Write MoNA Spectra to MSP Format — write_msp

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.

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 (`"."`).

Value

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