Confused about CloserScore #25

Closed Bank-tidy closed 7 months ago

Dear the author,

Thank you for developing such a useful program. I have been using GapFiller to fill gaps in my genome assembly at the scaffold level. However, I found that, although I achieved a decent score of 1.97, the alignment results of these reads using Minimap2 and BLAST are relatively poor. Do you have any recommendations for this issue? image

Best, Bank

By default, quarTeT GapFiller requires >1000 bp alignment with >40% identity at both frank 5000 bp to fill the gap. Score 1.97 means the identity of the two alignments are high. In your case, I assume that the alignment is a little far from the gap. If you feel unproper, you can increase -l or decrease -f to restrict the alignment more near the gap.

@Echoring Oh, I understand, thank you for your answer!
