BACKGROUND: The development of high-throughput sequencing technologies has
revolutionized the field of microbial ecology via the sequencing of phylogenetic
marker genes (e.g. 16S rRNA gene amplicon sequencing). Denoising, the removal of
sequencing errors, is an important step in preprocessing amplicon sequencing
data. The increasing popularity of the Illumina MiSeq platform for these
applications requires the development of appropriate denoising methods. RESULTS:
The newly proposed denoising algorithm IPED includes a machine learning method
which predicts potentially erroneous positions in sequencing reads based on a
combination of quality metrics. Subsequently, this information is used to group
those error-containing reads with correct reads, resulting in error-free
consensus reads. This is achieved by masking potentially erroneous positions
during this clustering step. Compared to the second best algorithm available,
IPED detects double the amount of errors. Reducing the error rate had a positive
effect on the clustering of reads in operational taxonomic units, with an almost
perfect correspondence between the number of clusters and the theoretical number
of species present in the mock communities. CONCLUSION: Our algorithm IPED is a
powerful denoising tool for correcting sequencing errors in Illumina MiSeq 16S
rRNA gene amplicon sequencing data. Apart from significantly reducing the error
rate of the sequencing reads, it has also a beneficial effect on their clustering
into operational taxonomic units. IPED is freely available at
