There is probably a format or metadata issue with the input. A few items to check:
- The datatype of the dataset (input file) is set and matches the instructions on the tool form for the expected type (some form of tabular data)
- The columns in the dataset are set correctly to match the dataset contents
- The dataset itself was uploaded into Galaxy correctly - all lines, all columns, no extra spaces between columns, only one tab between columns
Click on the "pencil" icon for a dataset (upper right corner) to reach the Edit Attribute forms where the first two can be reviewed/edited as needed. Tools in the group Text Manipulation can be used to investigate actual content if viewing with the "eye" icon does not reveal a problem.

If you are unable to resolve the issue, can it be reproduced at http://usegalaxy.org (if not working there already)? If yes, please send a shared history link to firstname.lastname@example.org. Please also include a link to this post so we can associate the two.
Thanks, Jen, Galaxy team
