Otherwise you can convert the SAM to sorted BAM, use the BAM to BED converter in BEDTools, and convert BED to GFF in Galaxy…
It might be a little bit unusual to use the "generic feature format"
(GFF) to show where your reads map....but strictly speaking mapped reads
on a genome are 'features' as well.
You can do it the following way:
first use the "Convert SAM to interval" tool (NGS: SAM Tools), and use
the "BED-to-GFF converter" (Convert Formats)
or can simply convert in edit menu to BED, do not need to print full.
