Comparing taxonomic and functional compositions between metagenomic samples

Any annotation of metagenomic sequences, whether it involves pathways, clusters of orthologous genes, species or any other taxonomic or functional classification can be compared across samples. These analyses are encompassed within the Differential Abundance Analysis, and they require robust statistical approaches to achieve reliable results because metagenomics datasets often show under-sampling and low signal-to-noise ratios. All differential abundance analyses can

Exploring transcriptome completeness in OmicsBox with BUSCO

De novo transcriptome assemblies are required to analyze RNA-seq data from a species for which there is no reference genome. Once the assembly is complete, researchers need to know how good it is or compare the quality of similar assemblies generated by different parameters. There are several ways to characterize the quality of transcriptome assemblies. A good metric of assembly

Predict coding regions within transcripts in OmicsBox with TransDecoder

Most transcripts assembled from eukaryotic and prokaryotic RNA-Seq data are expected to code for proteins. The most practical procedure to identify likely coding transcripts is a sequence homology search, such as by BLASTX, against sequences from a well-annotated and related species. Predicting coding regions is crucial to determine the molecular role that transcripts play in the cell. Unfortunately, such well-annotated

Hybrid Genome Assembly in OmicsBox with SPAdes

DNA sequencing is the process of determining the nucleic acid sequence in DNA, and it is the technology by which the genome of a species can be characterized. Despite the advent of next-generation sequencing, current DNA sequencing technologies cannot read whole genomes at once, but rather reads small pieces of between 20 and 30.000 bases, depending on the technology used.

How to run Blast of the differential expressed genes?

It is possible to run Blast only on the differential expressed genes and not on all the data with OmicsBox. One has to select only those sequences that have differential expressed genes in the OmicsBox project.First,  make sure that the name of the sequences in the project match the ones from the differential expression results.
