Check if object is a factor vector of subcortical structures.This is a helper
function for is.xifti.
is.subcort_labs(x)The putative factor vector of brain substructures.
Logical. Is x a factor vector of subcortical
structures?
xifti$meta$subcort$labels is a factor with the following levels:
Cortex-L
Cortex-R
Accumbens-L
Accumbens-R
Amygdala-L
Amygdala-R
Brain Stem
Caudate-L
Caudate-R
Cerebellum-L
Cerebellum-R
Diencephalon-L
Diencephalon-R
Hippocampus-L
Hippocampus-R
Pallidum-L
Pallidum-R
Putamen-L
Putamen-R
Thalamus-L
Thalamus-R
These correspond to the same structures as given by
ft_read_cifti in the cifti-matlab MATLAB toolbox.
Requirements: see the "Label Levels" section for the expected factor levels.
