Get code
$ git clone git@github.com:UCL/cathpy.git
$ cd cathpyInstall code into virtual environment
$ python3 -m venv venv
$ source venv/bin/activate
$ pip install -e .If everything is installed and working properly then the following should work:

cathpy is a python package that contains bioinformatics tools and libraries
used in CATH (protein structure classification resource at UCL).
Hmmm.. that sounds like Yet Another Python Bioinformatics Toolkit?
Well it is... sort of.
Should I be using it?
If you are looking for a general Bioinformatics toolkit, you probably want to look at BioPython first.
This project does contain generic libraries and tools, however the code is new and the API may move around. It has been published mainly for internal use (within CATH), however it has been released as open source in case others find the tools helpful.
So, why doesn't this use BioPython?
We may well merge in some BioPython modules in the future. There are few features that BioPython does not currently handle (eg regarding fairly low-level manipulation of alignments). At some point, we may look into turning some of this code into suggestions / pull-requests.
This code base contains external tools that are not written and maintained by the authors of this project. If you use the results of these tools, please reference the relevant papers.
