چکیده

The lion’s share of bacteria in various environments cannot be cloned in the laboratory and thus cannot be sequenced using existing technologies. A major goal of single-cell genomics is to complement gene-centric metagenomic data with whole-genome assemblies of uncultivated organisms. Assembly of single-cell data is challenging because of highly non-uniform read coverage as well as elevated levels of sequencing errors and chimeric reads. We describe SPAdes, a new assembler for both single-cell and standard (multicell) assembly, and demonstrate that it improves on the recently released E +V SC assembler (specialized for single-cell data) and on popular assemblers Velvet and SoapDeNovo (for multicell data). SPAdes generates single-cell assemblies, providing information about genomes of uncultivatable bacteria that vastly exceeds what may be obtained via traditional metagenomics studies. SPAdes is available online (http://bioinf.spbau.ru/spades). It is distributed as open source software.

hybridSPAdes: an algorithm for hybrid assembly of short and long reads

MOTIVATION Recent advances in single molecule real-time (SMRT) and nanopore sequencing technologies have enabled high-quality assemblies from long and inaccurate reads. However, these approaches require high coverage by long reads and remain expensive. On the other hand, the inexpensive short reads technologies produce accurate but fragmented assemblies. Thus, a hybrid approach that assembles l...

Assembling short reads from jumping libraries with large insert sizes

MOTIVATION Advances in Next-Generation Sequencing technologies and sample preparation recently enabled generation of high-quality jumping libraries that have a potential to significantly improve short read assemblies. However, assembly algorithms have to catch up with experimental innovations to benefit from them and to produce high-quality assemblies. RESULTS We present a new algorithm that ...

I-37: Establishing High Resolution Genomic Profiles of Single Cells Using Microarray and Next-Generation Sequencing Technologies

The nature and pace of genome mutation is largely unknown. Standard methods to investigate DNA-mutation rely on arraying or sequencing DNA from a population of cells, hence the genetic composition of individual cells is lost and de novo mutation in cell(s) is concealed within the bulk signal. We developed methods based on (SNP-) arraying and next-generation sequencing of single-cell whole-genom...
