Hi, I’m wrapping a tool that needs it’s input to have a known file extension (an audio file, eg. .wav). Since Galaxy stores all data as .dat files the tool is falling over since it doesn’t know what .dat is. I thought I’d be able to get around this by hard linking the .dat file to the same name with a .wav extension (dataset_1.dat.wav), this works when I try it with the tool on the command line but within Galaxy it fails, here’s my <command>: ln $signal ${signal}.wav & /home/maus/maus OUTFORMAT=TextGrid LANGUAGE=$language BPF=$bpf INSKANTEXTGRID=$inskantextgrid INSORTTEXTGRID=$insorttextgrid MODUS=$modus MAUSSHIFT=$mausshift MINPAUSLEN=$minpauslen WEIGHT=$weight INSPROB=$insprob NOINITIALFINALSILENCE=$noinitialfinalsilence OUTSYMBOL=$outsymbol OUT=$output SIGNAL=${signal}.wav resulting in the job command line: ln /tmp/tmp7AZvx7/files/000/dataset_2.dat /tmp/tmp7AZvx7/files/000/dataset_2.dat.wav & /home/maus/maus OUTFORMAT=TextGrid LANGUAGE=aus BPF=/tmp/tmp7AZvx7/files/000/dataset_1.dat INSKANTEXTGRID=false INSORTTEXTGRID=false MODUS=standard MAUSSHIFT=10 MINPAUSLEN=5 WEIGHT=7.0 INSPROB=0.0 NOINITIALFINALSILENCE=no OUTSYMBOL=sampa OUT=/tmp/tmp7AZvx7/files/000/dataset_3.dat SIGNAL=/tmp/tmp7AZvx7/files/000/dataset_2.dat.wav I’m getting an error message from the tool: sox FAIL formats: can't open input file `/tmp/tmp7AZvx7/files/000/dataset_2.dat.wav': WAVE: RIFF header not found this suggests that the hard link didn’t get made. I tried copying the file instead but got the same result. I could go in and patch the tool script to be more forgiving but it would be good to find a solution that didn’t require that if possible.
