[ase-users] error with ag

[pgmoses]

Hi everybody

ag used to work like at charm, but I updated it today and now I get the
following error when trying to read a trajectory file
ag dyn_run2.traj 
Traceback (most recent call last):
  File "/Users/moses/ase/tools/ag", line 118, in <module>
    run(opt, args)
  File "/Users/moses/ase/tools/ag", line 82, in run

An exception occurred!  Please report the issue to
ase-developers at listserv.fysik.dtu.dk - thanks!  Please also report this if
it was a user error, so that a better error message can be provided
next time.


Any ideas on what is wrong would be much appreciated.
