How to deal with it?,help!!!
Is there a problem with my diamond input?

You should update to the latest release of Megan
The release that you are using doesn’t support the mapping db file.
You are using the metadata file option to supply the mapping database, which is an error
Please use das-meganizer rather than daa2rma

Thank you for your advice, [Daniel] Leader
