bio_utils is a library of Python modules performing routine functions in bioinformatic scripts.


Many bioinformatic scripts perform similar or identical tasks internally during the execution of a program. Such tasks include reading FASTA files or filtering BLAST+ results. bio_utils contains numerous functions that quickly and simply handle simple, mundane, everyday tasks in a streamlined and simple fashion to save developers time. bio_utils aims to be as simple as possible, providing functionality without adding in unnecessary features, i.e. bio_utils is as vanilla as reasonable. This both increases the speed of most functions and greatly simplifies APIs.

Many libraries, such as SCREED and Biopython, already provide importable functions that execute these simple tasks. SCREED maintains a fairly simple API but is fairly slow and no one has updated the original repo since 2012-06-17. Numerous developers actively maintain Biopython and it is quite a bit faster, in some regards, than SCREED. However, Biopython stocks their functions with an enormous number of features that, while useful in a Python interpreter, are often ignored by programs or can be accomplished more quickly using built-in Python features, i.e. Biopython is bloatware to many developers. As aforementioned, bio_utils’ vanilla design overcomes both these libraries issues by providing both simplicity and speed.

At this point in time, bio_utils is quite small and its scope limited. The authors intend to slowly but surely increase this library’s repertoire over time. We welcome any and all contributions to our project.
