Hi Dan,


 The attached file is the cpptraj.out which was generated.

Thank you for your help.


Best wishes,

In my experience this either happens when not enough atoms are
selected (so diagonalization of the covariance matrix fails) or you
have corrupted coordinates. It would help to see the complete cpptraj
