abeona v0.37.2

A simple transcriptome assembler based on kallisto and Cortex graphs.

Installation
------------

The easiest way to install abeona is into a `conda <https://conda.io/miniconda.html>`_ environment.

After activating the conda environment, run:

.. code-block:: bash

conda install abeona -c conda-forge -c bioconda

Running
-------

The principal command is `abeona assemble`. This command assembles transcripts from cleaned
short-read RNA-seq reads in FASTA or FASTQ format. For more information, see:

.. code-block:: bash

abeona assemble --help

Toy Example
~~~~~~~~~~~

.. code-block:: bash

# Let's create a FASTA consisting of sub-reads from two transcripts: AAAAACCC and AAAAAGGG
$ for s in AAAAACC AAAAAGG AAAACCC AAAAGGG; do for i in $(seq 1 3); do echo -e ">_\n$s" >> input.fa; done; done

# Now feed the fasta to the graph assembly step with --fastx-single and to the kallisto filtering
# step with --kallisto-fastx-single.
$ abeona assemble -k 5 -m 4 --fastx-single input.fa --kallisto-fastx-single input.fa --kallisto-fragment-length 7 --kallisto-sd 1 -o test

v0.37.2
~~~~~~~

:Date: 2018-10-17

New features
............
