BLAST program is widely used tool to find protein and DNA databases for sequence similarities. For protein comparisons, various definitions, algorithmic and statistical improvements described here allows the BLAST program execution time will decrease substantially while increasing their sensitivity to weak similarity. New criteria to trigger the expansion of word hits, combined with new heuristics […]Continue Reading
Fast, scalable generation of high-quality protein multiple sequence alignments using Clustal Omega.
Multiple sequence alignments are fundamental to many methods of sequence analysis. Most alignments computed using a heuristic progressive alignment. This method began to be a bottleneck in some pipeline analysis when dealing with thousands of sequence data set size. Some methods allow the calculation of a larger set of data while sacrificing quality, and others […]Continue Reading
