Region labels disappear after atlas2region() for certain regions

[Michael-Sun]

On such regions such as NPS 'rLOC' and SIIPS 'L-TP', atlas2region () doesn't work for certain regions.

Example:

Step 1: Download NPSneg and SIIPSneg from this link: https://www.notion.so/Generate-and-write-out-NPS-and-SIIPS-ROI-Subregion-Objects-8eb8e2f3bee34dd2bf8bc0477ef6e3ec

Step 2:
load('npsneg.mat');
load('siipsneg.mat');
at=npsneg;
atlas2region(at.select_atlas_subset({'rLOC'}))
at=siipsneg;
atlas2region(at.select_atlas_subset({'L-TP'}))
