getAtlasLabels: Find anatomical atlas labels.

In arf3DS4: Activated Region Fitting, fMRI data analysis (3D).

Description

getAtlasLabels finds anatomical atlas labels for a set of coordinates (either native ARF space or standard MNI space). It requires a working copy of FSL.

Usage

getAtlasLabels(coordinates, registration, coortype = c("arf", "mni"), 
 atlas = c("both", "Talairach", "HarvardOxford"), ...)

Arguments

coordinates	Matrix with three columns (x,y,z) containing coordinates of a region. Multiple regions are in the rows of the matrix.
registration	A "registration" object belonging to the data the coordinates are from (see registration).
coortype	In what coordinate space are the coordinates (ARF native or MNI space).
atlas	For which atlases should the labels be returned? Currently only 'talairach' and 'harvardOxford' are available.
...	Arguments passed to the atlas lookup functions (FSLDIR indicates the FSL directory, which is '1mm' or '2mm')

Details

getAtlasLabels only works with a working copy of a full FSL installation (>=4.1).

Value

Returns a list of length nrow(coordinates) with a talairach and/or a harvard slot containing the labels.
