The fasta programs offer several advantages over blast: Pairwise alignment is used to detect homologies between dierent protein or dna sequences, either as global or local alignments. How do their differences affect sensitivity of sequence search? Blast and fasta differ is the statistical evaluation of their output which would most likely affect their relative accuracy. • it is faster and more accurate to blast proteins (blastp) rather than nucleotides. Blast, the basic local alignment search tool, is perhaps the most widely used bioinformatics tool ever written. Probably every single one of you has done blast searches before, most likely using the ncbi web server and a precompiled.

Blast source is written c and c program needs to be compiled to get executable program but here we will download executables of blast. Blast and fasta differ is the statistical evaluation of their output which would most likely affect their relative accuracy. Fasta developed ~1985 by lipman and pearson (now many variants/updates/improvements) goal: Pairwise alignment is used to detect homologies between dierent protein or dna sequences, either as global or local alignments. Blast and fasta are two similarity searching programs that identify homologous dna sequences and proteins based on the excess sequence similarity. Both the software have been shown to perform equally well except for a few differences. Fasta and blast • both fasta, blast are based on heuristics • tradeoff: • it is faster and more accurate to blast proteins (blastp) rather than nucleotides. Lorenza bordoliswiss institute of bioinformatics. • both blast and fasta use this algorithm with varying heuristics applied in each case. Find alternative local alignments • use dynamic.
