How to build a minimum spanning trees from the local WGS NextGene processing results? Need to find a proper way to visualize postprocessing results of WGS NextGene software data. I have aligned a set of 144 MDR tuberculosis against a Beijing reference and want to report data correctly with charts, tables and plots, etc. to perform a microevolution analysis. Please, advise tools and approaches. NextGene lacks several visualization capabilities, though it is a perfect aligner and VCF productor.
