In ciftiTools: Tools for Reading, Writing, Viewing and Manipulating CIFTI Files

Validate a factor vector of subcortical labels

Description

Check if object is a factor vector of subcortical structures.This is a helper function for is.xifti.

Usage

is.subcort_labs(x)

Arguments

x	The putative factor vector of brain substructures.

Details

Requirements: see the "Label Levels" section for the expected factor levels.

Value

Logical. Is x a factor vector of subcortical structures?

Label Levels

xifti$meta$subcort$labels is a factor with the following levels:

1. Cortex-L

2. Cortex-R

3. Accumbens-L

4. Accumbens-R

5. Amygdala-L

6. Amygdala-R

7. Brain Stem

8. Caudate-L

9. Caudate-R

10. Cerebellum-L

11. Cerebellum-R

12. Diencephalon-L

13. Diencephalon-R

14. Hippocampus-L

15. Hippocampus-R

16. Pallidum-L

17. Pallidum-R

18. Putamen-L

19. Putamen-R

20. Thalamus-L

21. Thalamus-R

These correspond to the same structures as given by ft_read_cifti in the cifti-matlab MATLAB toolbox. Note that the first two levels (left and right cortex) are not used.
