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

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 On 02-03-2021 16:36, Muriel Gelin wrote:

Here is what I have:

--------------------------------------------------------------------------------

In python:

source = subprocess.Popen(str(r"C:\Users\MG\Phenix\phenix-installer-1.19.1-4122-intel-windows-x86_64\phenix_env.bat"), stdin=subprocess.PIPE, stdout=subprocess.PIPE, shell=True)

phenix.refine Traceback (most recent call last):   File "<stdin>", line 1, in <module> NameError: name 'phenix' is not defined py phenix.refine   File "<stdin>", line 1     py phenix.refine        ^

If somebody see what is the problem. I'm afraid I am stuck ...

Thank you all.

Dear Bernhard,

Thank you for your answer.

Executing phenix_env.bat in Windows command prompt works well, since I can then execute phenix.refine in the prompt.

So I tried to add in my python script something like that: source = subprocess.Popen(my_path\phenix_env.bat, stdin=subprocess.PIPE, stdout=subprocess.PIPE,                               stderr=subprocess.PIPE) Unfortunately, it doesn't work. I suppose the prompt environment is not modified.

Do you know how to do that in my python script so that I can then execute something like: xtriage = subprocess.Popen(["phenix.xtriage", my_mtz, "parameters.reporting.log=" + "xtriage.log")],                                stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE)

Thank you for you help.

Muriel

Here is what I did:

Install phenix

make a batch command in your path (eg phx.bat) that executes the environment setup, eg. C:\Phenix\phenix-installer-1.19-4092-intel-windows-x86_64\phenix_env.bat

Open terminal, execute that batch (modify as you like), and there you go

c:\data\Dropbox\Refinements\5okl>phenix.refine Usage: phenix.refine [options] [reflection_file] [pdb_file] [parameter_file] ....

Best, BR

Dear Phenix community,

I wrote a python script to automate the processing of our data with Phenix. I'm not a developer by profession, but a crystallographer, and write scripts usually under Linux. My colleagues working under Windows asked me to share my script.

I managed to run a simple python script under windows, no problem. But for a script that executes Phenix, it's not so easy (for me).

Under Linux, I manage to source phenix_env.csh, but under Windows what is the command to setup Phenix  in order to simply use phenix.refine or phenix.xtriage in my script?

All I can find is this page https://www.mrc-lmb.cam.ac.uk/public/xtal/doc/phenix/install-setup-run.html

but I don't think it answers my question.

Thank you in advance for your help!

Muriel
