SARS-CoV analysis. These sequence tracks show a BLASTX analysis of the SARS-CoV virus against (1) avian bronchitis virus, (2) bovine coronavirus, (3) human coronavirus 229E, (4) murine hepatitis, (5) porcine epidemic diarrhea virus, and (6) transmissible gastroenteritis virus. The last sequence track is SARS-CoV annotation imported from NCBI. This image shows dissimilarities between the SARS-CoV virus and other related viruses. These dissimilarities are pronounced in the structural proteins at the 3′ end (right). The score for each BLASTX hit is represented by height for each corresponding 3D feature in Sockeye. (Inset) The top view clearly shows the nature of the alignment.
