The end-members input file contains information on the concentration ranges of tracers for the various end-members. In addition, this file determines which end-members are used in the analysis (together with the nendmembers keyword in the initialization file). Comment lines start with an !.

Blocks of end-member concentrations are specified by a bracketed end-member code on the first line: [end-member].

On the following lines, for each solute a tab-separated list must be entered containing: solute - distribution code - minimum value - maximum value - mean value - standard deviation. Order of the solutes is not important. G-EMMA only supports distributions 'U' (uniform) and 'G' (gaussian). The former uses the minimum - maximum values, while the latter uses the mean and standard deviation.

Only the first nendmembers end-members are used in the simulation.
