Estimating the individualized HIV-1 genetic barrier to resistance using a nelfinavir fitness landscape.

abstract：BACKGROUND:To understand the evolutionary role of Lateral Gene Transfer (LGT), accurate methods are needed to identify transferred genes and infer their timing of acquisition. Phylogenetic methods are particularly promising for this purpose, but the reconciliation of a gene tree with a reference (species) tree is compu...
