...NNmapper can map a query read (1) to the library read that gives the smallest distance (most similar), (2) to the library read that gives the smallest distance while the distance is smaller than a threshold, or (3) all library reads that have distances smaller than threshold.
NNmapper has high error-tolerant and is suitable for any read lengths. NN reports all mapping locations for multi-reads.
MATLAB installation required. Mac or Linux system required.
