I am using augur align for multiple sequence alignment,
and I am not sure about the insertions csv output file format.
each column that represents an insertion has a title as follows: Xbp @ ref pos Y
insertion: 2706bp @ ref pos 1968.
what does the Xbp stand for?
In some cases it matches the nucleotide fragment length that was inserted in that sample, but in other cases it does not.
Thank you in advance,
