2nd Window GeneOrder
Compare the numerical order of protein-coding genes in two genomes, using GenBank genome files. Or compare a user-created list of protein sequences with a genome or another list. Program creates a dotplot of matches in proteins coded by genes, plotted in numerical order along the genome (or list). Points are plotted at different levels of significance for matching amino acid sequences. Program also generates a clickable list of matches. Genome size limited to less than 250 kb.
