Includes necessary columns for formulae:
C, H, O, N, S.
Provides columns corresponding to formulae lists which should contain the intensity values for each formula.
The name of the formulae list column will be treated as formulae list's id. To group formulae lists, assign them a common name and add a dash with any letter, i.e. for sample CHA, corresponding formulae lists are CHA-a, CHA-b, etc.
Input a general table: if a formula is present in one formulae list and not in another, put a zero for the latter.
