The ARB software is a graphically oriented package comprising various tools for sequence database handling and data analysis. A central database of processed (aligned) sequences and any type of additional data linked to the respective sequence entries is structured according to phylogeny or other user defined criteria.
Oligomap is a program for fast identification of nearly-perfect matches of small RNAs in sequence databases. It allows to exhaustively identify all the perfect and 1-error (where an error is defined to be a mismatch, insertion or deletion) matches of large sets of small RNAs to target sequences. Optimal performance is achieved at about 500000 query sequences
