SNiPlay

Web-based tool, polymorphism discovery and analysis. 1. A pipeline combining tools to detect SNPs and to compute statistical indices and graphical layouts for SNP data. It sends sequences and genotyping data into a series of modules; physical mapping to a reference genome, annotation, SNP frequency determination in user-defined groups, haplotype reconstruction and network, linkage disequilibrium evaluation, and diversity analysis (Pi, Watterson's Theta, Tajima's D). 2. A database storing polymorphisms, genotyping data and grapevine sequences released by public and private projects.
