Fasta2MS
Overview
This application digests and fragments fasta proteins into annotated MS spectra.
MS/MS spectra are returned in the standard output in mgf format.
Usage
usage: Fas2MS <fasta> [-a] [-d <arg>] [-f <arg>] [-h] [--no-digestion]
[-p <arg>] [-q <arg>] [-v]
-a,--annot-mode enable peak annot mode.
-d,--digest-motif <arg> define the motif for digestion:
<pre-cut> <cut-token> <post-cut>
<pre-cut> := (<AA> | <AA-class>)+
<post-cut> := (<AA> | <AA-class>)+
<AA> := [A-Z]
<AA-class> := '[' AA+ ']'
by default: Trypsin, [KR]|[^P].
-f,--frag-types <arg> define the fragment type(s):
a,b,c,x,y,z for backbone type fragments
i for immonium and p for precursor
by default: b,y.
-h,--help print this message.
--no-dig non digestion mode.
-p,--precision <arg> define the decimal precision for any
mass-to-charge ratio
by default: 6.
-q,--charge-numbers <arg> define the list of charge for fragments:
a sequence of integers like in 1,2,3:5,10:7
by default: 1.
-v,--version print the version info.
