mri_fuse_segmentations error in longitudinal stream
by Sandra Preißler 10 Mar '16

10 Mar '16

Dear freesurfer experts, I am running freesurfer “freesurfer-Linux-centos7_x86_64-dev-20150728”. On a Linux terminal: “Linux cortical 3.16.6-2-default #1 SMP Mon Oct 20 13:47:22 UTC 2014 (feb42ea) x86_64 x86_64 x86_64 GNU/Linux” After normal processing of the data cross sectional. Followed by the creation of the within-subject template (DTprae_P01) I get an error message running the longitudinal command (-long). The command line I used was: recon-all -long DTprae_P01 DT_P01 -all The subject directory is: /mnt/bp01dat_castor/Studie158_Phantom_Bein/Daten/MRT The subprocess ending with the error and the error message were the following: mri_fuse_segmentations -a aseg.presurf.mgz -c aseg.auto_noCCseg.mgz -n norm.mgz DTprae_P01.long.DT_P01 DTprae_P01 DTpost_P01 aseg.fused.mgz mghRead(/mnt/bp01dat_castor/Studie158_Phantom_Bein/Daten/MRT/DTprae_P01/mri/aseg.presurf.mgz, -1): could not open file using aseg.presurf.mgz as aseg volume using aseg.auto_noCCseg.mgz as aseg no-CC-label volume using norm.mgz as norm volume reading /mnt/bp01dat_castor/Studie158_Phantom_Bein/Daten/MRT/DTprae_P01.long.DT_P01/mri/norm.mgz and processing 2 timepoints, writing to aseg.fused.mgz loading data for subject DTprae_P01 ... mri_fuse_segmentations: could not read input volume /mnt/bp01dat_castor/Studie158_Phantom_Bein/Daten/MRT/DTprae_P01/mri/aseg.presurf.mgz Linux cortical 3.16.6-2-default #1 SMP Mon Oct 20 13:47:22 UTC 2014 (feb42ea) x86_64 x86_64 x86_64 GNU/Linux recon-all -s DTprae_P01.long.DT_P01 exited with ERRORS at Tue Mar 8 17:52:40 CET 2016 I checked the folder (DTprae_P01/mri) and there is no data called aseg.presurf.mgz. in which step is this data produced? How can I fix this problem? I hope you could help me. Kind regards, Sandra

Re: [Freesurfer] System crash by extremely much generated output v6 beta

Hi, I'm using a MacPro with 32 GByte RAM. The output of FreeSurfer is written to a disk with 1.5 TByte free space. At the time I ran into trouble the free disk space was about 11 GByte. When I wanted to inspect the progress after a few hours I noticed that the disk has ran out of space. I couldn't do anything but restarting the MacPro. Then the disk space was again about 11 GByte. So I reran the subject with recon-all -autorecon2 -autorecon3 and it happened again. Inspecting the log files I noticed that both times the problem occurred at exactly the same stage in the pipeline: mris-topo-fixer.

Re: [Freesurfer] Using external software to perform brain extraction, multiple T1s
by Chris Adamson 09 Mar '16

09 Mar '16

There was a post in 2015 from Richard Parker talking about using SPM brainmasks instead of the Freesurfer ones. I would like to do this but in some cases I have multiple T1s and I get the motioncor step to make a registered template. What steps do I need to perform to get a brainmask from one of the images into the template space created by motioncor? Apologies if this has already been asked.

Patch for ribbon.mgz failure
by Philip Deming 09 Mar '16

09 Mar '16

Hi Freesurfer team, I'm having an issue running -autorecon2. The program exits with errors because it is unable to create the ribbon.mgz file. According to the version 5.3 release notes, there is a patch available to fix this issue: Creation of the aseg.stats table fails when only running -autorecon1 or -autorecon2 because ribbon.mgz is not present. This has been fixed. Ask for a patch. How can I obtain the patch to fix the ribbon.mgz issue? Thanks, Phil

QDEC GUI or in-line command for Monte Carlo simulation?
by Karl Liu 08 Mar '16

08 Mar '16

Dear Freesurfer Experts: I would appreciate your help in clarifying one issue I have when applying Monte Carlo simulation to control for multiple comparisons. First, I did the correction via QDEC GUI. In the section of Monte Carlo Null-Z simulation, I set Threshold: 2.0 (0.01) and Sign: neg. This generates a "mc-z.neg.th20.sig.cluster.summary" file in each contrast folder. Later, I use the in-line: command mri_glmfit-sim instead. My input is: ri_glmfit-sim --glmdir Untitled --cwpvalthresh .05 --cache 2 neg --2spaces. This generates a "cache.th20.neg.sig.cluster.summary" file for each contrast. My question is : are these two summary files the same, one from QDEC GUI with name " mc-z..." and the other from in-line command with name "cache..."? My next question is: In QDEC GUI, when the simulation is finished, the GUI automatically illustrates the clusters/brain, based on a file named "mc-z.neg.th20.sig.cluster.mgh". But I doubted if this is post-correction results. What is the right way to view results after correction? Thank you very much. Karl

Message error in qdec analysis‏
by Lisa Delalande 08 Mar '16

08 Mar '16

Hello everyone, I've got some problems with qdec. I have .levels with more than 2 factors. For example a "grpe.levels" with three factors : children (enfant), adults (adultes) and nothing (rien). But if I want to exclude some subjects like children qdec doesn't work anymore (attachment : error message). Is that possible a .levels can not have more than two factors ? Or the problem came from anything else ? Thanks in advance for your help ! Best regards, Lisa
