Hi, thanks for reaching out. Can you give us a few more details:
- Are you using the web-based cross-matching tool, or the API (for instance in a notebook)?
- Have you imported your input file (as CSV?) to MyDB? Was the import successful? (can you confirm that the mydb table exists and can be queried?)
- If you are not using the web-based tool but the API, please post the exact query string that is failing for you.
Thank you,
Robert
