 - ERROR: talairach_afd
by Yiyu Chou 26 May '11

26 May '11

Dear Freesurfer Users, I tried the freesurfer 5.1 using command "recon-all -i xxx -s xxx -all" but I got an error message that didn't happen with version 5.0 on the same subject. "ERROR: talairach_afd: Talairach Transform: transforms/talairach.xfm ***FAILED***" Is it normal ? YY

Re: [Freesurfer] I/O performance mitigation

Hi David, I'm surprised you didn't have to do this in the past. We always space our jobs out.

Beginner question
by David Grayson 26 May '11

26 May '11

Hey folks, I am totally new to freesurfer, so please forgive me… I am trying to open up an atlas in freesurfer that is in 4dfp.ifh format (or nii, if you like). Can anyone tell me how? Otherwise, I could try to reconstruct it straight from the T1 anatomical run, but when I try the following command, taken from the tutorial recon-all -i Scan_0002_Img_0160_MR.1.3.12.2.1107.5.2.32.35139.2011042716283971836201295 -subject 106382 –all I get errors at the nu_correct step, and it terminates. And I am running these commands in NX, if that makes any difference Thank you in advance for your help! David

FreesurferEnv and matlab directory creation
by Peter J. Molfese 26 May '11

26 May '11

In the Mac version of Freesurfer, the FreeSurferEnv.sh script creates a matlab folder at ~/matlab. Can I change this location for running freesurfer on a grid (either Sun Grid Engine or Apple XGrid) where I won't always have access to a user folder? For instance, Xgrid runs jobs as an unprivileged user in a private directory (e.g. /private/var/xgrid/agent/tasks/TGSBflaF/working). Currently when I submit a job which sets up the freesurfer environment by calling the setup file and then a which to verify the environment is correct. The output shows that it executed the script and can now locate recon-all in /usr/local/freesurfer. But then I get a series of errors or warnings about matlab directory creation. Can I ignore these or silence them? Script: #!/bin/bash #setup Freesurfer export FREESURFER_HOME=/usr/local/freesurfer . $FREESURFER_HOME/SetUpFreeSurfer.sh which recon-all Output: INFO: /var/empty/matlab/startup.m does not exist ... creating /usr/local/freesurfer/bin/recon-all mkdir: /var/empty/matlab: Permission denied touch: /var/empty/matlab/startup.m: No such file or directory /usr/local/freesurfer/FreeSurferEnv.sh: line 213: /var/empty/matlab/startup.m: No such file or directory /usr/local/freesurfer/FreeSurferEnv.sh: line 214: /var/empty/matlab/startup.m: No such file or directory /usr/local/freesurfer/FreeSurferEnv.sh: line 215: /var/empty/matlab/startup.m: No such file or directory /usr/local/freesurfer/FreeSurferEnv.sh: line 216: /var/empty/matlab/startup.m: No such file or directory /usr/local/freesurfer/FreeSurferEnv.sh: line 217: /var/empty/matlab/startup.m: No such file or directory /usr/local/freesurfer/FreeSurferEnv.sh: line 218: /var/empty/matlab/startup.m: No such file or directory /usr/local/freesurfer/FreeSurferEnv.sh: line 219: /var/empty/matlab/startup.m: No such file or directory /usr/local/freesurfer/FreeSurferEnv.sh: line 220: /var/empty/matlab/startup.m: No such file or directory /usr/local/freesurfer/FreeSurferEnv.sh: line 221: /var/empty/matlab/startup.m: No such file or directory /usr/local/freesurfer/FreeSurferEnv.sh: line 222: /var/empty/matlab/startup.m: No such file or directory /usr/local/freesurfer/FreeSurferEnv.sh: line 223: /var/empty/matlab/startup.m: No such file or directory /usr/local/freesurfer/FreeSurferEnv.sh: line 224: /var/empty/matlab/startup.m: No such file or directory /usr/local/freesurfer/FreeSurferEnv.sh: line 225: /var/empty/matlab/startup.m: No such file or directory /usr/local/freesurfer/FreeSurferEnv.sh: line 226: /var/empty/matlab/startup.m: No such file or directory /usr/local/freesurfer/FreeSurferEnv.sh: line 227: /var/empty/matlab/startup.m: No such file or directory /usr/local/freesurfer/FreeSurferEnv.sh: line 228: /var/empty/matlab/startup.m: No such file or directory /usr/local/freesurfer/FreeSurferEnv.sh: line 229: /var/empty/matlab/startup.m: No such file or directory grep: /var/empty/matlab/startup.m: No such file or directory grep: /var/empty/matlab/startup.m: No such file or directory grep: /var/empty/matlab/startup.m: No such file or directory Peter J.

Announcement: FreeSurfer gets social
by Martin Reuter 26 May '11

26 May '11

Hi everyone, FreeSurfer finally becomes more social! You can now 'like' us on Facebook: http://www.facebook.com/FreeSurferMRI (there is no option to hate us or express any more complex feelings, sorry ...) or follow us on Twitter: http://twitter.com/FreeSurferMRI to always be up to date. Additionally you can also reach our pages at http://freesurfer.net and the wiki at http://freesurfer.net/fswiki now isn't that easy to remember? You know how it is, you are on the road, for some reason google is not working (or you just don't want to let them know how often you look at our awesome but slightly old fashioned pages) and you just need to find out how to run your analysis .... freesurfer.net :-) The 'surfer.nmr.mgh.harvard.edu' links (in case they are hardwired in you brain by now) will of course continue to work. Cheers, your FreeSurfer Team

Repeated measures ANOVA with covariate
by Mayuresh K 26 May '11

26 May '11

Hi freesurfer experts, Is there a way to perform a repeated measures ANOVA with a between subjects factor (two groups)? I am interested in comparing cortical thickness differences between the matched scans between the two groups i.e. measures*group interaction. How would I setup this design in freesurfer? Thanks, Mayuresh
