Some folks were having issues getting CCTBX to work.  Here's one solution.


I hesitated to post this because I thought someone would have a more elegant solution, but I have got the draw_cell/symmops scripts working
Create a [https://repo.continuum.io/miniconda/ conda] environment with [https://anaconda.org/schrodinger/pymol schrodinger::pymol] and [https://anaconda.org/conda-forge/cctbx-base conda-forge::cctbx-base].
on windows with cctbx. I have had it working with all versions of PyMOL including the latest betas. I install PyMOL as usual in '''C:\Program
Files\Delano Scientific\PyMOL'''. I also got hold of python 2.4.1 [http://www.python.org/ftp/python/2.4.1/python-2.4.1.msi Python 2.4.1] and cctbx
[http://cci.lbl.gov/cctbx_build/results/2005_08_18_0201/cctbx_win_xp_py24_pre.exe CCTBX For Windows With Python 2.4] and installed them to '''C:\python24''' and ''''C:\cctbx_build''' & '''C:\cctbx_sources''', respectively.


In order to get things working together, I launch PyMOL with the following batch file:
On Linux and Windows:


<pre>
<syntaxhighlight lang="bash">conda create -n env1 schrodinger::pymol conda-forge::cctbx-base</syntaxhighlight>
@ECHO off

Just save as '''PyMOL.bat''' and run it (this is basically the cctbx '''setpaths.bat''' with a pymol command tagged on the end). I hope this helps.

This page describes how to use the Computational Crystallography Toolbox (cctbx) with PyMOL.

cctbx and PyMOL need to be compiled with the same Python distribution, otherwise they won't be compatible.

Incentive PyMOL

Create a conda environment with schrodinger::pymol and conda-forge::cctbx-base.

On Linux and Windows: 

conda create -n env1 schrodinger::pymol conda-forge::cctbx-base

On macOS, you also need schrodinger::tk and XQuartz: 

conda create -n env1 schrodinger::pymol conda-forge::cctbx-base schrodinger::tk

Open-Source PyMOL

See CCTBX-fedora32.
