Problem with tracula: incomplete or lacking tracts
by stdp82＠virgilio.it 28 Mar '13

28 Mar '13

Hi Analstasia, as you suggest, adjusting brain mask the tracts are better. Now I'd like to perform trac-all with new version by using a new configuration file. I do not understand what I should do for: 1- set b0mlist2- set b0plist Thanks.

Incorporating (high resolution) T2- and FLAIR volumes
by Lukas.Scheef＠ukb.uni-bonn.de 28 Mar '13

28 Mar '13

Hi FreeSurfer experts! We have isotropic T1/T2 and FLAIR volumes for a larger cohort. It would be fine to use the T2 / FLAIR volumes to improve the segmentation and to perform a couple additional analyses using FS. This leads to the following questions: 1) How do I incorporate T2/Flair volumes into the recon all processing stream? a) Would it be like: recon-all bert -all -T2 /luke/xyz/007-T2.nii ? b) What is expected to get the better results regarding the pial surface: FLAIR or T2? (both are at 1x1x1mm) 2) Is there any module in FS to detect white matter lesions? 3) How can I perform myelin mapping using the ratio method (T1w/T2w)? Or do I have to switch to Caret? Many thanks in advance for your help and advice! Best wishes, Luke

Bug in DOSS implementation in QDEC

Dear FreeSurferers, it has just come to my attention that there may be a bug in the way that QDEC computes contrasts for DOSS. If you are using QDEC in this way, please hold off until I track down the problem. Also, please let me know if you are using it in this way. thanks and sorry for the inconvenience doug -- Douglas N.

Recon-all errors (reposting)
by Marcos Martins da Silva 28 Mar '13

28 Mar '13

Hi, freesurferers I am trying to execute the post installation tests as recommended at Freesurfer Wiki. Using a CentOS6 Virtual Machine (kernel 2.6.32-358.2.1.el6.x86_64) over Fedora 18 using VirtualBox 4.2.8. Freesurfer version is 5.2. Tkmedit, Tksurfer, qdec and freeview all work great. However, recon-all tests return errors.

Re: [Freesurfer] Underestimated Pial surface - after deleting problematic voxels

well, something is really wrong. Did you happen to change the voxel type of brain.finalsurfs.mgz? Can you run mri_info on it and send us the results? If not, then upload the tarred and gzipped subject dir and I'll take a look. I don't think it will be hard to fix On Thu, 28 Mar 2013, preciado(a)nmr.mgh.harvard.edu wrote: > A) Log attached. > B) That was my next step but I wanted to check first to see if there was > something obvious I was missing. > > I actually ran "recon-all -autorecon-pial -subjid subject_name" twice.

Underestimated Pial surface - after deleting problematic voxels
by preciado＠nmr.mgh.harvard.edu 28 Mar '13

28 Mar '13

Hello Freesurfers, I ran recon-all on a subject's structural data like so: recon-all -autorecon-all -subjid subect_name The resulting pial surface looked pretty good except that there were a few voxels of dura and cerebellum that were included in the pial surface. not a big deal. I deleted some voxels of dura from brainmask.mgz and deleted voxels of from the cerebellum by creating and saving a copy of brain.finalsurfs.mgz. /subject_name/mri/ cp brain.finalsurfs.mgz brain.finalsurfs.manedit.mgz Then I ran recon all to regenerate the pial surface: recon-all -autorecon-pial -subjid subject_name The results from the pial surface redrawing are now totally wrong and completely underestimated. The weird thing is that it looked perfectly fine before and removing some problematic voxels caused this result. Any insights as to how/why this occurred and how to fix it? Images of the AFTER picture attached. Thanks! -Ronny

Hi list,I'm performing qdec. This my file.dat1 diagnosis discrete 2 1 Pathology 2 Controls2 Thickness_lh continuous 03 Thickness_rh continuous 04 NPStest continuous 0 Continuous Factors: Mean: StdDev: ------------------- ----- ------- Thickness_lh 2.643 0.116 Thickness_rh 2.630 0.099 NPStest 0.774 1.203Number of subjects: 31Number of factors: 4 (1 discrete, 3 continuous)Number of classes: 2Number of regressors: 8NPStest is scored from 0 to 8 and for controls it is all 0.Previously I have performed qdec without problem but I'm noting that when I use covariates that contains all 0 in a group, qdec give me an error. What's happen?Thanks, Stefano

bbregister error with hardi data
by Corinna Bauer 27 Mar '13

27 Mar '13

Hello all, I am attempting to run bbregister on 4D HARDI data that has already been motion, eddy, and epi-distortion corrected in fsl. I run the command: bbregister --s lindsay --mov hardi/ffiltered_func_data_01.nii.gz --dti --init-fsl --reg register.dat and get a number of errors that seem to begin in the mri_convert section as seen below.
