Oyster_el_time

Matrix of amounts of pixels of each phase per sub-increment

phase_mat

Matrix containing colour and trace element data of the phases
 in the XRF phase map

phases

Function that takes the matrix of phase pixels per sub-increment
 together with the matrix of concentrations per phase to calculate the
 concentration of each trace element in every sub-increment.

Contains all the formulae of the growth and trace element uptake model described in the equally-named
Geoscientific Model Development paper (de Winter, 2017, <doi:10.5194/gmd-2017-137>). The model takes as input a file with X- and Y-coordinates of digitized
growth increments recognized on a longitudinal cross section through the bivalve shell, as well as a BMP file of an elemental map of the
cross section surface with chemically distinct phases separated by phase analysis. It proceeds by a step-by-step process described in
the paper, by which digitized growth increments are used to calculate changes in shell height, shell thickness, shell volume, shell mass
and shell growth rate through the bivalve's life time. Then, results of this growth modelling are combined with the trace element mapping
results to trace the incorporation of trace elements into the bivalve shell. Results of various modelling parameters can be exported in
the form of XLSX files.
