Campus Description: ￼ Bioinformatik Praktikum
New sequencing technologies based on nanopores improve sequencing capabilities by allowing the sequence of large DNA molecules. Moreover, nanopores can also capture modifications in DNA, such as DNA methylation. This capabilities come with a higher sequencing error rate (1-2%) than previous next generation sequencing methods (0.1%). As usual, bioinformatics approaches are required to differentiate between technical noise and biological meaningful variants.
This practical seminar will focus on the use of Hidden Markov models for sequencing alignment and error correction for Oxford Nanopore sequencing reads. The lab task will be based on the implementation of bioinformatics pipeline including: integration of low-level analysis tools (i.e. short sequencing aligner) and development of a method for high level analysis (i.e. error correction and detection of Single-nucleotide polymorphism). We will use real data provided by the CAMDA 2017 challenges, which includes meta-genomes sequences in both Illumina and Nanopores technologies.
