Detailed Description

Representation of a nucleic acid sequence.

NASequence represents nucleic acid sequences (RNA) in OpenMS. Each NASequence consists of a vector of pointers to Ribonucleotides as well as RibonucleotideChainEnds representing the 5' and 3' ends of the sequence. Each Ribonucleotide has only a single instance. These are accessible through RibonucleotideDB. Modified Ribonucleotides are included in RibonucleotideDB and are expressed as the Modomics Short name surrounded by brackets when converted to string.
