I have tried making a chimerax module that can be installed in any Python (with the right version for binary compatibility) where all its Python capabilities can be used without needing the application user interface. But we have not distributed that, it has lots of problems. We have put it into two grant proposals to get funding for it but one proposal was not funded and the other we are still waiting to hear about.</div><div class=""><br class=""></div><div class=""> In theory it shouldn't be hard to reuse specific parts of ChimeraX, for instance reading mmCIF files.

ChimeraX contains hundreds of Python modules, so how will you figure out which ones you need? The easy solution is to take them all. But there are more problems, because the ChimeraX application initializes many of the modules, for instance, letting the atomic data structures module know where the residue template files are located. So you also need to figure that out. These many obstacles are why we proposed funding to make the code more usable without running the ChimeraX application -- it will be a good bit of work.</div><div class=""><br class=""></div><div class=""> So the standard solution is instead to just run your processing scripts with the ChimeraX application from the command-line</div><div class=""><br class=""></div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>chimerax --nogui myscript.py</div><div class=""><br class=""></div><div class=""> For compiling ChimeraX you must be using old ChimeraX source code (your example is fetching Python 3.7 but ChimeraX has used Python 3.8 for the last 9 months). The current ChimeraX build does not fetch third party libraries with rsync, it uses https and curl and does not need a password. So use the current ChimeraX source from github and you should not have that problem.</div><div class=""><br class=""></div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span><a href="https://github.com/RBVI/ChimeraX" class="">https://github.com/RBVI/ChimeraX</a></div><div class=""><br class=""></div><div class=""> Tom</div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""><blockquote type="cite" class=""><div class="">On Jul 3, 2021, at 5:51 AM, James Loy via ChimeraX-users <<a href="mailto:chimerax-users@cgl.ucsf.edu" class="">chimerax-users@cgl.ucsf.edu</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div dir="ltr" class="">Hello!<div class=""><br class=""></div><div class="">Thank you for creating such an amazing piece of software!</div><div class=""><br class=""></div><div class="">I'm trying to use portions of ChimeraX for part of a CIF file processing pipeline.
