[Freesurfer] question about voxel size

Hi, I'm looking at a aparc.stats file. I noticed that VoxelVolume is 1 mm^3. However for this patient the voxel size was 0.9 x 0.9 x 1 mm^3 in acquisition. Actually, in the aparc.stats file Nvoxel = Volume_mm3 for each structure. I would like to understand whether the voxel size was resized from the acquisition value to 1 mm^3 and the result is ok or the voxel size reported in aparc.stats is uncorrect and I have to rescale the values for the correct voxel size. Actually the results are quite strange, in particular the intracranial volume is quite large and if I rescale for the above value the result is more similar to our past patients.

Thanks
