Evaluation of wastewater surveillance results for SARS-CoV-2 at the national scale in the Slovak Republic.

As the COVID-19 transits to endemicity, the frequency of clinical testing and its utility for determining lineage prevalence has declined. This situation is not unique to Slovakia but reflects a global trend, as attention shifts from COVID-19 to other post-pandemic issues and emerging global health challenges. Nevertheless, the pandemic itself has spurred advancements in monitoring the epidemiological situation.

SnakeLines: integrated set of computational pipelines for sequencing reads.

With the rapid growth of massively parallel sequencing technologies, still more laboratories are utilising sequenced DNA fragments for genomic analyses. Interpretation of sequencing data is, however, strongly dependent on bioinformatics processing, which is often too demanding for clinicians and researchers without a computational background. Another problem represents the reproducibility of computational analyses across separated computational centres with inconsistent versions of installed libraries and bioinformatics tools.

WarpSTR: determining tandem repeat lengths using raw nanopore signals.

Motivation: Short tandem repeats (STRs) are regions of a genome containing many consecutive copies of the same short motif, possibly with small variations. Analysis of STRs has many clinical uses but is limited by technology mainly due to STRs surpassing the used read length. Nanopore sequencing, as one of long-read sequencing technologies, produces very long reads, thus offering more possibilities to study and analyze STRs.

SWSPM: A Novel Alignment-Free DNA Comparison Method Based on Signal Processing Approaches.

Computing similarity between 2 nucleotide sequences is one of the fundamental problems in bioinformatics. Current methods are based mainly on 2 major approaches: (1) sequence alignment, which is computationally expensive, and (2) faster, but less accurate, alignment-free methods based on various statistical summaries, for example, short word counts. We propose a new distance measure based on mathematical transforms from the domain of signal processing.
