Multiple sequence alignment using partial order graphs
MOTIVATION Progressive Multiple Sequence Alignment (MSA) methods depend on reducing an MSA to a linear profile for each alignment step. However, this leads to loss of information needed for accurate alignment, and gap scoring artifacts. RESULTS We present a graph representation of an MSA that can itself be aligned directly by pairwise dynamic programming, eliminating the need to reduce the MS...
متن کاملMultiple flexible structure alignment using partial order graphs
MOTIVATION Existing comparisons of protein structures are not able to describe structural divergence and flexibility in the structures being compared because they focus on identifying a common invariant core and ignore parts of the structures outside this core. Understanding the structural divergence and flexibility is critical for studying the evolution of functions and specificities of protei...
متن کاملGenome-Wide Detection of Alternative Splicing in Expressed Sequences Using Partial Order Multiple Sequence Alignment Graphs
We present a method for high-throughput alternative splicing detection in expressed sequence data. This method effectively copes with many of the problems inherent in making inferences about splicing and alternative splicing on the basis of EST sequences, which in addition to being fragmentary and full of sequencing errors, may also be chimeric, misoriented, or contaminated with genomic sequenc...
متن کاملCombining partial order alignment and progressive multiple sequence alignment increases alignment speed and scalability to very large alignment problems
MOTIVATION Partial order alignment (POA) has been proposed as a new approach to multiple sequence alignment (MSA), which can be combined with existing methods such as progressive alignment. This is important for addressing problems both in the original version of POA (such as order sensitivity) and in standard progressive alignment programs (such as information loss in complex alignments, espec...
متن کاملMultiple Sequence Alignment Multiple Sequence Alignment
An algorithm for progressive multiple alignment of sequences with insertions " , 1. Introduction The problem of sequence alignment is to find the patterns of sequence conservation and similarity between pairs or sets of given sequences. In biological contexts, similarity between biological sequences usually amounts to either functional or structural similarities or divergence from a common ance...
