This tool will Query a set of identifications against the METabolomics EXPlorer database.

It will take the input file and for each record it will query the 
molecular mass in the selected MetExp DB. If one or more compounds are found in the
MetExp DB then extra information regarding these compounds is added to the output file.

The output file is thus the input file enriched with information about 
related items found in the selected MetExp DB.  

**Notes**

The input file can be any tabular file, as long as it contains a column for the molecular mass
and one for the formula of the respective identification.
