[Freesurfer] FSGD error: class Input not defined

Dear Freesurfer experts, I am trying to perform the resting state fMRI analysis as in: http://surfer.nmr.mgh.harvard.edu/fswiki/FsFastFunctionalConnectivityWalkthrough I got stuck with the STEP8, when I tried to use my own fsgd file. I tried to test for two group difference, no covariance as in:

Re: [Freesurfer] Yeo 2011 Functional Cortical Parcellations

Hi Bronwyn, You raise a good point. You can consider creating a cortical mask using aparc+aseg.mgz and use that to mask the networks. However, another approach (which might be more accurate) is to take cortical networks in fsaverage space and transform to your subject's surface and then

[Freesurfer] patch error

Hello all, I'm trying to make a patch and have run into the 'bad vertex' error. It's come up a few times on the listserv, but I never saw a public resolution. One possible source of errors is that I had to do a manual correction in FreeView, including a 'remove intersections' in FreeView.

Re: [Freesurfer] registering to fsaverage

thanks Bruce - I had found that option for my fsaverage maps and it worked. What about if I am importing probability maps formed as .mnc and creating overlays from them? The percentages seem to be very odd for min and max threshold. Trisanna -- Ph.D. Candidate McGill University Integrated

Re: [Freesurfer] registering to fsaverage

Hi Trisanna if you are using mri_average you can give it -p as the first argument and it will compute a percent at the end Bruce On Wed, 22 Jun 2016, Trisanna Sprung-Much wrote: Hi Bruce Is there is a way to set the probability of an overlay between 0 and 1? Would this have to be done

Re: [Freesurfer] Any updates on recon-all GPU support?

Hi Richards, Thanks for the very quick reply. Good to know that someone has successfully compiled GPU binaries for newer CUDA versions. I took a quick look at the developer's guide for building the cuda binaries from source, but it seems like a very involved process? Do your compiled

Hi Bruce Is there is a way to set the probability of an overlay between 0 and 1? Would this have to be done when creating the overlay using mri_vol2surf? thanks Trisanna -- Ph.D. Candidate McGill University Integrated Program in Neuroscience Psychology On Mon, Jun 20, 2016 at 12:11 PM, Bruce

[Freesurfer] Any updates on recon-all GPU support?

Anyone manage to successfully configure recon-all to run with -use-gpu for recent cuda toolkit versions? I realize cuda support has ceased over the past few years for Freesurfer, but have there been any successful builds for CUDA toolkit versions 6 and up? I am currently looking to configure

I should add that we're running tkmedit using xvfb since the process is automated and runs without a physical screen. Flavin > On Jun 22, 2016, at 4:15 PM, Flavin, John wrote: > > Hi all, > > I run the pipelines for the CNDA and various other XNAT installations. We >

[Freesurfer] X11 / mesa update broke tkmedit snapshots

Hi all, I run the pipelines for the CNDA and various other XNAT installations. We recently updated some of our packages, and our Freesurfer snapshots (generated with tkmedit using a tcl script) have broken. We're on Centos 6.8. The package that seems to cause the breakage is one of the mesa

Re: [Freesurfer] Quality control with different pipelines

Thank you Michael! So - just to be super sure I'm on the same page here. If I've run a subject using 5.3 I take that same subject directory (after backing it up somewhere) and then run the dev version of recon-all with the -all flag. After it's completed I (should - contingent on checking again

Re: [Freesurfer] Quality control with different pipelines

Hi, You can simply rerun 'recon-all -all’ on top of your already processed/edited subject, and it will respect your previous edits.  Of course, it is a good idea to still review/QC the results afterwards, to make sure that the outcome of those edits is satisfactory under the new FS

[Freesurfer] Quality control with different pipelines

Hi everyone, I processed and edited 300 participants for our study using Freesurfer 5.3 and I'd like to move to using the dev version that's currently available because we have a bunch more data that's been collected and I think it does a better job. (This question also applies to moving to v 6
