Rthur converts mass spectrometry data in Thermo .RAW files to mzXML, an open data format supported by many proteomics applications and software pipelines.

In contrast to other existing mzXML conversion utilities, Rthur uses Thermo Foundation 3.0 libraries and supports data produced by newer models of Thermo mass spectrometer. The program is specifically designed for use with Orbitrap Fusion data, and is also tested to be fully compatible with the LTQ Orbitrap and Q Exactive Plus.
