Hi Ruopeng, yep, this fixes the problem and explains the user specificity. Excellent work!

The work around is to set your terminal to English before running freeview. You can run something like this: setenv LANG en Then run freeview. Let me know if that works.

Re: [Freesurfer] ERROR: comparison in expression (FS with SGE)
by Xue, Feng 19 May '12

Sorry, I didn't notice that the reply address was not the list, I've done re-post it. Is there any method to check whether it is ok? For SGE, it might only write errors to dot e files instead of warnings. It seemed like a shell syntax error, however, I don't have that experience to check the recon-all script.

p.s. looks like an intensity normalization failure. Can you give us details of the acquisition? Sequence name, voxel resolution, etc....?

how to edit the pial surface
by 李盟 19 May '12

19 May '12

Hi FreeSurfer Experts, I had 2 question about the output troubleshooting. 1) when I used the mri_convert command, the format of the input image I choosed was 4D nii format, but not the original dicom format, which would affect the result of reconstruction? 2) When I checked the quality of output using tksurfer, I found the color line representing the surface (pial and white) were not along the folding pattern, and the distance between the two sufaces was rather short. Whether or not it was caused by the bad GM/WM contrast? What is the best way to deal with them? Thanks. Meng Li

How to use aparcstats2table and asegstats2table for rois generated from QDEC group analyses
by Vy Dinh 18 May '12

18 May '12

Dear Freesurfer Experts, I've created a couple of ROIs from qdec comparisons of thickness and volume between two groups. We extracted the data from these ROIs for each subject using mris_anatomical_stats. The stat files are located within each subjects folder: sub/stats/rh.roi.stats Now, we would like to combine the data from each stat file to a text file using aparcstats2table and asegstats2table (for volume measures). I already have batch scripts that call these functions for multiple subjects. The script basically concatenates all of the subject ids and inputs the concatenated string into the aparcstats2table (or asegstats2table) command. EX: asegstats2table -s s1 -s s2 -s s3 -s s4 --hemi lh --meas volume -tablefile test_stats.txt I would like to modify my script so that I can extract the data from the roi.stats file. This is only a matter of entering the correct inputs for aparcstats2table and asegstats2table but I have tried with little success. The problems with each command are explained below. *For asegstats2table:* According to documentation ( http://surfer.nmr.mgh.harvard.edu/fswiki/asegstats2table) I have tried running "asegstats2table $STRING --meas volume --skip --tablefile $OUTFILE " where string is "-i s1/stats/lh.roi.stats -i s2/stats/lh.roi.stats ......etc" but get the error message: Building the table.. Traceback (most recent call last): File "/Users/skip/Desktop/harlow_mount/apps/fmri_progs/freesurfer_v51/freesurfer/bin/asegstats2table", line 513, in <module> rows, columns, table = sanitize_table(options, pretable) File "/Users/skip/Desktop/harlow_mount/apps/fmri_progs/freesurfer_v51/freesurfer/bin/asegstats2table", line 412, in sanitize_table _specs, _id_name_map, _measl = _t[0] IndexError: list index out of range *For aparcstats2table: * when I run the command: aparcstats2table $STRING --hemi lh --parc roi_name --skip --tablefile $OUTFILE where string is "-s s1 -s s2 -s s3 ", I get a text file with 3 columns. The first column lists the subject ids, but what are the values for the 2nd and 3rd columns? Also, is it possible to input more than 2 .stats file for the command? Looking forward to your responses, Vy Vy T.U. Dinh Neurological Sciences Rush University Medical Center Phone: (312) 563-3853 Fax: (312) 563-4660 Email: Vy_dinh(a)rush.edu

How to calculate Total Brain Volume from aseg.stats
by Goldman, Aaron (NIH/NIMH) [C] 18 May '12

18 May '12

Hello, For an analysis, we're trying to calculate a Total Brain Volume covariate based on the data in aseg.stats, generated using version 5.0.0. Basically, we want to include all WM and GM but not CSF. I was thinking of doing Total GM + Cortical WM + L&R Cerebellum WM. Would this be the correct way to do it, or should we use some other combination? Thanks, Aaron

splitting data into virtual runs
by Guthormsen, Amy M 18 May '12

18 May '12

Hello, I would like to use fsfast to analyze retinotopic data that I collected. I used the traditional 4 stimulus types (clockwise, counterclockwise, expanding, and contracting), but rather than collect each one in its own run, I took data from one long run that contained all the stimuli. Based on the logs, I can associate the pulse number/dicom file number with a stimulus type. However, when I tried to just move the sets of dicom files into sub-directories, which I set up as run directories, freesurfer still saw them as belonging to one run (which I assume is taken from meta-data). My question is, how can I best split up these files so that I can subject them to the FsFastIndividualRetinotopyAnalysis<http://surfer.nmr.mgh.harvard.edu/fswiki/FsFastIndividualRetinotopyAnalysis…> process? Thank you, Amy Guthormsen

Question about DODS model and DOSS model
by ZhiLiangLong 18 May '12

18 May '12

Hi all: I'm a little confused about the DODS model and DOSS model. I have two groups (patient and control) and one covariate (age), and I want to compare the diffirence of thickness between the groups with age as the covariate. In DODS model, is the process the analysis of variance substantially (group is a factor and age is another factor)? Generally, if there is no interaction between age and group, then i can re-run with the DOSS model to increase the statistical power.But i don't know how to determine whether there is no interaction . I hope someone give me some suggestions.
