Bug? Test failed on the branch feature-cna

Hi,
Several test codes related to NMA module failed to pass on the branch feature-cna. (See following error message. )
Note that these errors were not observed on the master branch!
I will continue to figure it out what's going wrong...
Testing aa2mass() : .1.
Testing atom mass functions : 23..456
