Create MSP Files from msPurity
------------------------------

* TO-DO: Averaging functionality
* TO-DO: Add citation for MSP
* TO-DO: Add PRECURSORTYPE if adducts available
* TO-DO: Create MSP from xcms/mzml files

Description
-----------

| This tool will extract the MSMS spectra data from an msPurity-frag4feature object into a file with MSP data format.
| Linking each precursor with its corresponding fragmentation spectra and associating the index within the msPurity object as the name UID.
| Currently, there are three different methods for extracting the data in case that more than one MSMS scan was acquired for the same precursor m/z. See Parameters.

Parameters
----------

**\1. msPurity frag4feature dataset** 

Result object from msPurity purityA-frag4feature functions.

**\2. Spectra use mode (if precursor was fragmented in >1 scans)**

* "Max Intensity" will only use the scan where the precursor m/z signal was maximal.

* "Weighted Average" will merge all the scans, group fragment m/z using a PPM deviation (see 3.) and weight the intensities based on the precursor intensity of that scan. 

* "All" will generate a single entry in the MSP file for each MSMS scan independently.  

**\3. PPM deviation for fragmentation spectra averaging**

Set the value only if you selected "Weighted Average" above, the PPM value is used to define the limits for m/z grouping into a single fragment. 
The weighting is based on the precursor intensity, meaning that the more intense the precursor signal was, the more intensity will its fragments contribute to the averaged spectra.
