[Chimera-users] "ligand" category for selection

[Hurt, Darrell (NIH/NIAID) [E]]

Hi Tom,

Oh yes, I forgot about the "try" command. I'm still pretty new at Python. That's the perfect way to do it.

Thanks!
Darrell

Hi Darrell,

  I’m not sure what Python code you are using that produces the “No atoms specified” error.  Probably you are running a Chimera command.  You can catch that error in Python and ignore it with code like

from Commands import CommandError
try:
   # Your ligand selection code here
except CommandError:
    pass  # Got an error, ignore it

Hi Chimera friends,
I'm trying to use the attached MOL file (dopamine) in Chimera and I want to run a Python script on it. My script does some things to the molecule using selection categories. I'm trying to select this molecule as "ligand", but I get a "No atoms specified" error.
Alternatively, is there a way in Python to ignore the error if I get it and keep processing the rest of the script?
Thanks,
Darrell
