refine, maximum valid expectation value

Syntax

This value is a positive floating point number represented as a character string.

Notes

1. No error is generated when an uninterpretable value is used.
2. If this parameter is missing, a default value of 0.01 is used.

Description

When the refinement process begins, the expectation values for all of the peptides found in the first pass search are calculated. Any protein that contains at least one peptide with an expectation value lower than the value for this parameter is then included in the list of proteins that will be used during the refinement process.
