PRIDE Converter converts mass spectrometry data from most common data formats (MASCOT .dat file for example) into PRIDE XML.
(PRIDE XML is the file format used for submission to the publicly available PRIDE database).
It presents a convenient, wizard-like graphical user interface, and includes efficient access to the Ontology Lookup Service (OLS).

Below are the main steps to follow. For more details, see PRIDE Converter help which is accessible from each panel of the wizard.

Tips:

• If you don't know which CV Term to use, you can always Browse Ontology
• To move up/down rows in tables (Protocol steps, etc.) right-click on a row and select Move Up or Move Down

1. Select Mascot DAT Files
