Figure 4From: In silico segmentations of lentivirus envelope sequencesRegions predicted by the combined hidden Markov model trained on EIAV, HIV, SIV, and SRLV SU. The graphs display the regions predicted by the first order combined HMM, on sequences of EIAV, HIV, SIV, SRLV, BIV and FIV SU. The schematic organization of SU with the position of the variable regions (hatched boxes) and of the constant regions (—), as defined by classical amino-acid alignments, is represented under the graphics.Back to article page
