Generic genomic data plotting tool. Output from our generic genomic data plotter used to plot B-allele frequency from Illumina 1M SNParray data. Plot with two tracks; tumour (red) and normal (black). Output can be (top) a whole genome overview (shown here in part), or (middle) a single chromosome, or (bottom) a subregion of a chromosome defined by the user (here chr16, 60MB-end). Many parameters such as the colour and sizes of the data points may be adjusted by the user as required.
