mri_label_volume - get various volume stats
Synopsis
mri_label_volume [options] <volume> <label 1> <label 2> ...
Arguments
Positional Arguments
volume |
the .mgz file, eg. aseg.mgz |
label 1 |
the label number, eg. 17 (left hippocampus) |
label 2 |
another label number, eg. 53 (right hippocampus) |
... |
more label numbers |
Optional Flagged Arguments
-pv <fname> |
compute partial volume effects using intensity volume <fname> |
-icv <fname> |
normalize by the intracranial volume in <fname> |
-s <subject> |
output in spreadsheet mode, including <subject> name in file |
-a |
compute volume of all non-zero voxels (e.g. for computing brain volume) |
-t <in> <out> |
replace label <in> with label <out>. Useful for compute e.g. whole hippo vol |
-b <brain vol> |
compute the brain volume from <brain vol> and normalize by it |
-p |
compute volume as a % of all non-zero labels |
-l <fname> |
log results to <fname> |
-atlas_icv <fname> <scalefactor> |
specify LTA or XFM atlas transform file and scale factor to use for ICV correction (c.f. Buckner et al. 2004) |
-eTIV <fname> <scalefactor> |
same as -atlas_icv |
-eTIV_matdat <fname> <scalefactor> <subject> |
same as -eTIV, and generate matlab data appending <subject> to structure |
