mkanalysis-sess
by Samantha Clark 24 Feb '10

24 Feb '10

Hi, I have a question regarding creating a paradigm file and the command mkanalysis-sess. I am trying to analyze resting state data and wanted to know what the contents of the paradigm file should be. Also what would my mkanalysis-sess command be? Not sure what the -designtype and other options would be in this case. Can you please help? Thanks, Samantha

nmr-std-env error on seychelles
by Maximilien Chaumon 24 Feb '10

24 Feb '10

Hi Freesurfers, I have an issue with a job I launch on seychelles. I get this error message: /usr/local/freesurfer/nmr-std-env: line 98: syntax error near unexpected token `(' /usr/local/freesurfer/nmr-std-env: line 98: ` set path = ( /usr/pubsw/bin $path )' /var/spool/PBS/mom_priv/jobs/1258634.sey.SC: line 13: isxconcat-sess: command not found Since this is not a file I edited myself, I wonder what's wrong... Thanks, Max

convert vertex in tksurfer to point in tkmedit
by Guang Zeng 23 Feb '10

23 Feb '10

Hello, there, I load lh.inflated of a subject using tksurfer, click a point (or vetex), then Click "Save Point") Meanwhile, I load the same subject in tkmedit, select "goto save point", I can see the saved point. If I try to convert multiple points (or vertices) from tksurfer to tkmedit, is there an equation? I guess I am looking for the equation which can convert Vertex RAS to Volume Index. Thanks!

Re: [Freesurfer] recon-all doesn't recon-all

Thank you for your help. It again only ran for a minute. The difference this time seemed to be that it asked me to rerun the command with -force. I wrote out s0964091@CRIC-0012:~$ SUBJECTS_DIR=~/Desktop/Allimages/MRIscan/janani/CRIC-0014_5679.adb.DICOM to start with. Then I typed out what you sent s0964091@CRIC-0012:~$ recon-all -i /home/s0964091/Desktop/Allimages/MRIscan/janani/CRIC-0014_5679.adb.DICOM/Dhinakaran^Janani^-0002-0001-00001.dcm -i /home/s0964091/Desktop/Allimages/MRIscan/janani/CRIC-0014_5679.adb.DICOM/Dhinakaran^Janani^-0004-0001-00001.dcm -s subj001 ERROR: /home/s0964091/Desktop/Allimages/MRIscan/janani/CRIC-0014_5679.adb.DICOM/subj001 exists, delete or re-run with -force So I added -force to the beginning which caused an error- s0964091@CRIC-0012:~$ -force recon-all -i /home/s0964091/Desktop/Allimages/MRIscan/janani/CRIC-0014_5679.adb.DICOM/Dhinakaran^Janani^-0002-0001-00001.dcm -i /home/s0964091/Desktop/Allimages/MRIscan/janani/CRIC-0014_5679.adb.DICOM/Dhinakaran^Janani^-0004-0001-00001.dcm -s subj001 No command '-force' found, did you mean: Command 'zforce' from package 'gzip' (main) -force: command not found I tried adding it in the end and as I said earlier, it ran well but only for a minute.

Troubleshooting incorrect annotations (cortical parcellation)
by Samuel Inverso 22 Feb '10

22 Feb '10

Hi All, It looks like the annotations are incorrect here, with the Parieto-occipital fissure annotated as the calcarine fissure on the attached surfaces. (Possibly because the occipital cortex seems to be squashed downwards?) The annotations are aparc.a2009s If that's, correct is there a method to fix the annotations? Thank you in advance for any help. Best regards, -Sam

Error during Fix Topology
by Joonkoo Park 22 Feb '10

22 Feb '10

Dear FreeSurfers, I got an error during Fix Topology step (seems like from the right hemisphere) in the recon-all process (see below for more information). I searched the ListServ and learned from other email threads that this may be due to incorrect segmentation of WM or Cerebellum, or possibly from skull stripping. I tried to follow the tutorial on manually fixing topological defects (http://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/TopologicalDefect) However, I wasn't sure what to look for because my current result does not yet have rh.white which allows to view WM segmentation in tkmedit window (or am I right?). What shall I do at this point? I'm very new to FreeSurfer, so it'd be great if anyone can give me some step-by-step approaches to troubleshoot this. Thanks.

tkregister2 problems
by Sebastian Moeller 22 Feb '10

22 Feb '10

Dear Freesurfer Experts, I am a happy user of freesurfer for a number of years now. And finally I managed to switch over from v3.0.5 to 4.5.0. Most of this switch was pretty straightforward only slowed down by a few self-inflicted complications. One of the consequences of switching to V4 is that most of my functional 4D volumes now are floats instead of the short we used before. And regarding the floats, I just encountered a weird issue with tkregister2 (from freesufer-linux-centos4_x86_64-stable-pub-v4.5.0-full). I try to register 2 uncompressed single file nifti files, and the target does not appear only the moveable (when I hit the target button on the gui I just the image window turns black). Interestingly this also happens when I load the same volume as target and moveable: tkregister2 --regheader --reg tmp.reg --targ ./bold/003/f.nii --mov ./bold/003/f.nii -> nicely visible mov invisible targ, also fmo-targ does not help. however if I convert the file to int or short the targ becomes visible again: mri_convert -i /bold/003/f.nii -o /bold/003/fi.nii -odt int tkregister2 --regheader --reg tmp.reg --targ ./bold/003/fi.nii --mov ./bold/003/fi.nii -> nicely visible mov and targ, also: tkregister2 --regheader --reg tmp.reg --targ ./bold/003/fi.nii --mov ./bold/003/f.nii -> nicely visible mov and targ, but note: mri_convert -i /bold/003/fi.nii -o /bold/003/ff.nii -odt float tkregister2 --regheader --reg tmp.reg --targ ./bold/003/ff.nii --mov ./bold/003/ff.nii -> nicely visible mov invisible targ, So it looks like tkregister2 does not really like floats. Is there any thing I can do to work around this problem short of mri_converting all templates to temporary ints? I would be happy to help debug this issue, so please let me know what I can do to help. best regards & thanks for all the cool tools in freesurfer Sebastian -- Sebastian Moeller telephone: 626-395-6713 fax: 626-395-8826 German GSM: 0 15 77 - 1 90 31 41 moeller(a)caltech.edu Division of Biology MC 114-96 California Institute of Technology 1200 East California Boulevard CA 91125, Pasadena USA

BrainSegVol in asegstats table
by Michael Waskom 22 Feb '10

Hi all, What is the definition of the "BrainSegVol" field when you print the segmentation stats to a table? It's smaller than just adding up all of the other fields in the table. Thanks! Best, Mike

mri_vol2surf resulting in different dimensions for two different images in the same space
by Joonkoo Park 22 Feb '10

22 Feb '10

Dear Surfers, I (successfully) resampled a functional data on the surface map using mri_vol2surf: > mri_vol2surf --mov func.nii --reg register.dat --projfrac 0.5 --interp nearest --hemi lh --o lh.func.mgh Then, I normalized this image to a standard space (fsaverage) using mri_surf2surf: > mri_surf2surf --srcsubject sub1 --trgsubject fsaverage --sval sub1/lh.func.mgh --tval sub1/lh.func.norm.mgh --fwhm 5 --cortex --hemi lh The dimension of the output file, lh.func.norm.mgh, was 163842 x 1 x 1 (identified from mri_info). This file can be opened from Matlab, and I can successfully get access to 163842 vertices. What I want now is to take the aparc+aseg information from the average brain (fsaverage) and be able identify which vertex falls under which ROI label. I decided to resample aparc+aseg.mgz in fsaverage on the surface map, hoping to get label information at the dimension of 163842 x 1 x 1. So I ran: > mri_vol2surf --mov fsaverage/mri/aparc+aseg.mgz --regheader fsaverage --projfrac 0.5 --interp nearest --hemi lh --o fsaverage/surf/lh.roi.mgh > mri_vol2surf --mov fsaverage/mri/aparc+aseg.mgz --regheader fsaverage --projfrac 0.5 --interp nearest --hemi rh --o fsaverage/surf/rh.roi.mgh The resulting mgh files, however, had a dimension of 23406 x 1 x 7. 1. As I said, I wanted to get label information (roi number from the FreeSurferColorLUT) for each vertex of the surface image in the fsaverage space. Is this the right approach? And did I do this correctly (I'm concerned about many options above)? 2. If so, why is the resulting dimension different from the other one? I assume that it's probably a reshape issue, but how I can reshape the dimension to match 163842 x 1 x 1? Thanks in advance.
