bool | isValidProduct_ (const String &sequence, int pos, int length, bool ignore_missed_cleavages, bool allow_nterm_protein_cleavage, bool allow_random_asp_pro_cleavage) const |
supports functionality for ProteaseDigestion as well (which is deeply weaved into the function) To avoid code duplication, this is stored here and called by wrappers. Do not duplicate the code, just for the sake of semantics (unless we can come up with a clean separation) Note: the overhead of allow_nterm_protein_cleavage and allow_random_asp_pro_cleavage is marginal; the main runtime is spend during tokenize_() More... | |
std::vector< int > | tokenize_ (const String &sequence, int start=0, int end=-1) const |
Digests the sequence using the enzyme's regular expression. More... | |

Class for the enzymatic digestion of RNAs.
void digest | ( | const String & | rna, |
std::vector< String > & | output, | ||
Size | min_length, | ||
Size | max_length | ||
) | const |
Performs the enzymatic digestion of an RNA.
Only fragments of appropriate length (between min_length
and max_length
) are returned.
There are two complications: 1. The original RNA may have terminal phosphates ("p"), which we want to ignore, but not remove. 2. The enzyme may add modifications (e.g. "p") on the 5' or 3' ends of cleavage products, but NOT on the original 5' or 3' ends of the RNA.
void setEnzyme |
Sets the enzyme for the digestion.
void setEnzyme | ( | const String & | name | ) |
Sets the enzyme for the digestion (by name)
