"WebAlignment speed depends largely on the read length and alignment parameters used. Allowing many mismatches and using a short seed length (which is the default option for Bowtie 1, see below) tends to be fairly slow, whereas looking for near perfect matches can align around 5-25 million sequences per hour (using Bowtie 1).

WebThe theory behind aligning RNA sequence data is essentially the same as discussed earlier in the book, with one caveat: RNA sequences do not contain introns. Gene models in Eukaryotes contain introns which are often spliced out during transcription. RNA Sequences that span two exons will have a hard time mapping to the genome, which still ...
