Filterconsensusreads before vs after mapping

[gevro]

Hi, Your best practices has two options: Filteringconsensusreads before, and Filteringconsensusreads after mapping the consensus reads.

https://github.com/fulcrumgenomics/fgbio/blob/main/docs/best-practice-consensus-pipeline.md

Are these functionally equivalent? Any reason for one vs the other?

Thanks.
