Central facility for high-throughput sequencing and bioinformatics

Accessible sequencing platforms

Next Generation Sequencing (NGS) methods allow high throughput decoding of DNA or RNA sequences. Typical applications are genome sequencing, transcriptome and metagenome analyses or the sequencing of selected genomic loci (amplicon sequencing). Such data can be used for sequencing unknown DNA, screening for sequence variations and polymorphisms, quantification of RNA transcripts or the characterisation of non-coding RNAs. The mapping of protein binding positions on genomic DNA is also possible (ChIP-Seq).

The project Z1 is the central hub for generation and analysis of NGS data for the CRC900, using different sequencing platforms (run by CRC members or at collaborating institutions) and providing a spectrum of bioinformatics tools for the subsequent data analysis of the data. CRC members are advised in the design and execution of experiments involving next generation sequencing. The Z1 team will help in selecting the most scientifically adequate and cost-effective sequencing approach and will assist in the primary data evaluation and in the selection of appropriate tools for further analysis and display of the results.

Scientific approach

The Z1 project participated so far in the generation of NGS data by different platforms mainly for de novo or re-sequencing approaches of bacteria and viruses and for RNA-Sequencing of viruses and mice. Furthermore, microbiome and metagenome sequencing was done from sputum samples of infected patients.
A multitude of software tools can be utilized for NGS data evaluation by the Z1 project or, with its assistance, by users from the CRC900. For various tasks one or more methods and programs (mainly open source software) were tested to enable the supply of appropriate tools for data analysis and presentation for the different feasible intentions of NGS projects.

For certain applications the Z1 project has put up standardised evaluation pipelines:

  • Quality check and trimming of the raw data generated by the sequencing platforms

  • Primary alignment of the reads to reference sequences and de novo assembly

  • Quantitative analysis of metagenome datasets, unravelling the composition of microbial communities (bacteria, viruses, fungi)

For a number of other tasks suitable software tools are available for data evaluation and/or could be recommended to the users, e. g.:

  • Calling genomic variations (SNPs, indels, large deletions) for bacteria, viruses and eukaryotes

  • Genome comparisons and screening for genome rearrangements

  • Automated sequence annotation and creation of genome atlases

  • Transcriptome analysis from RNA-Seq. data, quantification of transcripts and determination of their starting positions

  • Identification of methylation positions from SMRT sequencing data

  • Microbiome analyses

  • Tests of molecular evolution modes, phylogeny of genes

  • Genome composition, genome linguistics

  • Composition of heterogeneous populations, identification of quasi-species

Genome comparison and display of variations

Methylome analysis based on SMRT sequencing

Quantitative microbiome analysis
