How do I convert my raw data to text to use with ProMass for the Web?

There are a few ways to do this depending on the platform you’re using. On Xcalibur, using Qual Browser, you open your raw file, produce the spectrum of interest, pin and right-click the mass spectrum and choose “Export Clipboard (Exact Mass)”. Do not export nominal mass data, as the m/z data will be truncated to the nearest integer value. The spectrum is now on your clipboard and can be pasted as text. On other platforms you simply need to produce a text spectrum of m/z, intensity pairs. The spectrum may be space, tab, or comma-delimited.
