FLASH atlas
by Derin Cobia 21 Jul '06

21 Jul '06

Hello, I read in the archive that you were planning on releasing two new atlases (for MP-RAGE and FLASH) last year. Were those (or even newer ones) distributed? I have some FLASH sequences I want to run. Thanks! -Derin

source of thickness information for mris_preproc
by Lars M. Rimol 21 Jul '06

21 Jul '06

Hi, When one runs mris_preproc with e.g. -meas thickness, does it get the thickness information from the files in the stats directory within each subject's directory - or from the ?h.thickness files under the surf directories? Thank you! -- yours, LMR

Dear List, I used tksurfers 'make frame' button to save frames to a movie. What type of movie file is generated by this function, and which viewer or converter could I use to see or convert it?

Hello, I received an error when running recon-all. It seems to have run into a problem during the 'Remove Neck' and 'SkullLTA' steps. I have included the output below of the last two steps before the error occured. Thank you. -Surina #@# Remove Neck Wed Jul 19 15:26:17 EDT 2006 mri_remove_neck -radius 25 nu.mgz transforms/talairach.m3z /usr/local/freesurfer/stable/average/RB_all_2006-02-15.gca nu_noneck.mgz erasing everything more than 25 mm from possible brain reading atlas '/usr/local/freesurfer/stable/average/RB_all_2006-02-15.gca'... setting gca type = Normal gca type reading input volume 'nu.mgz'... reading transform 'transforms/talairach.m3z'... mghWrite(nu_noneck.mgz, -1): could not open file gcam->type = vox reading labels out of gcam file... removing structures at least 25 mm from brain... 11405488 nonbrain voxels erased writing output to nu_noneck.mgz... nonbrain removal took 23 minutes and 41 seconds. #-------------------------------------- #@# SkullLTA Wed Jul 19 15:50:02 EDT 2006 mri_em_register -skull -t transforms/talairach.lta nu_noneck.mgz /usr/local/freesurfer/stable/average/RB_all_withskull_2006-02-15.gca transforms/talairach_with_skull.lta aligning to atlas containing skull, setting unknown_nbr_spacing = 5 using previously computed transform transforms/talairach.lta reading 1 input volumes... logging results to talairach_with_skull.log reading '/usr/local/freesurfer/stable/average/RB_all_withskull_2006-02-15.gca'... setting gca type = Normal gca type average std = 23.5 using min determinant for regularization = 55.2 0 singular and 6473 ill-conditioned covariance matrices regularized reading 'nu_noneck.mgz'... zcat: /autofs/space/tango_003/users/recon_modygp/surina/mody096/mri/nu_noneck.mgz.gz: No such file or directory mghRead(/autofs/space/tango_003/users/recon_modygp/surina/mody096/mri/nu_noneck.mgz, -1): read error mri_em_register: could not open input volume nu_noneck.mgz.

error nu_correct
by skloeppe＠uke.uni-hamburg.de 20 Jul '06

20 Jul '06

Hi freesurfers, the script crashed when running "recon-all -s bert -all" to test a newly installed CentOS 4 version (v3.0.3) on a Windows XP system with VMware and Fedora Core 4. The path for both nu_correct (and nu_estimate_np_and_em: see second error message) seem to be correct (/mnt/d/Freesurfer/freesurfer/mni/bin/nu_correct). Any suggestions greatly appriciated Thanks, Stefan The error is as follows: #@# Nu Intensity Correction Thu Jul 20 07:47:00 BST 2006 mri_nu_correct.mni --i orig.mgz --o nu.mgz --n 2 /mnt/d/Freesurfer/freesurfer/subjects/bert/mri /mnt/d/Freesurfer/freesurfer/bin/mri_nu_correct.mni --i orig.mgz --o nu.mgz --n 2 nIters 2 $Id: mri_nu_correct.mni,v 1.3 2005/12/08 01:27:21 greve Exp $ Linux localhost.localdomain 2.6.15-1.1830_FC4 #1 Thu Feb 2 17:23:41 EST 2006 i686 athlon i386 GNU/Linux Thu Jul 20 07:47:00 BST 2006 Setuid/gid script is writable by world. tmpdir is ./tmp.mri_nu_correct.mni.10059 /mnt/d/Freesurfer/freesurfer/subjects/bert/mri mri_convert orig.mgz ./tmp.mri_nu_correct.mni.10059/nu0.mnc mri_convert orig.mgz ./tmp.mri_nu_correct.mni.10059/nu0.mnc reading from orig.mgz...

eTIV on older recons
by David Ziegler 20 Jul '06

20 Jul '06

Hello All! I'm trying to calculate eTIV (ICV) based on the new Buckner method, but for reconstructions that were completed prior to the most recent stable release (in 2003-2004). Are there any extra steps or special files that I should be aware of to make this run properly? Is the procedure for estimating ICV on older recons documented anywhere? I tried running mri_label_volume using the only .lta file available in the subject/mri/transforms directory (talairach_with_skull_un5_tinit_noneck_both_uns3.lta) but the resulting eTIV outputs are much smaller than one would expect. Here's a sample command and output: [engram:emoaging] (nmr-std-env) mri_label_volume -eTIV $SUBJECTS_DIR/emot_118/mri/transforms/talairach_with_skull_un5_tinit_noneck_both_uns3.lta $SUBJECTS_DIR/emot_118/mri/aseg.mgz 17 53 using eTIV from atlas transform of 878 cm^3 processing label 17... 3730 voxels (3730.0 mm^3) in label 17, %0.424837 of eTIV volume (877983) processing label 53... 3738 voxels (3738.0 mm^3) in label 53, %0.425748 of eTIV volume (877983) Any advice? Thanks! David

Group-Specific template
by Chacko Cherian 19 Jul '06

19 Jul '06

Hello everyone, I would like to run a group-specific template on Freesurfer and compare my results with the default template(which is MNI,I assume)? Is this possible?Can I do cortical thickness measurement also in the same way? Thanks in advance, Chacko. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
