Dear experts,
I hope this email finds you well. I run the pvc correction with mri_gtmpvc for subjects data obtained with two different PET tracers. In gtm.stats.dat, for every subject and every region, the number of voxels evaluated for amyloid tracer is approximately twice the volume evaluated for the second tracer. I'd expect that the volume of a region for the same subject doesn't change with the tracer.
Do you think this error can result from previous errors in the analysis? Or is it in some way plausible?
Thank you for your patience, Federica
