Re: [Freesurfer] Corrections with white matter
by Antonella Kis 14 Jul '11

Hi Bruce, Thanks again for helping so much. But how about the example in the tutorial * FsTutorial/WhiteMatterEdits.I was following the example in how to fill the cutting into for yellow line. There is mentioned only to open the brainmask and wm.mgz and switching/checking between the two volumes. Will be this OK? Many thanks, Antonella ________________________________ From: Bruce Fischl <fischl(a)nmr.mgh.harvard.edu> To: Antonella Kis <atorok9(a)yahoo.com> Sent: Wed, July 13, 2011 4:36:21 PM Subject: Re: Corrections with white matter Hi Antonella, you can't tell whether it is correct from overlaying it on the wm.mgz. You need to look at it over the MRI itself (either the norm.mgz or the orig.mgz) and see if you would have drawn it in the same place. The place where the yellow line doesn't follow the voxel surface is where a topological defect was corrected. It will be topologically correct, but possibly not geometrically so.

QC Montages error
by Chindhuri Selvadurai 14 Jul '11

14 Jul '11

I am getting an error when using a script that combines these 3 actions: preproc.sh std_map_qc_montages.bash put_tpef.bash Freesurfer version 4 SUBJECTS_DIR: /cluster/manoach/AS/RespMon12C/subjects Script: /cluster/manoach/AS/RespMon12C/scripts/preproc_std_qc_montages_put_tpef.sh It looks like the preproc-sess finishes okay, but the problem starts afterwards, but I'm not sure how to fix this easily.. it looks like it's looking for files that aren't there, but I haven't gotten this error before.

longitudinal base creation error
by Jessica Liu 13 Jul '11

13 Jul '11

Hi all, I'm trying to analyze longitudinal data with for a subject with six time points. However, when I try to create a within-subject template using all six time points, I get the following error message on TP 3: Resolution: 0 Iteration(single-prec): 1MRIalloc(256, 256, 256): could not allocate 262144 bytes for 140th slice Cannot allocate memory Linux HMRI-HP.SME 2.6.35.6-45.fc14.i686 #1 SMP Mon Oct 18 23:56:17 UTC 2010 i686 i686 i386 GNU/Linux recon-all -s MKA_base exited with ERRORS at Wed Jul 13 14:55:32 PDT 2011 After trying again using only five of the six time points, this occurs on TP 4: Resolution: 0 Iteration(single-prec): 1 -- diff. to prev. transform: 0.114929 Iteration(single-prec): 2terminate called after throwing an instance of 'std::bad_alloc' what(): std::bad_alloc Abort (core dumped) Linux HMRI-HP.SME 2.6.35.6-45.fc14.i686 #1 SMP Mon Oct 18 23:56:17 UTC 2010 i686 i686 i386 GNU/Linux recon-all exited with ERRORS at Wed Jul 13 11:52:31 PDT 2011 Is there any way to avoid these errors while using all of the time points? Is it even necessary to use all six time points when creating the base (it's over the course of ~1.5 years), or could I just use two or three? Thanks! Jessica

error messages in running mri_convert
by Yajun Fang 13 Jul '11

13 Jul '11

Hi, I used to be able to run command "mri_convert" in the matlab environment through "system" command. Now I received the error messages as below: mri_convert: error while loading shared libraries: requires glibc 2.5 or later dynamic linker Any suggestions ? Is it related to the new update of freesurfer ? If I switch to another server, the problem did not exist. But can I still run the command in the same server ? I am looking forward to your suggestions. Thank you ! best, Yajun

tracula - fix bad bbregister's
by GREGORY R KIRK 13 Jul '11

13 Jul '11

Hi, I processed about 80 subjects with -prep stage and then checked the bbregister registrations with tkregister2 --mov /study5/aa-scratch/TEENEMO/freesurfer_local/toot/057/dmri/dwi.nii.gz --reg /study5/aa-scratch/TEENEMO/freesurfer_local/toot/057/dmri/xfms/anatorig2diff.bbr.dat --surf found 17 subjects with bad registrations, as always because the fsl registration initialization was bad. so now i manually fix the registeration and use the manual fix for the initialization and rerun bbregister and get a good registration. so now i need to rerun -prep phase but have it use the good registration instead of computing a new bbregister registration. will trac-all -prep -nointra -c configfile accomplish this or do i need to get in and tinker with the scripts to make it run everything including computing new fsl and inverse registration matricies but using my bbregister good registration. thanks greg

reg-feat2anat: correct anat2exf.register.dat only or also func2std?
by Agnieszka Burzynska 13 Jul '11

13 Jul '11

Dear experts, I am using reg-feat2anat to register my functional data from FSL to anatomical and starndard space in Freesurfer. For some subjects the registration is bad. I can easily fix anat2exf.register.dat. However, as specified in reg-feat2anat help, I know that the registration failed as the func2std is incorrect, too. Is it enough to correct anat2exf.register.dat to correctly transfer functional data from feat to the surface space or do I also need to correct func2std? It seems to me that in the next steps I am using, such as sampling the functional data to fsaverage and further calculations in the fsaverage space do not rely on func2std. Is this correct? Cheers, Aga

Hi Antonella those look good to me. Note that you can't tell defects from a single slice. You need to scroll back and forth and look in different orientations. That said, the surfaces look pretty accurate cheers Bruce On Wed, 13 Jul 2011, Antonella Kis wrote: > Good morning Bruce, > I am checking my data after recon-all data pre-process.

-legacy flag in version 5.1

Hi everyone, Just a quick question: I noticed that the -legacy option of recon-all was removed in version 5.1. Is there any way to keep the manual edits and all the processing from previous versions while reprocessing with 5.1? Thank you very much, Marie

hi, if you have pointers to publicly available DICOM data or willing to share such data publicly from different scanners and acquisition sequences for structural, diffusion and functional data from human participants, please contact me off list. currently, the more varied the scanners and sequences, the better. i'm not looking for full datasets here, but primarily the ability to mine the various tags and metadata that exist across common image acquisitions. cheers, satra
