...It requires a phylogenetic tree of the common Newick data format as input, as well as three meta data files for samples, clade-defining nodes and clade color definitions - all in tab delimited format. Functionality within PhyloTrack shows the informative markers at each node in the phylogenetic tree, therefore highlighting clade-defining polymorphism. This functionality has been implemented using the tabix tool on the server side, providing simple and rapid access to the information at each tree node, including informative SNPs stored in VCF-similar files. These informative variants have been established by comparing allele frequencies between strain-types using ancestral node comparisons and FST measures of population differentiation.

...But if a series of SNP alleles differ from the ancestral pattern, then it may be more likely that an HRE has occurred, particularly if the allele pattern matches that from another part of the tree better than that of the ancestral node.

Perl Node Interface (PNI) is a node based visual programming environment. PNI makes easy to humans to write Perl programs. No Perl skill is required, programs are builded graphically. Perl coders can easily extend it writing new nodes.
