Comparative homology agreement search: an effective combination of homology-search methods.

Many methods have been developed to search for homologous members of a protein family in databases, and the reliability of results and conclusions may be compromised if only one method is used, neglecting the others. Here we introduce a general scheme for combining such methods. Based on this scheme, we implemented a tool called comparative homology agreement search (chase) that integrates diff...

Homology Search Methods

Homology search methods have advanced substantially in recent years. Beginning with the elegant Needleman-Wunsch and Smith-Waterman dynamic programming techiques of the 1970s, algorithms have been developed that were appropriate for the data sets and computer systems of their times. As data sets grew, faster but less sensitive heuristic algorithms, such as FASTA and BLAST, became a dominant for...

Modern Homology Search

Dynamic programming [1] has full sensitivity, but too slow for large scale homology search. FASTA / BLAST type of heuristics [2] trade sensitivity for speed. Can we have both sensitivity and speed? We present the mathematical theory of optimized spaced seeds which allows modern homology search to achieve high sensitivity and high speed simultaneously. The spaced seed methodology is implemented ...

Homology search for genes

MOTIVATION Life science researchers often require an exhaustive list of protein coding genes similar to a given query gene. To find such genes, homology search tools, such as BLAST or PatternHunter, return a set of high-scoring pairs (HSPs). These HSPs then need to be correlated with existing sequence annotations, or assembled manually into putative gene structures. This process is error-prone ...

Quick, Practical Selection of Effective Seeds for Homology Search

It has been observed that in homology search gapped seeds have better sensitivity than ungapped ones for the same cost (weight). In this paper, we propose a probability leakage model (a dissipative Markov system) to elucidate the mechanism that confers power to spaced seeds. Based on this model, we identify desirable features of gapped search seeds and formulate an extremely efficient procedure...
