Generic consensus construction from VCF calls
Version 1

Workflow Type: Galaxy

Generic consensus building

This workflow generates consensus sequences using a list of variants generated by Variant Calling Workflow.

The workflow accepts a single input:

  • A collection of VCF files

The workflow produces a single output:

  • Consensus sequence for each input VCF file

The workflow can be accessed at


ID Name Description Type
Depth-threshold for masking Depth-threshold for masking Sites in the viral genome covered by less than this number of reads are considered questionable and will be masked (with Ns) in the consensus sequence independent of whether a variant has been called at them or not.
  • int?
Reference genome Reference genome The reference genome
  • File
Variant calls Variant calls Collection of VCFs produced by upstream workflows for variation analysis
  • File[]
aligned reads data for depth calculation aligned reads data for depth calculation Fully processed BAMs as generated by upstream workflows for variation analysis. Note: for ARTIC data, these BAMs should NOT have undergone processing with ivar removereads.
  • File[]
min-AF for consensus variant min-AF for consensus variant Only variant calls with an allele-frequency greater this value will be considered consensus variants.
  • float?
min-AF for failed variants min-AF for failed variants Variant calls with an allele frequency higher than this value, but lower than the AF threshold for consensus variants will be considered questionable and the respective sites be masked (with Ns) in the consensus sequence.
  • float?
