 ## Experimental haplotype calling pipeline
 
 There is now an experimental haplotype calling pipeline that uses freebayes for initial variant calling and flopp for read phasing with the called variants. It has a number internal QC steps for merging identical haplotypes. This pipeline requires further validation, but can theoretically produce multiple consensus sequences for each poliovirus population present within a sample. The pipeline has mostly be tested on VDPVs of two mixtures, but will be further assessed.
