proalign - 0.603-4 main

ProAlign performs probabilistic sequence alignments using hidden Markov
models (HMM). It includes a graphical interface (GUI) allowing to (i)
perform alignments of nucleotide or amino-acid sequences, (ii) view the
quality of solutions, (iii) filter the unreliable alignment regions and
(iv) export alignments to other software.
.
ProAlign uses a progressive method, such that multiple alignment is
created stepwise by performing pairwise alignments in the nodes of a
guide tree. Sequences are described with vectors of character
probabilities, and each pairwise alignment reconstructs the ancestral
(parent) sequence by computing the probabilities of different
characters according to an evolutionary model.
