Hello Freesurfers

I'm trying to do volumetric reconstruction, i already have done this but. i wanted to see if for the same subject, with different directions of slices i have the same result, and obviously i had different results of volumetric measures. i have used the sequence FSPGR T1 ponderation, with the same parameters for both data acquisition; with voxel 1 mm3, but the direction is changed in both studies axial and sagittal. Both studies are in *.dcm format, and i used the next command for convert dicom to .mgz and after to apply recon-all process:

0. mri_convert firstdicom.dcm 001.mgz 

I would like to know why would i have this problem?

There is some specific slice direction for this kind of study which is suitable ?

I'm interested in cerebellum volumetric information. I attached my results for volumetry.

Cheers
