kb-python 0.24.0

Python wrapper around kallisto | bustools for scRNA-seq analysis

kb-python

kb-python is a python package that wraps the kallisto | bustools single-cell RNA-seq workflow [1]. It was developed by Kyung Hoi (Joseph) Min and Sina Booeshaghi.

The wrapper simplifies downloading and running of the kallisto [1] and bustools [2] programs. It was inspired by Sten Linnarsson’s loompy fromfq command (http://linnarssonlab.org/loompy/kallisto/index.html)

The kb program consists of two parts:

The kb ref command builds or downloads a species-specific index for pseudoalignment of reads. This command must be run prior to kb count, and it runs the kallisto index [1].

The kb count command runs the kallisto [1] and bustools [2] programs. It can be used for pre-processing of data from a variety of single-cell RNA-seq technologies, and for a number of different workflows (e.g. production of gene count matrices, RNA velocity analyses, etc.). The output can be saved in a variety of formats including mix and loom. Examples are provided below.
