+**What it does**
+
+ms2preproc is a software tool to preprocess MS/MS spectra, please see the citation below for more information.
+
+**Inputs and Parameters**
+
+ms2preproc is very specific about the formatting of the MGF file it parses. Therefore it is recommended that the MGF Formatter tool is used to create a MGF file specifically for ms2preproc prior to the use of this tool.
+
+The authors of this software recommend running ms2preproc with the following settings:
+
+  Mascot: 
+    Select top 200 peaks globally. 
+
+  Sequest: 
+    Select top 6 peaks in windows of size 30 m/z.
+
+  ProteinPilot: 
+    Select top 6 peaks in windows of size 30 m/z.
