I cannot replicate this, eg
In matlab a = fast_vol2mat(MRIread('gtm.nii.gz')); a(1:10) Columns 1 through 7 0.7957 1.0565 1.5711 1.7842 1.8625 1.9539 1.2499 Columns 8 through 10 1.3188 1.4063 1.2536

You can see that the values match

Dear Freesurfer experts, I have compared the PVC uptake values of gtm.stats with the values of gtm.nii.gz with the function load_nii in matlab. I noted that values in matlab are reversed, i. e., the first value in gtm.stats matches with the last value in gtm.nii.gz and so on.
Could you confirm me that nopvc.nii.gz values are also reversed when loaded with load_nii in matlab? I have no way to check this. Thank you in advance. Best, Marina
