Extension of the viral ecology in humans using viral profile hidden Markov models. [PDF]

PLoS ONE, 2018
When human samples are sequenced, many assembled contigs are "unknown", as conventional alignments find no similarity to known sequences. Hidden Markov models (HMM) exploit the positions of specific nucleotides in protein-encoding codons in various ...

Diversity, recombination and misclassification in the family Geminiviridae: Insight from bioinformatics analysis.

PLoS ONE
The family Geminiviridae comprises 15 genera and over 500 species of diverse plant-infecting viruses. Previous studies on this virus's diversity primarily focused on the members' selection without considering the entire genomic divergence.
