sequana-pacbio-qc 1.0.1

QC on various type of pacbio data

This is is the pacbio_qc pipeline from the Sequana projet

Overview:

Quality control for pacbio datafiles (raw data or CCS files).

Input:

BAM files provided by Pacbio Sequencers.

Output:

HTML reports with various plots including taxonomic plot

Status:

production

Documentation:

This README file, the Wiki from the github repository (link above) and https://sequana.readthedocs.io

Installation

Just install this package:

pip install sequana_pacbio_qc

You will need samtools and kraken2 (optional) for the taxonomic analysis.

Usage

sequana_pacbio_qc --help
sequana_pacbio_qc --input-directory DATAPATH

If you want to filter out some BAM files, you may use the pattern in tab ‘input data’.

In the configuration tab, in the kraken section add as many databases as you wish. You may simply unset the first database to skip the taxonomy, which is experimental.

This creates a directory with the pipeline and configuration file. You will then need to execute the pipeline:

cd pacbio_qc
sh pacbio_qc.sh  # for a local run

This launch a snakemake pipeline. If you are familiar with snakemake, you can retrieve the pipeline itself and its configuration files and then execute the pipeline yourself with specific parameters:

snakemake -s pacbio_qc.rules -c config.yaml --cores 4 --stats stats.txt

Or use sequanix interface.

Requirements

This pipelines requires the following executable(s):

• sequana

• samtools

• kraken2

• multiqc

Details

This pipeline takes as inputs a set of BAM files from Pacbio sequencers. It computes a set of basic statistics related to the read lengths. It also shows some histograms related to the GC content, SNR of the diodes and the number of passes Finally, a quick taxonomy can be performed using Kraken. HTML reports are created for each sample as well as a multiqc summary page.

Kraken databases are not provided with the pipeline. This step is optional and not used by default.
