pFind Studio: a computational solution for mass spectrometry-based proteomics


pXtract v2.0 is a portable application to extract text-plain spectra from binary Thermo Scientific RAW files. The supporting output formats are MS1, MS2, MGF. Xcalibur must be installed first due to the invocation of Thermo’s Xcalibur APIs in this program. You can use it without installation. After downloading the software, you need to unzip the file. There are two executable files, pXtract.exe and xtract.exe. pXtract.exe provides an user interface, while xtract.exe actually do the job of data extraction. You can either choose to use the user interface or directly use the kernel program (xtract.exe). To use the kernel program well, the user guide can give you some instructions.

System Requirements:

* Microsoft Windows operating system

* Thermo Scientific Xcalibur 2.0.5 supports well for data produced by LTQ-Orbitrap or LTQ-FTMS. For Q Exactive data you need Xcalibur 2.2 or a later version.

Details can be found in the user guide.
