We just released an update to CPAS, version 1.4-4355, available immediately via the download page. This release includes a few improvements from the version we distributed for ASMS via CD and our download site. Changes include:

• Fix Mascot2XML pepXML converter on Windows (Issue #1440)
• Allow sorting and filtering on protein annotation columns in protein views (Issue #1439)
• Allow exporting ProteinProphet information to Excel (Issue #1435)
• Improve PeptideProphet discriminant function for native X! Tandem scoring.

If you're running CPAS 1.3 or earlier, now is a great time to upgrade to CPAS 1.4. For a list of new features in 1.4, see What's New in CPAS 1.4.

If you already installed CPAS 1.4 via a CD you received at ASMS or from a download prior to 7/8/06 you should upgrade if you are encourtering any of the above issues or want the latest version of X! Tandem PeptideProphet support.

The Windows installer is the easiest way to install or upgrade an existing CPAS installation. It will upgrade any existing CPAS 1.3 or 1.4 system that was originally installed using the Windows installer.
