MaltExtract - extracting ancient reads and understanding what maps at Genus level

MALT: Megan Alignment Tool
1

Hi,
Actually I have two questions related to MaltExtract output:

  1. Once I’ve run MaltExtract to identify ancient reads, is there a way to output the reads that map to specific taxa in fasta format for further analysis? Alternatively, can you form a rma file with just ancient reads?

  2. When MaltExtract is asked to identify reads at a target genus, does it summarise the reads that map best to that taxon as well as all the sub-taxa below it, or does it only look at the reads that map best at that level and can’t be placed any lower?

Thanks,
Hannah
