[phenixbb] executing Phenix in a python script on a Windows OS

[Robert Oeffner]

Dear Muriel,

The file 
C:\Users\MG\Phenix\phenix-installer-1.19.1-4122-intel-windows-x86_64\phenix_env.bat 
should not be run from a python subprocess. It is only used once for 
initialising the pheinix environment in your command prompt so that you 
may start phenix.python, phenix.refine or any other phenix.some_command 
from there.

Once you have started a phenix.python session from a command prompt you 
then need to import various modules such as the phenix, iotbx, cctbx, 
etc in order to use functions available from these.

If you're not used to write and work with python scripts it's not 
productive use of time to write python scripts for phenix.refine. It may 
be easier to do what you want just using the command line interface of 
phenix.refine.

Regards,

Robert
