Hi Doug,
Thanks for you quick response. Here is some info about the command line and output. ----------------------- $Id: mri_gtmpvc.c,v 1.69.2.1 2016/07/08 19:50:25 zkaufman Exp $ setenv SUBJECTS_DIR $SUBJECTS_DIR mri_gtmpvc --auto-mask 11 .001 --mgx .25 --lgtm --threads 8 --seg gtmseg.mgz --no-rescale --save-input --i $PET_DIR/cr_early_MeanCPS.nii --reg $PET_DIR/reg.lta --psf 6 --o $PET_DIR/pvc.psf06 --default-seg-merge sysname Linux hostname rincewind.nmr.mgh.harvard.edu machine x86_64 user clois vgthresh 0.001000 nReplace 18 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 Loading seg for gtm $SUBJECTS_DIR/mri/gtmseg.mgz Loading ctab $SUBJECTS_DIR/gtmseg.ctab Reading $SUBJECTS_DIR/mri/gtmseg.lta Failed tissue type check --------------------
I am including a couple of screenshots, as the error seems to be related to the subject's anatomy. After running the initial recon-all, there was a big whole in the wm.mgz (and the surfaces were wrong and excluded a big portion of the brain), so we filled it with wm voxels. The surfaces look now fine and there is no whole in the wm.mgz , but that has not solved the 'Failed tissue type' problem. Is there a more appropriate way to edit this case, so that we are able to run the pvc?
Let me know if this helps or you need any additional information.
Many thanks in advance, Cristina ________________________________ From: freesurfer-bounces@nmr.mgh.harvard.edu freesurfer-bounces@nmr.mgh.harvard.edu on behalf of Greve, Douglas N.,Ph.D. DGREVE@mgh.harvard.edu Sent: Monday, July 1, 2019 6:22 PM To: freesurfer@nmr.mgh.harvard.edu Subject: Re: [Freesurfer] mri_gtmpvc -- Failed tissue type check
Hi Cristina, can you send more info? Eg, your command line and terminal output. Do you do anything special (eg, your own annotation)?

I am having trouble with one subject's PVC (we process many cases and never had this issue before). When running mri_gtmpvc I get a 'Failed tissue type check' error.
I've seen that other people have reported similar errors in the past, but I haven't found any advice on how to trouble-shoot this. We have longitudinal PET data with two tracers for this subject, so it is very important for us to get this fixed. Any advice?
Thank you, Cristina
