[Freesurfer] Cuda version > 5.0

Dear FS list, we just got a really nice graphics card (Quadro P6000) that we also would like to use to speed up recon-all, preferably for running high-res data with FS version 6. Now we know that in the precompiled FS version 6 it still looks for cuda 5.0, but it seems like some people have

looks like the acquisition is not what you would need to run FreeSurfer on. Looking at the log I think your input is a T2-weighted image (we require a T1) with a slice thickness of 9mm (we require all voxel dimensions to be <=1.5mm or so) cheers Bruce On Thu, 8 Feb 2018, Z Hessam wrote:

[Freesurfer] smoothing command line- LGI

Hi, I am interested in looking at between-group differences in in LGI on Qdec (I will look at surface area as well later). I have a question regarding the smoothing stage. My recon-all for all subjects has completed, and I have LGI values for each subject. For smoothing, I was going to run the

Dear Bruce, Many thanks for you kind answer. I sampled the perirhinal roi label into the volume using the suggested command line: "mri_label2vol --subject s6904 --fill-ribbon --label lh.perirhinal.label --o lh.perirhinal.volume.nii --hemi lh --identity". The obtained mask seems to cover well

I agree that it looks like a topological defect that is fixed incorrectly. We can't tell from looking at the image of one slice though. If you gzip, tar and ftp the subject to us we will take a look cheers Bruce On Thu, 8 Feb 2018, Arsenije Subotic wrote: Hi Doug, I’ve

2018-02-08 Thread Bruce Fischl
Hi Mohamed it depends on how you computed it. I believe that the one in the exvivo.stats file computes it directly from the surfaces (i.e. sum of the volumes of the tetrahedra or something like that). If you sample it into the volume and add up voxels you will get discretization artifacts
