Arguments

header

Header of the mgh datastructure, as returned by read.fs.mgh.

Value

character string of length 3, one uppercase letter per axis. Each of the three position is a letter from the alphabet: 'LRISAP?'. The meaning is 'L' for left, 'R' for right, 'I' for inferior, 'S' for superior, 'P' for posterior, 'A' for anterior. If the direction cannot be computed, all three characters are '?' for unknown. Of course, each axis ('L/R', 'I/S', 'A/P') is only represented once in the string.
