Hello, Freesurfer team 

This is Wei Shao, I was trying to convert the freesurfer automatic segmentation of the hippocampus subfield into native space so I can compare it with the manual segmentation. 

Here is the command:

mri_label2vol --seg lh.hippoAmygLabels-BAYXXXXX-T2.v21.CA.mgz --temp rawavg.mgz --o lh.hippo-BAYXXXXX.mgz --regheader aseg.mgz

1 Could you tell me which files I should use in terms of the temp and regheader flag.

2 the manual segmentation based on T2 image, do I need to use the same T2 image as the overlaid image when it comes to Freeview? I think the nu.mgz is T1 image, could you tell me where I can find the T2 image accordingly?

3 do you know any command that can help me to check the information of the .mgz file like the 3dinfo command?

I really appreciate your help, Thanks.

Best,

Wei
