Read vertex-wise brain surface data from a GIFTI file. The file must be a GIFTI *func* file (not a GIFTI *surf* file containing a mesh, use read_nisurface for loading GIFTI surf files).
read.fs.morph.gii(filepath, element_index = 1L)| filepath, | string. Full path to the input GIFTI file. |
|---|---|
| element_index | integer, the element to load in case the GIFTI file containes several datasets (usually time series). Defaults to the first element, 1L. |
data, vector of double or integer. The brain morphometry data, one value per vertex. The data type depends on the data type in the file.
This function requires the `gifti` package, which is an optional dependency, to be installed. It also assumes that the dataset contains a vector or a matrix/array in which all dimensions except for 1 are empty.
