castanyes blaves

Random ramblings about some random stuff, and things; but more stuff than things -- all in a mesmerizing and kaleidoscopic soapbox-like flow of words.

multiple alignment programs

Features of T-Coffee:

* Combines signals from heterogeneous sources, such as sequence-alignment programs, structure alignments, threading, manual alignment, motifs, and specific constraints

* Improved accuracy for a modest decrease in speed

* Combines local and global information

Features of Muscle:

* Optimize speed, accuracy, or a compromise between the two

* Quickly and accurately align tens or hundreds of sequences

* Align large numbers (thousands) of sequences, though not as quickly

* Refine existing alignments (whether obtained using Muscle or some other tool)

* Align two profiles

* Quickly cluster similar sequences

Features of ProbCons:

* Uses progressive alignment scheme with consistency-based alignment techniques

* Based on approximation to probabilistic model that can be iterated to account for multiple intermediate sequences when aligning two sequences
