Virus Classification by Pairwise Sequence Comparison (PASC)	2008-07-30		.txt	text/plain	3831	207	50	Pairwise sequence comparison (PASC) is a molecular classification tool for viruses. It calculates the pairwise identities of virus sequences within a virus family and displays their distributions, and can help determine demarcations at different taxonomic levels such as strain, species, genus, and subfamily levels. In the PASC system, pairwise global alignment is performed on complete genomes or particular protein sequences for each viral family, and their percentage of identity is calculated. For those virus families that are suitable for PASC analyses, demarcations can be easily determined and new viruses can be clearly placed into the correct taxonomy. PASC is a molecular classification tool for many virus families. It calculates the pairwise identities of virus sequences within a virus family and displays their distributions, and can help determine the demarcations at strains, species, genera, and subfamilies level.	./cache/cord-346904-aa88gtzr.txt	./txt/cord-346904-aa88gtzr.txt
