Hi,

I tried ART with my mouse resting-state data. The quality of the dataset is good by observation. However, I got the error message after running ART:

======================
Session 1 global statistics - mean: 1466.0047 stdv: 1.0000
Outlier detection: 0 identified outliers

Statistics of movement data:

======================

I checked and found that empty outlier detection may cause the problem. Is it a bug or what? May I know how I can fix it?
