Hi Antonella what video card are you using? Did you try updating your video driver? cheers Bruce On Wed, 29 Jun 2011, Antonella Kis wrote: > > Good morning, > > Thank you very much Bruce.

registration with Melodic
by Kat Mott 29 Jun '11

29 Jun '11

Hi all, I have manually registered fMRI data that I want to run ICA on, and I want Melodic to use my register.dat file, not re-register the data using its own algorithm. Since there doesn't seem to be any way to use the register.dat file as an input, I've been trying to figure out a way to apply the registration info to the .nii file and then simply uncheck the registration options in Melodic. I used a bit of code I found in the forum archives to try this, which created, using the f.nii and register.dat file, a file called f.anat.nii. But when I tried to use this as the 4D input for Melodic I got the error 'Child process exited abnormally.' I used the following to perform the transformation into f.anat.nii: mri_vol2vol --mov f.nii --reg register.dat --fstarg --o f.anat.nii Any thoughts on how to create an input that Melodic will accept so that it will use my registration? Thanks much, Kat

MRI volume padding in pipeline
by Lukas Fiederer 29 Jun '11

29 Jun '11

Good day everyone, I received a Freesurfer processed MRI volume from a college and would like to compare it to the unprocessed data. Alas Freesurfer padded the MRI volume from [384 384 256] to [385 385 385]. I would like to revert this padding! Can someone please be kind enough to tell me in which way the pads are added, ie. how much is added on each side of each dimension. Thanks a lot, Lukas

Recon-all with mris_fix_topology error
by Jordi Casals 29 Jun '11

29 Jun '11

Hello FreeSurfer community, I am Jordi Casals, from Barcelona. After few days trying to process a set of modificactions done to a subject (pial, white matter and control points), I still have this error, about mris_fix_topology. I don't know where is the problem, because I have done a lot of subjects in the same way as these one and the other two that give me this error. SUBJECT SRN_005 DATE Wed Jun 22 00:58:31 CEST 2011 USER neuro HOST td560.pic.es PROCESSOR x86_64 OS Linux Linux td560.pic.es 2.6.18-238.9.1.el5 #1 SMP Tue Apr 12 18:53:46 EDT 2011 x86_64 x86_64 x86_64 GNU/Linux $Id: recon-all,v 1.133.2.43 2009/04/22 22:34:03 nicks Exp $ /SOFTWR/freesurfer/bin/recon-all PWD $PATH/SRN_005/scripts CMD mris_fix_topology -mgz -sphere qsphere.nofix -ga SRN_005 rh It would be be really great if someone can help me or give me some guides to understand a little bit more the problem and to reach a proper execution. Thank you again, Jordi.

Tracula question: group analysis
by Maryam Moteabbed 28 Jun '11

28 Jun '11

Hello Tracula Developers & Users, I can follow how to use the diffusion measures from pathstats.overall.txt for each subject to run a group analysis on the tracts. On the other hand I noticed there is also the pathstats.byvoxel.txt which contains various diffusion measures in each voxel along the highest probability path. What are your suggested steps for analyzing this text file for group comparison? I am guessing developers had an analysis method in mind when they decided to print this file out. Thank you in advance for your help. Best, Mary

Hi Antonella, gzip doesn't recognize your file. Can you just send us a tif? Bruce On Tue, 28 Jun 2011, Antonella Kis wrote: > > Once again thanks Bruce.

mri_glmfit-sim problem...
by Joe Andreano 28 Jun '11

28 Jun '11

Hi All, I tried using glmfit-sim to for multiple comparison correction on some previously analyzed data, and I've run into an error I don't understand: Here's the command I used: mri_glmfit-sim --glmdir tal.wrfx.arousal_v_valence_TP0 --cache 1.3 pos This generated the following error: ERROR: cannot find /usr/local/freesurfer/stable5_1_0/average/mult-comp-cor///cortex/fwhm12/pos/th13/mc-z.csd I checked the location mentioned in the message, and the mc-z.csd file is indeed there. Does anyone know what this means? Thanks, Joe _________________________________ Joseph M.

mri_volcluster in single direction
by G. William Chapman IV 28 Jun '11

28 Jun '11

Hello All, I've been using fslstats to create a mask of voxels reaching a certain threshold and then using mri_volcluster to reduce the mask down to just clusters above 3 voxels. Now we're trying to filter them down to just those clusters that have more than 3 contiguous voxels in a single direction, rather than total volume. I can't find anything in the help file on this, but I was wondering if there's possibly an undocumented flag in mri_volcluster that would do this? Thanks! ----- G.
