how treat FLAG 16 in ribosome footprint

Question

[dwc06631]

hello. first, sorry for that I'm not good at this field. I aligned reads to reference, and now I'm finding each read's start location from start codon to draw ribosome footprint figure. My question is

1. how to treat FLAG 16. I understand that they aligned to reverse strand, so they expressed in reverse complement forms in sam files. so if i have read1 that POS:25 and FLAG:16, is it correct to point read1 in 25 location from start codon in ribosome footpring? Just treat like other flag0 reads?

2. why we have reverse strand sequence in reads?
