External Email - Use Caution Hi all, I’m having some trouble getting an an accurate registration between an individual functional volume and MNI152 space. Presently, I’m using the commands: bbregister --s MNI152_FS --mov volumeInFunctional --reg mniDir/filename2mni.lta --init-fsl --bold mri_vol2vol --mov volumeInFunctional --reg mniDir/filename2mni.lta --fstarg --o ‘ mniDir/filename.nii --no-resample I’ve also tried using the strategy detailed here<https://mail.nmr.mgh.harvard.edu/pipermail//freesurfer/2010-October/016016.…>, without much luck (the registration was very distorted). Is there a different method for registration to MNI152 that yields more accurate results? Thanks very much for any suggestions! Best, Anna

transforming functional volumes to MNI without resampling
by David Beeler 07 May '18

07 May '18

External Email - Use Caution Hi, I'm trying to register and transform some raw functional data (108x108x72x175, 2mm iso voxels) to MNI space, while keeping the low res dimensions. I have tried: bbregister --s MNI152_FS --mov funcVol --reg func2mni.lta --init-fsl --bold mri_vol2vol --mov funcVol --reg func2mni.lta --o funcVolMNI --fstarg --no-resample --nearest mri_vol2vol --mov funcVol --reg func2mni.lta --o funcVolMNI --fstarg --no-resample And this looks pretty good, but not perfect... the functional data is oriented correctly but the brain seems to be a centimeter or two smaller in multiple dimensions, see: http://web.mit.edu/dsbeeler/www/images/bbregister-mni.png I'm not too surprised since the MNI brain is blurry and oddly round, but presumably there is a way to do this transformation more accurately. I've run mri_cvs_register for this subject using the --mni flag: mri_cvs_register --openmp 8 --mni --mov $subjID --outdir $mniDir And for other applications I use this m3z file to transform volumes between MNI orig.mgz and individual subject orig.mgz, but is there a way to use it to transform functional data to MNI space while keeping the functional dimensions? I could do: mri_vol2vol --mov funcVol --targ $SUBJECTS_DIR/$subjID/mri/orig.mgz --reg register.dof6.lta --nearest --o template-in-anat.nii.gz mri_vol2vol --noDefM3zPath --targ $SUBJECTS_DIR/$subjID/mri/orig.mgz --mov template-in-anat.nii.gz --m3z $mniDir/final_CVSmorph_tocvs_avg35_inMNI152.m3z --o template-in-MNI-m3z.nii.gz --nearest But not only is this unideal because it requires upsampling the functional data to 256x256x256, it also gets these funky wavy distortions: http://web.mit.edu/dsbeeler/www/images/m3z-mni.png Any thoughts are appreciated, thanks! -DB

Problems at exporting recon-all outputs
by Miguel Ángel Rivas Fernández 05 May '18

05 May '18

External Email - Use Caution Hi Freesurfer developers, After having executed the recon-all in several subjects I tried to export all measures of the Destrieux atlas (area, volume, curvind, foldind, gauscurv, meancurv, thickness and thicknesstd) but I got an error because in some variables only zeros appear and however, in the other variables I did obtain values when doing the export. I had the same error in some variables when exported the subcortical segmentation (aseg.stats) and the wm (wmparc.stats). Why do some variables appear without any value? Thanks in advance, Cheers, -- *Miguel Ángel Rivas Fernández*

Freeview surface annotation outline line thickness
by Kayle Sawyer 04 May '18

04 May '18

External Email - Use Caution The freeview flag "annot_outline=1" is great for viewing results for significant clusters from mri_glmfit-sim. Is there a way to make the outlines thicker? With the default thickness, the outlines are difficult to make out in a multipanel figure. (The "edgethickness=" flag specifies the slice intersection crosshair with the surface, not the annotation outline thickness.) Thanks, -Kayle

Re: [Freesurfer] Trouble getting git-annex files

External Email - Use Caution Hello, I need help recompiling dmri_train for Mac. It seems like the instructions in the Mac Developer’s don’t work. When I cd to the trc subdirectory and run make, I am told there is nothing to do. I tried editing the Makefile, adding bin_PROGRAMS = dmri_train, at which point I got a different error. I then uncommented some other lines in the Makefile and managed to start compiling dmri_train, but I’ve been getting a never-ending sequence of errors, essentially telling me that the compiler can’t find various dependencies (boost/program_options.h, itk*.h, etc.). I’ve tried running ./configure with various flags that disable or enable various build options, copying over .h files from other locations, adding -I <path> directives for the compiler in the Makefile, etc. etc. to no avail.
