Formula conversion

Computes empirical formula required to add to the desired type

Computes the empirical formula required to be added to convert an internal residue (inside an AA sequence) to that of a residue of the desired type. For example, to obtain the conversion formula for an internal ion to a "y ion", use getInternalToYTerm().

Formulae that need to be added to the internal residues to get to fragment type from http://www.matrixscience.com/help/fragmentation_help.html

Detailed Description

Representation of a residue.

This class represents residues. Residues can have many different attributes, like the formula physico-chemical values of properties and so on.

A very important property of residues are their modifications. By default no modification is present. Any modification which is present in the ModificationsDB can be applied, if appropriate.
