## 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.
- 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.

Example:
`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
