write.group.morph.standard.sf: Reshape and write combined per-vertex data for a group to a single MGH file.

Description

Write morphometry data for a group into a single MGH or MGZ file. In neuroimaging, the first 3 dimensions in the resulting 4D volume file are space, and the 4th is the time/subject dimension.

Usage

write.group.morph.standard.sf(filepath, data)

Arguments

filepath

character string, path to the target file, should end with '.mgh' or '.mgz'.

data

numerical 2D matrix, with the rows identifying the subjects and the columns identifying the vertices.

Examples

if (FALSE) {
# create per-vertex data for 5 subjects.
mat = matrix(rnorm(5 * 163842, 3.0, 0.5), nrow=5, ncol = 163842);
fsbrain::write.group.morph.standard.sf("~/group_pvd.mgz", mat);
}
