Tools can error when the wrong dataset attributes (metadata) are assigned. Some of these wrong assignments may be:

• Tool outputs, which are automatically assigned without user action.

• Incorrect autodetection of datatypes, which need manual modification.

• Undetected attributes, which require user action (example: assigning database to newly uploaded data).

How to notice missing Dataset Metadata:

• Dataset will not be downloaded when using the disk icon {% icon galaxy-save %}.

• Tools error when using a previously successfully used specific dataset.

• Tools error with a message that ends with: OSError: [Errno 2] No such file or directory.

Solution:

Click on the dataset's pencil icon {% icon galaxy-pencil %} to reach the Edit Attributes forms and do one of the following as applies:

• Directly reset metadata

  • Find the tab for the metadata you want to change, make the change, and save.

• Autodetect metadata

  • Click on the Auto-detect button. The dataset will turn yellow in the history while the job is processing.
