kSNP
kSNP4 does SNP discovery and SNP annotation from whole genomes
...kSNP4 can analyze both complete (finished) genomes and unfinished genomes in assembled contigs or raw, unassembled reads. Finished and unfinished genomes can be analyzed together, and kSNP can automatically download Genbank files of the finished genomes and incorporate the information in those files into the SNP annotation.
No programming skills are required to use kSNP4
