Problem in building FreeSurfer from source
by Akio Yamamoto 16 May '12

16 May '12

I'm having a problem in building FreeSurfer from the source codes (both 'stable5' and 'release_5_1_0') downloaded from the CVS repository. When I run 'make', it stopped with the following error message: mri_convert.c:39:40: error: unwarpGradientNonlinearity.h: No such file or directory mri_convert.c: In function 'main': mri_convert.c:1158: error: 'unwarp_flag' undeclared (first use in this function) mri_convert.c:1158: error: (Each undeclared identifier is reported only once mri_convert.c:1158: error: for each function it appears in.) ...... I actually could not find the file "unwarpGradientNonlinearity.h" in the distribution, and am wondering if the open source distribution is confirmed to be successfully built without any modification. Are there additional things that I need to do before running 'make'? Or, is a newer version of the source code available? Thanks, Akio -- Akio Yamamoto Research Associate, The University of Tokyo

aseg.stats not matching up
by Joshua Lee 16 May '12

16 May '12

Suppose I were to open a subject aseg.mgz in tkmedit, and use the 3D fill tool to relabel the *entire* left hippocampus segmentation to 'MyNewImaginaryLabel'. If I then re-run the aseg stats, should the left hippocampus volume from the original aseg.stats be identical to the volume of MyImaginaryLabel in the newly generated aseg.stats? Every voxel from the prior label is now assigned to the new label; yet, I am getting different results (by about 100 voxels in the ones I've tried). The command Im using to recalculate: mri_segstats --seg /usr/local/freesurfer/subjects/s02/new_MRI/new/aseg.auto.mgz --sum /usr/local/freesurfer/subjects/s02/stats/NEWmethod1aseg_Hipp.stats --pv /usr/local/freesurfer/subjects/s02/mri/norm.mgz --excludeid 0 --brain-vol-from-seg --brainmask /usr/local/freesurfer/subjects/s02/mri/brainmask.mgz --in /usr/local/freesurfer/subjects/s02/mri/norm.mgz --in-intensity-name norm --in-intensity-units MR --etiv --surf-wm-vol --ctab /usr/local/freesurfer/8regions.txt --subject s02; Now if I were to relabel 'MyNewImaginaryLabel' to 'AthirdLabel', and again changing every voxel in 'MyNewImaginaryLabel' to the new label, the computed volumes do not change. This led me to suspect that aseg.mgz contains probability estimates at each voxel that are then subsequently overwritten by my tkmedits. However, per a previous conversation from a year ago or so with Bruce and also the relevant Freesurfer documentation this does not seem to be the case. Partial volume information is not contained within the aseg.mgz (right!?), but is computed by mri_segstats by comparing border voxels with intensities in the norm.mgz. So I am at a loss on why these should be different.

FsFastIndividual Retinotopy - Polar Only
by Daniel Cole 16 May '12

16 May '12

Hello, I have some questions regarding the FsFastIndividual pipeline. I hope you can take a look at the commands I have run and give me some insight into what the problem might potentially be. I have 5 rotating wedge stimuli runs 1. I set up my subject's directories according to the freesurfer tutorial powerpoint and declare my environmental variables using- <*export FREESURFER_HOME=/Volumes/RCBI/freesurfer* *export SUBJECTS_DIR=/Volumes/rcbiUsers/dcole/Retinotopy* *source $FREESURFER_HOME/SetUpFreeSurfer.sh*> Bold data renamed to f.nii.gz and placed into run folders (001, 002, etc) rtopy.par=" stimtype polar direction neg" 2. I then reconstruct the strucutural data using- <*recon-all -i /Volumes/rcbiUsers/dcole/Retinotopy/VG01/raw/VGP01_001.dcm -subjid VG01*> 3. I create the subjectname file, run preprocessing, and make the analysis files. <*preproc-sess -surface self lhrh -fwhm 5 -sf sessid -fsd bold* *mkanalysis-sess -analysis rtopy.self.lh -surface self lh -TR 1.2 -abblocked 38.4 -fsd bold -fwhm 5* *mkanalysis-sess -analysis rtopy.self.rh -surface self rh -TR 1.2 -abblocked 38.4 -fsd bold -fwhm 5*> 4. Then I run the analysis using- <*selxavg3-sess -analysis rtopy.self.lh -sf sessid* *selxavg3-sess -analysis rtopy.self.lh -sf sessid*> ~This step was giving me an error until I added "faux" eccentricity run folders with runs 1-5 functional data copied and rtopy.par files with stimtype eccen. Rerunning these 2 steps with the faux eccentricity data fixed the error message. 5. Create occipital patch with (http://www.alivelearn.net/?p=65) as guideline. Flatten patch using- <*mris_flatten -w 0 -distances 20 7 lh.occip.patch.3d lh.occip.patch.flat* *mris_flatten -w 0 -distances 20 7 rh.occip.patch.3d rh.occip.patch.flat*> And create fieldsign map using- <*fieldsign-sess -a rtopy.self.lh -occip -sf sessid* *fieldsign-sess -a rtopy.self.rh -occip -sf sessid*> ~Error that analysis isn't retinotopy (because I used -abblocked), retrying step 3 with -retinotopy allowed me to create the fieldsign map. --- For the -abblocked and -retinotopy analysis I am able to look at the results using <*tksurfer-sess -a rtopy.self.lh -sf sessid*>*.* My questions are: - Should I be using -abblocked or -retinotopy for a polar only design? - Is it ok to create "faux" eccentricity folders and then only look at the polar data? - Why is it for either of these analyses I can't view the angle map using <*tksurfer-sess -a rtopy.self.?h -s sessid -map angle*>? In fact the angle file is not created. Thanks so much for your time and help. Daniel * * -- Daniel Cole University of Rochester Brain and Cognitive Sciences dcole10(a)u.rochester.edu

Flip brain
by Tadeu Kubo 16 May '12

16 May '12

Dear FS experts, How can I flip hemispheres? I read the mail list and Doug said that (2010): The problem with this is that you will get different results when you use the left hemi and the right-flipped-to-left hemi as compared to the right hemi and the left-flipped-to-right hemi. You'll actually get different areas that appear to be significant. This is because the right-flipped-to-left is registered to the left template target and it does not register as well as the left registered to the left template target (and the same in the other direction). I'm sure it means something, but I don't know how to interpret it. doug I'm specially interesting because we're studying MTS. The status of this procedure remains the same or it is possible to do it ? Thank you, Tadeu

Different values for cortical thickness
by Nooshin Zadeh 16 May '12

16 May '12

Dear Freesurfer Friends I have a question about cortical thickness. I do not understand why these commands give us DIFFERENT values for "average cortical thickness". Can you please let me know if you have any idea. Thanks a lot mris_anatomical_stats N2207 lh number of vertices = 157417 total surface area = 102378 mm^2 total gray matter volume = 234251 mm^3 average cortical thickness = 2.080 mm +- 0.889 mm average integrated rectified mean curvature = 0.198 average integrated rectified Gaussian curvature = 0.223 folding index = 13893 intrinsic curvature index = 1137.3 mris_anatomical_stats -t N2207/label/lh.cortex.label -b N2207 lh same as mris_anatomical_stats -t -b N2207 lh number of vertices = 157417 total surface area = 102378 mm^2 total gray matter volume = 0 mm^3 average cortical thickness = 0.000 mm +- 0.000 mm average integrated rectified mean curvature = 0.198 average integrated rectified Gaussian curvature = 0.223 folding index = 13893 intrinsic curvature index = 1137.3

Thanks Bruce! Those are the main questions now (not only to V1, but also to the rest of the Brodmann areas). I really want to be sure where the measures come from. I want that the different measures (i.e. cortical thickness and area are really from the same region in the cortex), to know what should be exported to run the statistical analysis. At some point the list email was not in Cc anymore... Here it goes to the list too. Thank you so much for your help!

vertex-wise correlation
by Kemmotsu, Nobuko 15 May '12

15 May '12

Dear Freesurfer experts, I have fMRI data that are processed in AFNI that I would like to examine the relationship with cortical thickness measures. In particular, I am interested in vertex-wise correlation of thickness and BOLD % signal change. The problem is I am new to Freesurfer. So far I have found that the program "mri_glmfit" appears to be able to handle vertex-wise regressor, with the -pvr option. First, does this enable me to do vertex-wise bivariate correlation? Second, if so, it appears that the input files need to be concatenated (or stacked??), and for FreeSurfer measures, "mris_preproc" seems to take care of it. But, how can I stack/concatenate the afni-generated files (which are registered to and mapped on to each individual's surface that are in .mgh format)?? I appreciate any input you may have- -- Nobuko Kemmotsu, Ph.D. University of California, San Diego
