Introduction
ecoflow/genomeqc is a bioinformatics pipeline that compares the quality of multiple genomes, along with their annotations.
The pipeline takes a list of genomes and annotations (from raw files or Refseq IDs), and runs commonly used tools to assess their quality.
There will be three different ways you can run this pipeline. 1. Genome only, 2. Annotation only, or 3. Genome and Annotation. Only Genome plus Annotation is functional
Genome and Annnotation:
- Downloads the genome and gene annotation files from NCBI
[NCBIGENOMEDOWNLOAD]
- Or you provide your own genomes/annotations - Describes genome assembly:
2a.
[BUSCO_BUSCO]
: Determines how complete is the genome compared to expected (protein mode). 2b.[QUAST]
: Determines the N50, how contiguous the genome is. 2c. More options - Describes your annotation :
[AGAT]
: Gene, feature, length, averages, counts. - Extract longest protein fasta sequences
[GFFREAD]
. - Finds orthologous genes
[ORTHOFINDER]
. - Summary with MulitQC.
Genome Only (in development):
- Downloads the genome files from NCBI
[NCBIGENOMEDOWNLOAD]
- Or you provide your own genomes - Describes genome assembly:
2a.

: Determines the N50, how contiguous the genome is. 2c. More options - Summary with MulitQC.
Annnotation Only (in development):
- Downloads the gene annotation files from NCBI

- Or you provide your own annotations. - Describes your annotation :

Usage
If you are new to Nextflow and nf-core, please refer to this page on how to set-up Nextflow. Make sure to test your setup with -profile test
before running the workflow on actual data.
First, prepare a samplesheet.csv
, where your input data points to genomes + or annotations:
Or to Refseq IDs of your species:
You can mix the two input types (in development).
Each row represents a species, with its associated genome, gff or Refseq ID (to autodownload the genome + gff).
You can run the pipeline using test profiles or example input samplesheets:
or
Please provide pipeline parameters via the CLI or Nextflow -params-file
option. Custom config files including those provided by the -c
Nextflow option can be used to provide any configuration except for parameters;
see docs.
