Project description

bio: making bioinformatics fun again

bio - command-line utilities to make bioinformatics explorations more enjoyable.

bio is a bioinformatics toy to play with.

Like LEGO pieces that match one another bio aims to provide you with commands that naturally fit together and let you express your intent with short, explicit and simple commands. It is a project in an exploratory phase, we'd welcome input and suggestions on what it should grow up into.

What does this software do?

If you've ever done bioinformatics, you know how even seemingly straightforward tasks require multiple steps, arcane incantations, and various other preparations that slow down progress.

Even well-defined, supposedly simple tasks can take a seemingly inordinate number of complicated steps. The bio package is meant to solve that tedium.

Usage examples

# Fetch genbank data
bio fetch NC_045512 MN996532 > genomes.gb

# Convert the first then bases of the genomes to FASTA.
bio fasta genomes.gb --end 10

# Align the coding sequences for the S protein
bio fasta genomes.gb --gene S --protein | bio align | head

# Print the GFF record that corresponds to the coding sequence for gene S
bio gff genomes.gb --gene S 

# Show the descendants of taxid 117565
bio taxon 117565 | head

# Show the lineage of a taxonomic rank.
bio taxon 117565 --lineage | head

# Get metadata on a viral sample
bio meta 11138 -H | head

# Define a sequence ontology terms
bio define exon

# Define a gene ontology terms
bio define food vacuole

Documentation

Detailed documentation is maintained at

Quick install

bio works on Linux and Mac computers and on Windows when using the Linux Subsystem.

pip install bio --upgrade

See more details in the documentation.

bio is stream oriented

bio supports stream oriented programming where the output of one task may be chained into the second. Take the example above but now start with a file acc.txt that contains just the accession numbers:

NC_045512
MN996532

we can run bio to generate a VCF file with the variants of the S nucleotides forming the S protein like so:

cat acc.txt | bio fetch | bio fasta --gene S | bio align --vcf | head

to print:

##fileformat=VCFv4.2
##FORMAT=<ID=GT,Number=1,Type=String,Description="Genotype">
##FILTER=<ID=PASS,Description="All filters passed">
##INFO=<ID=TYPE,Number=1,Type=String,Description="Type of the variant">
##contig=<ID=YP_009724390.1,length=3822,assembly=YP_009724390.1>
#CHROM  POS     ID      REF     ALT     QUAL    FILTER  INFO    FORMAT  QHR63300.2

YP_009724390.1  60      60C/T   C       T       .       PASS    TYPE=SNP        GT      1

Who is bio designed for?

The software was written to teach bioinformatics and is the companion software to the Biostar Handbook textbook. The targeted audience comprises:

  • Students learning about bioinformatics.
  • Bioinformatics educators who need a platform to demonstrate bioinformatics concepts.
  • Scientists working with large numbers of similar genomes (bacterial/viral strains).
  • Scientists who need to investigate and understand the precise details of a genomic region closely.

The ideas and motivations fueling bio have been developed while educating the many cohorts of students who used the handbook in the classroom. bio is an opinionated take on how bioinformatics, particularly data representation and access, should be simplified and streamlined.

Development

If you clone the repository, we recommend that you install it as a development package with:

python setup.py develop

Testing

bio can test itself, to run all tests execute:

bio test

Tests are automatically built from a shell script that mimics real-life usage scenarios.

Generating documentation

To generate the docs, you will need the bookdown package:

conda install r-bookdown r-servr

To run the docs in a browse:

make 

then visit http://localhost:8000
