Hi, Compara functionality is now added to the pgp viewer. What this means is you can now compare certain assemblies against each other. In most cases, pgp or agp viewers are compared to wgs assemblies. Visually the analysis will display all the assemblies being compared against each other and return their syntenic regions in the browser. For a 2-3 min quick example on what you can use Compara for, check out this entry from the blog: http://pgpviewer.blogspot.com/2011/08/pgp-compara-multiple-assembly-analysi… Please note for the most recent pgpviewers released yesterday, the compara analysis are not available, but will be shortly. The current assemblies with compara are listed in the blog. Any other issues, questions or comments please email pgp-help(a)sanger.ac.uk Will _______________________________________________ pgpviewer-announce mailing list pgpviewer-announce(a)sanger.ac.uk http://lists.sanger.ac.uk/mailman/listinfo/pgpviewer-announce
