Introduction RNA-seq data from metatranscriptomics NGS projects contains both coding and non-coding types of RNAs. Before any gene expression or taxonomic analysis, it is important to separate reads in families of messenger RNAs and ribosomal RNAs (rRNAs). SortMeRNA, first released in 2012, is a fast and accurate tool for filtering ribosomal RNAs in metatranscriptomics datasets. The core algorithm is based

Introduction A common preprocessing step in metagenomics data analysis e.g. working with host-associated studies is to remove the host-related DNA from the sequencing data. This is often referred to as contamination removal. A common approach to isolate host-related reads is performing a read mapping against the host genome. Bowtie2 is the reference tool for this task. Since OmicsBox 2.0 this

Introduction The IsoSeq sequencing method produces full-length transcripts using Single Molecule, Real-Time (SMRT) Sequencing. Long read lengths allow sequencing of full-length transcripts up to 10 kb or longer, removing the need for transcript assembly or inferencing. Therefore, unlike traditional short-read methods, IsoSeq provides a more accurate and complete view of gene expression and alternative splicing events. This comprehensive understanding of

This article describes how to run CloudBlast wisely. OmicsBox allows you to perform NCBI Blast searches using a cloud system for high-performance computing. This system runs jobs in parallel and autoscales depending on demand. To control usage we use so-called CloudUnits. These units represent computation time (cpu seconds) on the AWS infrastructure. At the moment only Blast and InterProScan consume
