Examples

Shorten/Lengthen

import cstag

# Convert a cs tag from long to short
cs = "cs:Z:=ACGT*ag=CGT"

cstag.shorten(cs)
# => cs:Z::4*ag:3


# Convert a cs tag from short to long
cs = "cs:Z::4*ag:3"
cigar = "8M"
seq = "ACGTACGT"

cstag.lengthen(cs, cigar, seq)
# => cs:Z:=ACGT*ag=CGT

Call consensus

import cstag

cs_list = ["cs:Z:=ACGT", "cs:Z:=AC*gt=T", "cs:Z:=C*gt=T", "cs:Z:=C*gt=T", "cs:Z:=ACT+ccc=T"]
cigar_list = ["4M", "4M", "1S3M", "3M", "3M3I1M"]
pos_list = [1, 1, 1, 2, 1]

cstag.consensus(cs_list, cigar_list, pos_list)
# => cs:Z:=AC*gt*T

Output HTML report

import cstag

cs = "cs:Z:=AC+GGG=T-ACGT*at~gt10cg=GNNN"
output = "report"
description = "Example"

cstag.to_html(cs, output, description)
# => Output "report.html"
