TagDust

Raw sequences produced by next generation sequencing (NGS) machines may contain adapter, linker, barcode and fingerprint sequences. TagDust2 is a program to extract and correctly label the sequences to be mapped in downstream pipelines.

TagDust allows users to specify the expected architecture of a read and converts it into a hidden Markov model. The latter can assign sequences to a particular barcode (or index) even in the presence of sequencing errors. Sequences not matching the architecture (primer dimers, contaminants etc.) are automatically discarded
