plotPNG: Routine to generate PNG plots using the Diversity Assay Analysis Tool

Description

plotPNG uses various passed input, output and analysis parameters for performing an analysis on the data from an HIV Diversity Assay. The data consists of fluorescence measures, the analysis identifies candidate melting temperatures, peak changes in fluorescence and other statistics as they relate to the data. A PNG showing the fluorescence and dFluorescence curves together with the identified points for T1, T2 and Tm is generated for each sample. Parameters are listed below (default values are in parenthesis).
