Steve,

In the last version, i got the following errors when i wanted to invoke atom velocity. With previous version, this worked.

variable CX atom (vx[]*(c_KE[]+c_PE[]))
compute Jcx all reduce sum v_CX

lammps gave me: “ERROR: Empty brackets in input command”

how to fix this issue?

cheers,

Ajing
