Can I produce one consensus sequence for each strand of a molecule?

Yes, please use --by-strand. Make sure that you have sufficient coverage, as --min-passes are per strand in this case. For each strand, ccs generates one consensus read that has to pass all filters. Read name suffix indicates strand. Example:

m64011_190714_120746/14/ccs/rev
m64011_190714_120746/35/ccs/fwd

How does --by-strand work? For each ZMW:

• Determine orientation of reads with respect to the one closest to the median length
• Sort reads into two buckets, forward and reverse strands
• Treat each strand as an individual entity as we do with ZMWs
  • Apply all filters per strand individually
  • Create a draft for each strand
  • Polish each strand
  • Write out each polished strand consensus
