outputAnnotationResult-peakPantheRAnnotation-method: Save to disk all annotation results as csv files

Description Usage Arguments Value Examples

Description

Save to disk all annotation results as annotationName_ ... .csv files: compound metadata (cpdMetadata, cpdID, cpdName) and spectra metadata (spectraMetadata, acquisitionTime, TIC), summary of fit (ratio of peaks found: ratio_peaks_found, ratio of peaks filled: ratio_peaks_filled, mean ppm_error: ppm_error, mean rt_dev_sec: rt_dev_sec), and a file for each column of peakTables (with samples as rows and compounds as columns)
