mris_anatomical_stats error
by yzhangd＠artsci.wustl.edu 16 Feb '10

16 Feb '10

Dear experts, i try to run the command mris_anatomical_stats to get GrayVol, ThickAvg, etc from the left cortex as following: mris_anatomical_stats -l lh.cortex.label -f nmr033_2/stats/lh.cortex.stats nmr033_2 lh so the output is like following and did not generate any stats file(lh.cortex.stats) : limiting computations to label lh.cortex.label. reading volume /windata/yuning/freesurfer/nmr033_2/mri/wm.mgz... reading input surface /windata/yuning/freesurfer/nmr033_2/surf/lh.white... reading input pial surface /windata/yuning/freesurfer/nmr033_2/surf/lh.pial... reading input white surface /windata/yuning/freesurfer/nmr033_2/surf/lh.white... /windata/yuning/freesurfer/nmr033_2/label/lh.cortex.label /windata/yuning/freesurfer/nmr033_2/label/lh.cortex.label Segmentation fault could anyone tell me what's wrong with it and what segmentaion fault is ? thanks a lot yuning

question abt mri_vol2surf....
by Ritobrato Datta 16 Feb '10

16 Feb '10

Hello All, I have a simple question. I have functional data (3 mm cubic voxels) from 20 subjects that I am using mri_vol2surf to resample on the fsaverage surface. I want to run qdec or mri_glmfit on these data. In order to do grp stats with functional data, what surface do I need to specify in the '--surf' flag ? Does it matter ? Thanks Ri

recon-all -s $subject -make all
by Alessandro D. Gagliardi 16 Feb '10

16 Feb '10

Hello FreeSurfers, recon-all -make is working now, but it's taking as long as it did the first time I ran it. I originally ran "recon-all -s cb -i CB_anat+org.BRIK -i CB_anat2+orig.BRIK -all" (for example) back in May and haven't messed with the results except for generating some label files with mri_annotation2label. I deleted the original BRIKs, but I don't see why that would matter in this case since the orig.mgz files are still there. Is it taking so long because so much has changed between 4.3 and 4.5, or is something wrong? Thanks, Alessandro D. Gagliardi Ph.D. Candidate Integrative Neuroscience Program Rutgers University Mind Brain Analysis adfgagliardi(a)gmail.com P.S. To generate a2009s annotations files for fsaverage, do I just run "recon-all -s fsaverage -make all"?

Hi all Could anyone help me with extracting the wmparc volume stats in accordance with Destrieux atlas? As it stands now the segmentations corresponding to whitematter beneath Destrieux 2009 parcellations are returned empty when called for Many thanks Lena \_________________________________ Lena Palaniyappan Clinical Lecturer & Honorary StR | Division of Psychiatry ( University of Nottingham) South Block 'A' floor| Queens Medical Centre | Nottingham | NG7 2UH This message has been checked for viruses but the contents of an attachment may still contain software viruses which could damage your computer system: you are advised to perform your own checks.

Longitudinal processing clarification
by Derin Cobia 16 Feb '10

16 Feb '10

(Questions for all, but maybe more directed towards Martin) I have some questions about manual edits in regard to the longitudinal stream. Based on the current info on the wiki page, it appears that no edits are pushed forward from the cross-sectional (initial) runs of the subject data, as any information on the *.long.* runs come from the template. However, I've noticed that WM edits and surfs from the template are used in for the *.long.* processing. In essence, my question is when/where should manual edits (i.e., control points, WM, pial edits) occur when conducting longitudinal processing in 4.5? It seems I remember that in 4.3 edits in the cross-sectional work would be pushed forward to the *.long.* images, but such is not the case anymore (?). Are edits to occur in the template (i.e., 'base') now, or in the *.long.* runs? Thanks. -Derin

a question about rebuild_gca_atlas.csh
by Guang Zeng 15 Feb '10

15 Feb '10

Hi, there, I am using the rebuild_gca_atlas.csh to build our own subcortical atals now, and met a problem at the second step which is # Train using ONE_SUBJECT, the command line is: mri_ca_train -prior_spacing 2 -node_spacing 8 -mask brain.mgz -parc_dir seg_edited.mgz -xform talairach_man.xfm -T1 norm.mgz -check $OneID /data1/radiology/m047599/temp_fs_2/freesurfer-v4.5.0/subjects/average/RB_12-Feb-2010.gca and it gave me errors such as; ERROR: Left_Caudate: 104 167 182, tal *** x=22.896236 > 5 ***, y=33.105412, z=-16.869007 ERROR: Left_Caudate: 104 167 183, tal *** x=22.900818 > 5 ***, y=34.053909, z=-16.893997 ERROR: Left_Caudate: 104 167 184, tal *** x=22.905401 > 5 ***, y=35.002407, z=-16.918985 ERROR: Left_Caudate: 104 167 185, tal *** x=22.909985 > 5 ***, y=35.950901, z=-16.943975 ERROR: Left_Caudate: 104 167 186, tal *** x=22.914564 > 5 ***, y=36.899403, z=-16.968966 ERROR: Left_Caudate: 104 167 187, tal *** x=22.919147 > 5 ***, y=37.847897, z=-16.993954 ERROR: Left_Caudate: 104 167 188, tal *** x=22.923729 > 5 ***, y=38.796391, z=-17.018944 Why it will have an error related to Left_Caudate? Is the FreeSurferColorLut.txt file called somewhere ? Thanks!

mris_ca_label: could not read surface file
by Alessandro D. Gagliardi 15 Feb '10

15 Feb '10

Dear Freesurfers, I just upgraded to the latest version of Freesurfer (leopard-i686-stable-pub-v4.5.0) and I want to rerun mris_ca_label to generate ?h.aparc.a2009s.annot files. I figured I would just run the command described at http://surfer.nmr.mgh.harvard.edu/fswiki/ReconAllDevTable, namely: mris_ca_label -aseg aseg.mgz <subjid> ?h ?h.sphere.reg $FREESURFER_HOME/average/?h.destrieux.simple.2009-07-29.gcs label/?h.aparc.a2009s.annot but when I do so, I get the following error: mris_ca_label: could not read surface file /Users/adfgagliardi/Documents/Lab/subjects/hj/surf/?h.smoothwm for hj No such file or directory surf/?h.smoothwm does exist for hj, so I don't know why it says "No such file". I tried regenerating it using mris_smooth -n 3 -nw ?h.white ?h.smoothwm which completed without error, but mris_ca_label continues to say that it cannot read ?h.smoothwm Any help would be greatly appreciated.

recon-all error during SubCort Seg
by Julie McEntee 15 Feb '10

15 Feb '10

Hello, The initial command to recon-all: recon-all -i $FREESURFER_HOME/subjects/PPG1156/1156MPRage.nii.gz -autorecon1 -autorecon2 -subjid MGZ exited with errors during SubCort Seg. At this point, I am attempting to obtain subcortical segmentation only (aseg.mgz, wm.mgz, aseg.stats), but would like to eventually run entire recon. I previosly tried to attach the recon-all.log, but the file is too large (>200KB). I checked the tal transform and skullstrip- both looked OK. The scan is of a subject with Huntington's Disease so the ventricles are a bit enlarged and there is significant asymmetrical atrophy such that at least one area of brainmask.mgz was labeled as 57 (Right-Lesion). Also, there seems to be intensity variations (artifact?) A-P across cortex on slices around mid-line in sagittal view. Any ideas? Please let me know if you'd like me to upload any/all files.
