Layer-class


A class used for displaying 2D images with color maps


A collection of data structures that represent
volumetric brain imaging data. The focus is on basic data handling for 3D
and 4D neuroimaging data. In addition, there are function to read and write
NIFTI files and limited support for reading AFNI files.
