After some investigation, I found that that command will not work. You can run it in the normal way, and then run mri_vol2vol --mov rbv.nii.gz --targ pet.nii.gz --regheader --fill-average This will average all the rbv voxels that fall into a pet voxel (or you could use --interp

I tried the following, but the program seems to seg fault. No output files are created. Please help! Thank you. Alternatively, is there a way to generate the "nopvc" image in RBV space? Thanks! *>>mri_gtmpvc --i pet.nii.gz --reg pet2mri.lta --psf 6 --seg gtmseg.mgz --no-reduce-fov --o pvcout*

It is not set up to do it this way, but there is a work-around. Run mri_gtmpvc without --rbv but with --no-reduce-fov, then run it again specifying the gtmpvcoutput/seg/seg.nii.gz file as the segmentation and --regheader instead of --reg. On 12/05/2016 11:52 AM, SudEEpti wrote: > Hello, > >

[Freesurfer] RBV PVC: Saving output file before upsampling

2016-12-05 Thread SudEEpti
Hello, Is there a way to save the PVC (RBV) output in native PET resolution, before upsampling? Would you also be able to share the command that is used for upsampling? I would like to play with a different type of interpolation. Thank you very much. Su
