You can run something like mri_convert nopvc.nii.gz --ascii nopvc.dat This will give you a text file To put a bunch together across subject, you can run something like mri_concat */nopvc.nii.gz --o all.nopvc.nii.gz Then do the same trick as above.

Hi experts,

As stated in the subject, how to convert "nopvc.nii.gz" generated by "mri_gtmpvc" to a format like "gtm.stats.dat"? Moreover, how to consolidate all "gtm.stats.dat"'s PVC uptake values of ROIs from different subjects in one spreadsheet? Is there any existing command to do that?

Thanks, Angel
