-
Peptide Length: lower and upper limits for the peptide length.
-
Precursor m/z Deviation: The higher precursor mass error allowed in order to filter out outliers.
-
Missed cleavages: lower and upper limits for the number of missed cleavages.
-
Isotopes: lower and upper limits for the isotopes.

Exclude Unknown PTMs: When using SearchGUI with a modification at a particular amino acid
on a peptide terminus, X!Tandem will search this modification on every termini and amino acid. If you post-process your results with PeptideShaker using the
option Exclude Unknown PTMs, the PSMs presenting inconsistent modifications will be discarded. You can thus artificially obtain the desired
results although the modification is a priori not compatible with X!Tandem.
Leaving a field blank results in disabling the filter.
