[Chimera-users] Unrecognized command: "minimize"

[Viachaslau Bernat]

Dear Chimera developers,

I've got a problem with scripting in chimera. By analogy with your 
example I've written a python script for geometry optimization of small 
library of ligands. In GUI mode all commands run smoothly as I type them 
into chimera command line. Nevertheless, when I try to run a script 
containing the same commands I get the error `unrecognized command: 
"minimize"`, no matter if I run it from GUI interface menu or with 
--nogui parameter.

Here is my testing script (test.py):

      import os
      import chimera
      from chimera import runCommand as rc
      from chimera import replyobj
      os.chdir("/home/viachaslau/sybyl/sublib/")
      fn = "lib1.mol2"
      rc("open " + fn)
      rc("miminize nsteps 70000 stepsize 0.001 interval 100 freeze none
    nogui true")
      rc("write format pdb 0 min/" + fn + ".pdb")
      rc("close all")
      rc("stop now")

And here is the output from Python:

    ~/sublib> ~/chimera/bin/chimera --nogui test.py
    Executing test.py...
    Opening lib1.mol2...
    UNQ1 opened

    Traceback (most recent call last):

         'Unrecognized command: "%s"' % cmd
    MidasError: Unrecognized command: "miminize"
    Error while processing test.py:

       File "/home/viachaslau/chimera/share/Midas/midas_text.py", line

         'Unrecognized command: "%s"' % cmd

    See reply log for Python traceback.

I run SUSE 11.3 as operating system and chimera is installed into ~/chimera/
I also tried to run commands row by row in IDLE window of chimera and 
found out that python suspends on runCommand("minimize ...") command
