Workflows

Post-genome assembly quality control workflow using Quast, BUSCO, Meryl, Merqury and Fasta Statistics, with updates November 2024.

Workflow inputs: reads as fastqsanger.gz (not fastq.gz), and primary assembly.fasta. (To change reads format: click on the pencil icon next to the file in the Galaxy history, then "Datatypes", then set "New type" as fastqsanger.gz). Note: the reads should be those that were used for the assembly (i.e., the filtered/cleaned reads), not the raw reads.

What it does: ...

Assess genome quality; can run alone or as part of a combined workflow for large genome assembly.

• What it does: Assesses the quality of the genome assembly: generate some statistics and determine if expected genes are present; align contigs to a reference genome.
• Inputs: polished assembly; reference_genome.fasta (e.g. of a closely-related species, if available).
• Outputs: Busco table of genes found; Quast HTML report, and link to Icarus contigs browser, showing contigs aligned to a reference ...

Assembly with Flye; can run alone or as part of a combined workflow for large genome assembly.

• What it does: Assembles long reads with the tool Flye
• Inputs: long reads (may be raw, or filtered, and/or corrected); fastq.gz format
• Outputs: Flye assembly fasta; Fasta stats on assembly.fasta; Assembly graph image from Bandage; Bar chart of contig sizes; Quast reports of genome assembly
• Tools used: Flye, Fasta statistics, Bandage, Bar chart, Quast
• Input parameters: None required, but recommend ...
