= Name =
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||
