SEQUEST TQ

Sequest TQ iteratively searches through a protein database to determine the amino acid peptide sequence that either:
1) matches a given tag & tag masses,
2) matches an auto-generated tag & tag masses and matches an input MSMS spectrum by means of correlation analysis, O R
3) matches a given tag & tag masses and matches an input MSMS spectrum by means of correlation analysis.
Output is saved as a .out file to the /wfs/dbase/output_files directory and takes the name of file entered on the .d ta/output file line.
