 Presuming your data, bias, and flats are all binned the same way and your file list is good, this should crunch away for way longer than seems necessary for such basic data processing, but eventually return a bunch of files prepended with ''​rg''​. ​ (It will also write out intermediate files prepended with just ''​g'',​ which you should promptly delete so you don't get them confused. ​ Note the confusing terminology given that two of GMOS's broadband filters are ''​r''​ and ''​g'',​ which of course this prefix has nothing to do with.  Sigh.) Presuming your data, bias, and flats are all binned the same way and your file list is good, this should crunch away for way longer than seems necessary for such basic data processing, but eventually return a bunch of files prepended with ''​rg''​. ​ (It will also write out intermediate files prepended with just ''​g'',​ which you should promptly delete so you don't get them confused. ​ Note the confusing terminology given that two of GMOS's broadband filters are ''​r''​ and ''​g'',​ which of course this prefix has nothing to do with.  Sigh.)
