IRMa toolbox provides an interactive application to assist in the validation of Mascot® search results. IRMa reads MASCOT® result (using Matrix Science® Parser distributed free of charge) and automatically filters identified peptides. All relevant information is displayed in a structured manner, showing “proteins hits” details. User can then manually or automatically confirm or reject individual peptide spectrum matches.

Screenshots available here.

• Easy navigation within identification result
• Automatic or Manual filtering
• Dynamic grouping during validation
• Export validated results to Excel®
• Generate PDF document with annotated spectra and matched fragment ions table for publication purposes.
• Export validated results in a relational database
• Batch mode to automatically validate multiple identification results
• Automatic mode integrated to Mascot Daemon
• …

IRMa can be used in three different ways :

• Graphical : IRMa provides a graphical user interface allowing users to validate Mascot results manually or by applying filters and to navigate within the identification result.
• Batch : users can create scripts in order to repeat IRMa commands (parse, filter, save, export, etc) among many Mascot files.
• AutoIRMa : IRMa can also be run from command line. This feature allows you to integrate IRMa with Mascot daemon utility in order to create a fully automated pipeline.
• Scripts : Some hints on how to use scripts for Batch and AutoIRMa

Validated identification results can be exported within a relational database. These database must implements the Mass Spectrometry Identification database models.
