Hi Doug, I'm running into a strange seg fault when trying to use mri_segstats (it's actually ocurring within mri_glmfit-sim, but I can reproduce it manually)
This is the line that fails (stripping the leading paths for readability): mri_segstats --seg cache.th20.pos.sig.ocn.mgh --exclude 0 --i concat_output.nii.gz --sum mri_glmfit-sim.junk.84357 --avgwf cache.th20.pos.y.ocn.dat With the log: $Id: mri_segstats.c,v 1.75.2.9 2013/02/16 00:09:33 greve Exp $ cwd cmdline mri_segstats --seg /Users/mwaskom/Studies/PUnCH/cache/punch-switch_control/fsaverage_group/_l1_contrast_decision_neg/_hemi_lh/glmfit/_glm_results/osgm/cache.th20.pos.sig.ocn.mgh --exclude 0 --i /Users/mwaskom/Studies/PUnCH/cache/punch-switch_control/fsaverage_group/_l1_contrast_decision_neg/_hemi_lh/glmfit/_glm_results/concat_output.nii.gz --sum mri_glmfit-sim.junk.84357 --avgwf cache.th20.pos.y.ocn.dat sysname Darwin hostname ben-octocore.stanford.edu machine i386 user mwaskom UseRobust 0 Loading /Users/mwaskom/Studies/PUnCH/cache/punch-switch_control/fsaverage_group/_l1_contrast_decision_neg/_hemi_lh/glmfit/_glm_results/osgm/cache.th20.pos.sig.ocn.mgh Loading /Users/mwaskom/Studies/PUnCH/cache/punch-switch_control/fsaverage_group/_l1_contrast_decision_neg/_hemi_lh/glmfit/_glm_results/concat_output.nii.gz Voxel Volume is 1 mm^3 Generating list of segmentation ids Found 5 segmentations Computing statistics for each segmentation 1 1 10934 10934.000 2 2 2409 2409.000 3 3 1620 1620.000 4 4 2044 2044.000 Reporting on 4 segmentations Computing spatial average of each frame 0 1 2 3Segmentation fault Intriguingly, it does not segfault if I remove the --avgwf parameter OR the --exclude 0 parameter. It does segfault if I use --avgwfvol instead of --avgwf I'm not too sure what's going on, I can otherwise read the segmentation file and --y file and do statistical operations on them, and I can write other files to the directory I'm testing this in. Here's my system info: FREESURFER_HOME: /usr/local/freesurfer/5.3.0 Build stamp: freesurfer-Darwin-snowleopard-i686-stable-pub-v5.3.0 Kernel info: Darwin 10.8.0 i386 Any thoughts? Michael
