Comet parameter: scan_range

  • Defines the scan range to search. Only spectra within (and inclusive) of the specified scan range are searched.
  • This parameter works only with mzXML and mzML inputs files.
  • Two digits are specified for this parameter. The first digit is the start scan and the second digit is the end scan.
  • As of now, it looks like the first digit must be an MS/MS scan.
  • When the start scan is set to 0, this parameter setting is ignored irrespective of what the end scan is set to.
  • When the end scan is less than the start scan, this parameter setting is ignored.
  • The default value is "0 0" if this parameter is missing.

scan_range = 0 0     search all scans
scan_range = 0 1000     search all scans (because first entry is 0)
scan_range = 1000 1500     search only scans 1000 to 1500
