I have two questions"
1. the type of aparc+aseg.mgz file is INT(1). after save_mgh(v,
'aparc+aseg82regions.mgz',M,mr); I find the type of
aparc+aseg82regions.mgz is FLOAT (3). How to save aparc+aseg82regions.mgz
file in INT ?
2. I want to convert the aparc+aseg82regions.mgz to .nii file (in native
space)
I use the following command lines:
mri_label2vol --seg aparc+aseg82regions.mgz --temp rawavg.mgz --o
aparc+aseg82regions-rawavg.mgz --regheader aparc+aseg82regions.mgz
mri_convert -odt int aparc+aseg82regions-rawavg.mgz
aparc+aseg82regions-rawavg.nii
after these, I found the dimension is changed from 256*256*256 to
176*204*200.
Volume information for aparc+aseg82regions.mgz
type: MGH
dimensions: 256 x 256 x 256
voxel sizes: 1.0000, 1.0000, 1.0000
type: FLOAT (3)
fov: 256.000
dof: 1
Volume information for aparc+aseg82regions-rawavg.mgz
type: MGH
dimensions: 176 x 204 x 200
voxel sizes: 1.0000, 1.0000, 1.0000
type: INT (1)
fov: 204.000
dof: 0
Volume information for aparc+aseg82regions-rawavg.nii
type: nii
dimensions: 176 x 204 x 200
voxel sizes: 1.0000, 1.0000, 1.0000
type: INT (1)
fov: 176.000
dof: 0
I guess I must have done something wrong. But I can not figure out.
Best,
Jinsong
