write_msp_mona: Write MoNA Spectra to MSP Format

In tidymass/metid: Metabolite identification based on MS1 and MS2 spectra

Write MoNA Spectra to MSP Format

Description

This function writes positive and negative mode MS2 spectra from a given 'databaseClass' object to MSP format files. The spectra are written separately for positive and negative ionization modes.

Usage

write_msp_mona(database, path = ".")

Arguments

database	An object of class 'databaseClass' containing spectral data and metadata.
path	A character string specifying the directory where the MSP files will be written. Defaults to the current directory ('"."').

Details

This function extracts the spectra from a 'databaseClass' object and writes them into MSP files. The positive mode spectra are written to 'spectra_pos.msp' and the negative mode spectra are written to 'spectra_neg.msp'. Each entry in the MSP file includes information such as the compound name, precursor type, ion mode, collision energy, and the corresponding MS2 spectrum.

Value

This function does not return any value. It writes MSP files for positive and negative mode spectra in the specified directory.
