WebPaired-end tags (PET) (sometimes "Paired-End diTags", or simply "ditags") are the short sequences at the 5’ and 3' ends of a DNA fragment which are unique enough that they … WebPaired-end reads reduce the problem of multi-mapping, because a pair of reads must map within a certain distance of each other and in a certain order . Finally, long-read technologies, such as SMRT from Pacific Biosciences, provide reads that are long enough to sequence complete transcripts for most genes and are a promising alternative. http://sepsis-omics.github.io/tutorials/modules/pear/ dr metheral kingston
