[galaxy-dev] Error with fastx reverse compliment

Hello, I'm getting an error with fastx tools on a local install of galaxy. From this error I can't tell if it's a problem with the file, database, or tool.

An error occurred with this dataset: zcat: /Volumes/Jose-Drobo/galaxy-dist/database/files/002/dataset_2875.dat.Z: No such file or directory fastx_reverse_complement: Premature End-Of-File (filename ='-')
