To generate a new AMT database in the MS Access format (.mdf file) from a given User context, follow these steps:

• Select the User context you want to export
• Select MS Identifications > Context > Export > Create AMT database from the main menu bar.
• Browse to a folder where you want to save the AMT database file and click Open.
• A confirmation dialog will indicate when saving process is finished.
  

Note : Before generating a new AMT db from a context, protein grouping should have been executed !

Below is the AMT database model showing relationships between tables in MS Access.
Only the three tables AMT, AMT_Proteins and AMT_to_Protein_Map are populated. The other tables doesn't contain any records. They will be later populated in the AMT pipeline.

• The AMT table contains all the peptides of the context.
• The AMT Proteins table contains all the proteins of the context.
• The AMT to Protein Map table links the two previous tables to indicate by which peptides proteins are identified.
