A simple software program for sorting biological sequences into unique groups.

In this communication the author describes a software tool named "ChameleonSort". The software program, developed by the present author is useful in the sorting of biological sequence variants like those accumulating mutations while diverging from the common ancestors. Examples include viral protein variants, protein isomers, protein orthologs and polynucleotide sequences like DNA and RNA (1, 2). The program sorts the query sequences into unique groups. The output includes groups of sequences with unique permutation of the monomer units (amino acids and nucleotides) where the sequences of each group are identical but different from the sequences of every other group at least at one amino acid position or different in length by at least one monomeric unit. The algorithm has been implemented in the Visual Basic language which is a component of Microsoft’s Visual Studio (3). The entire code is made available as part of supplementary data in this communication. The user friendly program is available free of cost at Github.com (4), for downloading onto Windows-10 or higher operating systems.
