[Freesurfer] mris_preproc skips subjects
Dear Freesurfers, Sorry for this newbie question: I'm preparing my data for a group analysis using mris_preproc: mris_preproc --fsgd nocov.fsgd --target fsaverage --hemi lh --meas thickness --out lh.nocov.thickness.00.mgh I have 120 subjects in total and my FSGD file simply looks like this GroupDescriptorFile 1 Class Group1 Class Group2 Input pt01 Group1 Input pt02 Group1 [..rest of lines left out..] Input ct01 Group2 Input ct02 Group2 [..rest of lines left out..] When I run mris_preproc, the program only assembles the first two subjects in group 1 and the first subject in group 2, i.e. 3 subjects not 120. I have run -make all on all subjects and there is nothing to make. I'm running ver. 5.3.0 What is wrong?

Re: [Freesurfer] mris_preproc skips subjects
Hi again, I'm still totally stuck here. Any idea what the problem might be? I tried running mris_preproc with the --s option instead of --fsgd and this apparently works for all subjects that I tried so far. Now, using --fsgd, mris_preproc only processes the first subject in group 2?!

[Freesurfer] Bad design matrix
Dear all, I'm comparing cortical thickness of a group of patients to a group of controls. I want to regress out the effects of gender, age, disease severity and disease duration. For the controls, the last two parameters equals zero. When running mri_glmfit, i get ERROR: matrix is ill-conditioned or badly scaled, condno = 1e+08 See the design matrix attached. My contrasts are set as 1 -1 0 0 0 0 0 0 0 0 and -1 1 0 0 0 0 0 0 0 0 What should I do to improve this?

Re: [Freesurfer] Bad design matrix
Thanks Doug. Any suggestions for a more appropriate design? I guess this is a common situation where two or more parameters only apply to one group (in this case patients) and are zero or constant in the other.

[Freesurfer] V3A ROI?
Dear experts, I am trying to find a probabilistic map of the visual cortical area V3A. I have not been able to find this particular area in the standard atlases in FSL or FreeSurfer. The Jülich Histological atlas contains a V3V ROI but not V3A. Do any of you know have this ROI as a file or do you know of an atlas which contains it? An estimation based on an experiment, e.g. an average from retinotopic maps of healthy subjects would also be very helpful.

[Freesurfer] Extracting thickness values using labels
Dear Freesurfers, This is probably a very basic question, but I was unable to find an answer in the mailing list: I did a paired cortical thickness group analysis: mris_preproc --fsgd /home/paired.fsgd --target fsaverage --hemi lh --meas thickness --out lh.paired.00.mgh --paired-diff (smoothing) mri_glmfit --y lh.paired.05.mgh --fsgd diff.fsgd --osgm --surf fsaverage lh --cortex --glmdir lh.05_diff.glmdir I found an area of difference in cortical thickness and I would like to know the thickness values of this area for all of the input in paired.fsgd, not just the differences I get from the y.ocn.dat file. How do I extract thickness values from the lh.paired.00.mgh file using the label file of the significant cluster?

Re: [Freesurfer] label transformation to MNI space
Dear Doug, I have problem similar to this: I am trying to convert V1 labels from the Hinds method to volumes and transform them to MNI152 space for use in FSL. I tried using this command: mri_label2vol --label rh.v1.prob.label --reg $FREESURFER_HOME/average/mni152.register.dat --temp MNI152_T1_2mm.nii.gz --o rh_v1_prob.nii.gz --label-stat rh_v1_prob_stat.nii.gz ...but the output is not registered correctly. It seems to be shift downward as Linda described. Label conversion using the cmd mri_label2label --srclabel rh.v1.prob.label --s --regmethod surface --trglabel rh.v1.prob.new.label --hemi rh does not solve it. Any suggestions? Best regards, Anders Hougaard 2011/10/18 Douglas N Greve > The problem appears to be with the label itself.

Re: [Freesurfer] flipping surface data
Dear Doug, I would like to the same thing that Kelsi (as I read the post) asked about: For patients with a lesion in one hemisphere, I want to compare the hemispheres with lesions to the contralateral hemispheres without lesions. I think that your answer below is a recipe for comparing right and left hemispheres within subjects. In my case half of the patients have a lesion in the right hemisphere and the other half have a lesion in the left hemisphere. I guess I should register all of the hemispheres to the left hemisphere of fsaverage_sym, but how do I set up the analysis for doing a paired comparison of hemispheres with lesion vs hemispheres without?

[Freesurfer] Converting V1 labels to nifti
Dear Freesurfers, I would like to use V1 labels (created with the Hinds method) for a ROI-based analysis on data analyzed with FSL FEAT using FSL featquery. I have not run a full recon-all segmentation, only recon-all -s subjid -label-v1 I need to convert the labels to nifti volumes while registering to MNI standard space. I guess the right command would be something like mri_label2vol --label lh.v1.predict.label --reg register.dat --hemi lh --subject subject --o lh.v1.predict.label Is there a register.dat from the FSL feat directory that I could use for this? Anything else I need to add? Of course, I would like to keep the resulting volume probabilistic.

[Freesurfer] Retinotopy stimuli
Dear freesurfers, Which stimuli do you think provide the best retinotopic maps?

Re: [Freesurfer] Retinotopy stimuli
Hi all, Thank you very much! I did 2 runs of each of the stimuli I described in one session (I previously got some pretty decent maps from these data using the mrVista package from Stanford). I followed the retinotopy instructions from the FS wiki ( http://surfer.nmr.mgh.harvard.edu/fswiki/FsFastIndividualRetinotopyAnalysis) but the results did not make much sense. I guess I need to use some other commands or change some parameters in order to view reasonable eccentricity and polar angle maps. I have not managed to find any other documentation on how to do this. This is what my "raw angle" looks like: http://dl.dropbox.com/u/6981172/raw_angle.tif Best, Anders 2011/7/7 Jonathan Polimeni > > hi anders, > > the optimal set of stimulus parameters will depend somewhat on what > cortical area(s) you are trying to map and on the details of your > acquisition. in general, stimulating with both clockwise- and > counterclockwise-rotating wedges for polar angle mapping and with both > expanding and contracting rings for eccentricity mapping improves the > accuracy of the maps, and the proper analysis of this data is implemented > fsfast. the width of the wedge or the ring will depend on the cortical > area you are trying to stimulate, but you may want to consider a thinner > wedge. also, 8 Hz flickering has been shown to activate area V1 more > strongly than other frequencies, and smoothly moving stimuli can also > help. then, depending on your voxel size, field strength, coil array, > etc., you could include more cycles and may need to average together > multiple runs. > > marty, roger et al. have a few nice papers that i'd recommend that discuss > some of these details relating to phase-encoded retinotopic stimuli. > > Sereno & Tootell.
