A cross-platform viewer utilizing the QT SDK and pyqtgraph to visualize mass spectrometry peaklist files. Also supported are opening of results from search engines from X!Tandem, Mascot, and Proteome Discoverer. The impetus for this project was a way to view mass spec data on linux since a majority of viewers were lacking.

Build Status

A cross-platform viewer to open up mass spec peaklist files.

To use, simply drag and drop a file onto the program. Multiple tabs are provided to allow for any number of files to be open concurrently. Dragging multiple files into a window will open all them at once for a combined view. Holding Control+dropping a file will append it to the current view (this way, you can even mix & match file types).

The current goal is functionality -- elegance can come later.

Installation: You need the following installed: PyQt4 -- install instructions are here: http://pyqt.sourceforge.net/Docs/PyQt4/ pyqtgraph

The rest can be done with: pip install -r requirements.txt

Supported: mgf files - on first load the mgf file will be indexed for random access. This is a one time cost, but it is worth it.

X!Tandem xml files

Proteome Discovered .msf files - These load very fast, anyone used to PD's abysmal (and unthreaded) speed will appreciate this

MZML/PepXML

Mascot DAT Files
