Determine the sizes of the CIFTI matrix dimensions.

Description

The CIFTI-2 matrix dimensions 0, 1, ... are stored in the dim field of the NIFTI-2 header, starting at its 6th entry (R index vectors are 1-based, so matrix dimension 0 is entry 6). The dimension order in the XML refers to matrix dimensions, so a MatrixIndicesMap with AppliesToMatrixDimension="0" describes the 6th entry of dim.

Usage

cifti.matrix.dim.sizes(niiheader, filepath = "")

Arguments

niiheader	the NIFTI-2 header of the file, required to determine the sizes of the matrix dimensions.
filepath	character string, the path of the file the XML was read from. Only used in error messages.

Value

integer vector, the sizes of the matrix dimensions.
