Tracula shows some tracks with bbr and others with flt
by Salil Soman 06 Feb '14

06 Feb '14

Hi, I have a couple of dti cases where bbr will include forceps major and missing forceps minor and flt will be the opposite. Similar things have occurred for anterior thalamic tracts and cingulum bundles. Any suggestions on what I may be doing incorrectly? Best wishes, Sal

Hi, How can I convert freesurfer .thickness files into .nii volume data to analyze in SPM I have already converted the .thickness files into .nii format by using mri_convert command but the converted files can not be visualize in spm probably I need to project the thickness on anatomical volume to visualize it correctly in spm can anyone help me waiting for your replies Thank you Best Regards, Muhammad Naveed Iqbal Qureshi P please don't print this e-mail unless you really need to

upgrading to freesurfer 5.3
by Laura Christine Anderson 05 Feb '14

05 Feb '14

Hi Anastasia, I was hoping to upgrade to Freesurfer 5.3 in order to use the new motion detection feature of Tracula. The issue is that all of the preprocessing has already been completed in Freesurfer 5.2 with the older version of Tracula. Would I need to redo all the preprocessing in 5.3 in order to use the new motion detection feature? Thanks for your help! Laura Laura C.

What it should contains?Thanks, Stefano

"trac-all -prior" giving "Segmentation fault (core dumped)
by Yong-Hwan Kim 05 Feb '14

05 Feb '14

Hello, FreeSurfer community, I'm trying to run TRACULA sequentially. After running, "trac-all -prior -s <subject> -i <input_DWI.nii> -c <tracula_conf.txt>" that shows an error "Segmentation fault (core dumped)" in my server. (Other options, "-corr, -qa, -intra, -inter, -masks, -tensor", were have done without error) Server was configured as, 1. Fedora 13 - 64bit 2. FreeSurfer v5.1 3. Tracula v5.3 (updated from v5.1) Can anyone suggest a reason why this would be the case?

Hi list, SLFP is SLF III? Is there a way to obtain by TRACULA also SLF I and II, knowing the the cortical targets of the tracts? Thanks, Stefano

TRACULA error: pre-processing
by Won Sang Jung 05 Feb '14

05 Feb '14

Hi, I have a problem running TRACULA in the pre-processing stage. The error message is the following; Loading streamline start ROI from /usr/local/freesurfer/subjects/tracula/tutorialdata/diffusion_tutorial/Diff001/dlabel/mni/lh.cst_AS_roi1.flt.nii.gz niiRead(): error opening file /usr/local/freesurfer/subjects/tracula/tutorialdata/diffusion_tutorial/Diff001/dlabel/mni/lh.cst_AS_roi1.flt.nii.gz ERROR: Could not read /usr/local/freesurfer/subjects/tracula/tutorialdata/diffusion_tutorial/Diff001/dlabel/mni/lh.cst_AS_roi1.flt.nii.gz Linux localhost.localdomain 2.6.18-371.1.2.el5 #1 SMP Tue Oct 22 12:51:53 EDT 2013 x86_64 x86_64 x86_64 GNU/Linux trac-preproc exited with ERRORS at 2014. 01. 23. (목) 18:32:17 KST I guess this error started to happen after I updated Freesurfer version 5.3.0 (I could successfully run TRACULA with same data with the prior version of Freesurfer) In my setting, $TUTORIAL_DATA --> /usr/local/freesurfer/subjects/tracula/tutorialdata I tried re-download the file, diffusion_tutorial.tar.gz, from freesurfer server and extracted file again, but still I couldn't find the file "lh.cst_AS_roi1.flt.nii.gz" in Diff001/dlabel/mni folder. Thank you in advance for your advice. Wonsang Jung

Outputting all tracula statistics to table
by Salil Soman 05 Feb '14

05 Feb '14

Hi, What is the proper way to generate a single table containing all tracula generated statistics for all subjects in a study? I tought tractstats2table was the way to do this, I am confused as to how trac-all -stat factors into this process in the latest (12-09-13 version)? Thank you. -Sal

Tracula: from anatomical to diffusion space and FSL probtracx
by Garikoitz Lerma-Usabiaga 05 Feb '14

05 Feb '14

Hi Anastasia, I want to use a hippocampal subfield as a seed in FSL. I am having problems understanding how to change spaces around... 1.- Is this command ok? mri_vol2vol --mov dmri/dtifit_FA.nii.gz --targ mri/hippo_subfield_in_anatomical_space.mgz --inv --interp nearest --o mri/hippo_subfield_in_diffusion_space.nii --reg dmri/xfms/anatorig2diff.bbr.dat --no-save-reg 2.- I would like to visualize it in freeview in anatomical space to check if it is ok, if I load nu.mgz and hippo_subfield_in_anatomical_space.mgz and then load hippo_subfield_in_diffusion_space.nii with the registration file dmri/xfms/anatorig2diff.bbr.dat, should I visualize it ok? If I don't register it, they show to be displaced (more than expected). 3.- Afterwards I want to run probtracx with the following command (my doubt is mainly about the files to use, since FSL files are RAS, freesurfer anatomical are LIA and freesurfer diffusion are LIA, are all the files in the same format and FSL is ok with it?): /usr/local/fsl/bin/probtrackx --mode=seedmask -x mri/hippo_subfield_in_diffusion_space.nii -s dmri.bedpostX/merged -m dmri.bedpostX/nodif_brain_mask -o fdt_paths_hippo_subfields --dir=FSL_ConnResults_Hipp -c 0.2 -S 2000 --steplength=0.5 -P 5000 --opd many thanks! Gari
