On the freesurfer wiki, it says that recon-all can be done with DICOM inputs in addition to mgz inputs.
In doing recon-all using DICOM or mgz (created via unpacksdcmdir), the volumetric values obtained using mris_volume and mris_wm_volume are different.
For example in one subject, with DICOM inputs: pial 505865 and white matter volume 166713. with mgz inputs: pial 510322 and white matter volume 167030.
The white matter seems to be fairly close but the pial volume is off by nearly 4000.
Can someone explain why there is this difference and which value we should believe?
Thanks, Jennifer
