Hi all, I just debugged a problem one of our users was having filtering BLAST tabular output using the "Filter" tool (version 1.1.0), where it was accepting 100% of the data.
He had entered the filter condition as: 'c8-c7>=0.8*c23' If you know how the tool works internally (essentially evaluating the string as a Python expression where c1 etc are variables), you can guess what happened. This evaluates as a non-empty string, which Python regards as True. Therefore every row in the file was accepted. What he should have used was 'c8-c7>=0.8*c23' without the quotes. I think this is an easy mistake to make, especially if copy & pasting an example from documentation. Can Galaxy do anything about this? Note that a simple hack to remove leading and closing quote characters would break some valid use cases, e.g. 'gi:' + c1 == c2 + '|D1', where there happens to be a quote character at the start and end.
