I have previously pasted lines from BED files into Galaxy. This does not seem to be working any more. Several days ago I could paste an simple entry like: chr3 71638312 71638369. The same entry does not work today. It tells me "failure preparing job" and "required metadata are missing". I've tried to add different columns to the line—strand, score etc. to no effect. How can I change my entry to be accepted by Galaxy? Thanks!
