Hi,
I have used many times successfully this cpptraj script:trajin pczn_wt_Final.mdcrd 200 10000000 1
# Average the trajectory.

but with version 15 it not works anymore. I haven't problems with the prmtop file and tested above script on several trajectories. What was changed?The error is:[reference Avg.rst7.1 [avg]]
Error: reference: Could not set up trajectory.
1 errors encountered reading input.
This is the full output:
