[gmx-users] amber2xtc.py error

[Albert]

hello:

   I am trying to use amber2xtc.py script to convert Amber MD system 
into gromacs format by command:

python amber2xtc.py npt3.mdcrd apo.prmtop . *.rst md_gromacs

however, I got the following messages

--------------log--------------------
  USAGE : python amber2xtc.py AMBERCRD AMBERTOP TRAJDIR TRAJPATTERN 
OUTPUTPREFIX
       Example : python amber2xtc.py mdcrd.crd mdcrd.top md *.x.gz 
md_gromacs
       Note that the AmberCrd can also be a PDB file.

Will convert the following files :
['m1.rst']
currently converting m1.rst
ls: cannot access *.pdb.*: No such file or directory
--------------------------------------

I am wondering how to fix this problem?

thank you very much
A.
