Precursor search in local spectral MS/MS library¶
Description¶
Feature list methods → Annotation → Search precursor mass → Precursor search in spectral libraries
This module uses a local spectral MS/MS library to search for putative precursor ions in a feature list.
Supported formats:
- MoNA *.json,
- NIST *.msp,
- GNPS *.json (internal library submission format),
- and JCAMP-DX *.jdx.
Parameters¶
Spectral libraries file (MS/MS)¶
Name of the library file of the supported format.
Precursor m/z tolerance¶
Matches the average row m/z against the precursor m/z of the spectral library entry
Retention time tolerance¶
Optional parameter, should only be used if the DB entry has a retention time
