Hi Felix

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)

I hope this helps, Hans

Hi, is there an easy way to use Galaxy to convert SAM to GFF? thx, Felix

How so?

SAM/BAM shows you where your reads map, GFF is used for annotation (e.g. where the genes are and what they may do).

Are you talking about using SAM/BAM transcriptome mapping (RNA-Seq) for gene finding?
