[TRACULA] ERROR: cannot unpack mosiacs without ASCII header
by Koubiyr, Ismail 05 Jul '16

05 Jul '16

Hi everyone, I have some problems trying to run TRACULA on some DWI data. It is a mosaic Siemens DWI. I first converted the DICOM files with dcm2nii to get the bvec and bval files. Then I run the trac-all -prep -c command and I get the following error : WARNING: file /My/path/to/dicom does not contain a Siemens ASCII header has this file been anonymized? ERROR: cannot unpack mosiacs without ASCII header I tried to unpack the mosaics with gdcmtar, but I got the same error. Thank you in advance for your help, Ismail

Fwd: Failure to use yeo-7/17 networks maps as templates in MRIcron
by Hsiang-Yuan Lin 04 Jul '16

04 Jul '16

Hi Prof. Yeo, I have problems utilizing yeo 7/17 cortical network parcellation maps as templates in MRIcron (I aim to use your cortical parcellation maps to underlay my findings in order to derive the implications based on iFC networks). To be specific, there is an orientation problem in the current version of parcellation maps in MNI space. Thank you for your help in advance.

Question
by Dulce Maria Magdaleno Arroyo 04 Jul '16

04 Jul '16

Hi, I am doing a research about the uterus, in this research I am trying to define the geometry of this organ, so I want to use freesurfer to mapping the uterus into a sphere; as far as I understand I don't need all the brain image processing. I have already a FEM model of the uterus in matlab, and I was wondering if just the command mris_inflate could be used to this task or if I have to consider some other commands? Other question I have is, Do I need to convert my matlab data to .mgh to use the freesurfer commands? If yes, Could you give me some directions to do this task? In advance, thank you so much for your help. Best, DM

Hi, Why not use total surface area to control for analyses involving area, and mean cortical thickness to control for thickness?

Hi Clara, If I am understanding your question correctly, you don't need to control for brain volume when looking at thickness analyses. See quote below from this link: http://www.freesurfer.net/fswiki/eTIV "Note that this correction is only useful in situations where the structure scales with head size. Outside of this, correction just adds noise, or provides inaccurate data. In the case of the measures from Freesurfer, one would apply correction to the volume measures and not thickness measures. This is because volume scales with head size which is mostly due to changes in surface area, whereas thickness alone scales to a much less degree."

Tissue probability maps from aseg.mgz
by Lee Subin Kristine 04 Jul '16

04 Jul '16

Dear FreeSurfers, Is it possible to get tissue probability maps (for the purpose of using them in spm DARTEL, PVElab, etc) out of aseg.mgz? I did read in a previous post (https://mail.nmr.mgh.harvard.edu/pipermail/freesurfer/2007-October/006384.h…) that you can use mri_ca_label with the option -write_probs, but I could not find a -write_probs option. If not, I'm wondering is there is any other possible way to get tissue probability maps from FreeSurfer? Any help would be much appreciated. Regards, Subin

trac-all error (bvecs and bvals don't have same number of entries)
by Lars M. Rimol 04 Jul '16

04 Jul '16

Hi, Trying to run trac-all -c dmric_file -prep, I get an error message stating that there are different numbers of entries in the bval and bvec files. I don't understand why, since both have the same number of rows (64). OS = Ubuntu 14.04.4 Software: freesurfer-Linux-centos6_x86_64-stable-pub-v5.3.0; I have updated Tracula and FSL (v 5.0.9). Error message: #@# Tensor fit fr. 01. juli 19:20:29 +0200 2016 dtifit -k /media/lmr2/subjects/DTI/tracula_2016/4_FS/dmri/dwi.nii.gz -m /media/lmr2/subjects/DTI/tracula_2016/4_FS/dlabel/diff/aparc+aseg_mask.bbr.nii.gz -r /media/lmr2/subjects/DTI/tracula_2016/4_FS/dmri/bvecs -b /media/lmr2/subjects/DTI/tracula_2016/4_FS/dmri/bvals -o /media/lmr2/subjects/DTI/tracula_2016/4_FS/dmri/dtifit Error: bvecs and bvals don't have the same number of entries Linux dmed4870 3.19.0-31-generic #36~14.04.1-Ubuntu SMP Thu Oct 8 10:21:08 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux trac-preproc exited with ERRORS at fr. 01. juli 19:20:30 +0200 2016 ---------- I also tried flipping the bvec/bval files, but got the same error. I don't know if there's anything wrong with the bval/bvec files, or if this error message is indicative of some other problem. Is the updated Tracula version only compatible with the dev version of FS? I have attached the bval/bvec files and the trac-all.log. ------------------------------------------------------------------- The contents of the dmric file is: setenv SUBJECTS_DIR /media/lmr2/subjects/DTI set dtroot = /media/lmr2/subjects/DTI/tracula_2016_nativerows set subjlist = (4_FS) set dcmroot = /media/lmr2/subjects/DTI set dcmlist = ( 4/5/1.dcm ) set bvalfile = /media/lmr2/subjects/DTI/bvals_rows.csv set bvecfile = /media/lmr2/subjects/DTI/bvec_rows.csv Thank you! yours, Lars M.
