get.volume.from.roi: Volume of a region of interest (RoI)

Description

The get.volume.from.roi function extracts the volume incm^3ascii of one or more RoI, from the $roi.info of the "struct" class object.

Usage

get.volume.from.roi(struct, roi.name = NULL, roi.sname = NULL, roi.idx = NULL)

Value

Returns a vector of the volumes in cm^3ascii of the requested RoI.

Arguments

struct

"struct" class object.

roi.name

Vector of exact names of the RoI in the struct object. By default roi.name = NULL. See Details.

roi.sname

Vector of names or parts of names of the RoI in the struct object. By default roi.sname = NULL. See Details.

roi.idx

Vector of indices of the RoI that belong to the struct object. By default roi.idx = NULL. See Details.

If roi.name, roi.sname, and roi.idx are all set to NULL, all RoI are selected.
