Preprocessing of raw SARS-CoV-2 reads

The raw reads available so far are generated from bronchoalveolar lavage fluid (BALF) and are metagenomic in nature: they contain human reads, reads from potential bacterial co-infections as well as true COVID-19 reads.

BROAD Best Practices Somatic CNV Panel is used for creating a panel of normals (PON) given a set of normal samples.

Common Use Cases

For CNV discovery, the PON is created by running the initial coverage collection tools individually on a set of normal samples and combining the resulting copy ratio data using a dedicated PON creation tool [1]. This produces a binary file that can be used as a PON. It is very important to use normal samples that are as technically similar as possible to the ...

Runs InterProScan on batches of sequences to retrieve functional annotations.

Transcripts annotation workflow

nf-kmer-similarity

This is a Nextflow workflow for running k-mer similarity

Usage

With a samples.csv file:

nextflow run czbiohub/nf-kmer-similarity --outdir s3://olgabot-maca/nf-kmer-similarity/ --samples samples.csv

With R1, R2 read pairs:

nextflow run czbiohub/nf-kmer-similarity --outdir s3://olgabot-maca/nf-kmer-similarity/ \ --read_pairs 's3://olgabot-maca/sra/homo_sapiens/smartseq2_quartzseq/{R1,R2}.fastq.gz,s3://olgabot-maca/sra/danio_rerio/smart-seq/whole_kidney_marrow_prjna393431/*{1,2}.fastq.gz' ...

Assembly, binning and annotation of metagenomes.

Introduction

This pipeline is for assembly, binning and annotation of metagenomes. It supports both short and long reads, quality trims the reads and adapters with https://github.com/OpenGene/fastp and https://github.com/rrwick/Porechop and performs basic QC with https://www.bioinformatics.babraham.ac.uk/projects/fastqc/.

The pipeline then:

assigns taxonomy to reads using https://ccb.jhu.edu/software/centrifuge/ and/or https://ccb.jhu.edu/software/kraken2/ ...

Methylation (Bisulfite-Sequencing) Best Practice analysis pipeline, part of the nf-core community..

The pipeline uses Nextflow, a bioinformatics workflow tool. It pre-processes raw data from FastQ inputs, aligns the reads and performs extensive quality-control on the results.

The pipeline is built using Nextflow, a workflow tool to run tasks across multiple compute infrastructures in a very portable manner. It comes with docker containers making installation trivial and results highly reproducible. ...
