OmicsBox Functional Analysis Module

The OmicsBox Functional Analysis Module is a comprehensive bioinformatics platform for the functional annotation and analysis of any sequencing data. Built on the internationally recognised Blast2GO methodology — first published in 2005 and cited in over 7,000 research publications — it is designed for researchers working with novel genomes, transcriptomes, and non-model organisms who need reliable, high-quality functional labels and downstream analytical capabilities in a single integrated environment.

The module enables users to load a FASTA file and work through the complete Blast2GO annotation pipeline step by step, with full control over all analysis parameters. All data and results are kept in one place, making it straightforward to move from raw sequences through to enrichment and pathway analysis without switching between tools. OmicsBox runs out of the box on standard PCs and laptops running Windows, Linux, or macOS.

Sequence Alignment and Domain Search

• CloudBlast for high-performance cloud-based sequence alignment
• BLAST against public NCBI databases or local custom databases, supporting all BLAST variations
• CloudInterProScan for fast protein domain and family searches in the cloud
• InterProScan via the public EMBL service as an alternative option
• EggNOG annotation executed in the high-performance cloud
• RFAM analysis for coding potential assessment
• Longest ORF prediction for novel sequence datasets

Gene Ontology Mapping and Annotation

• GO Mapping to link potential homologs and protein domains with functional annotation from up-to-date, well-curated UniProt and Gene Ontology consortium databases
• Blast2GO annotation methodology to flexibly assign the most reliable functional labels to novel sequences, taking into account source annotation quality and ontology hierarchies
• GO-Slim for condensed, high-level ontology summaries
• Enzyme Commission (EC) number annotation
• Full Gene Ontology annotation workflow using cloud-powered algorithms covering Biological Process, Molecular Function, and Cellular Component categories
• Detailed statistics generated at every step to summarise annotation results

Visualisation and Graph Tools

• GO graphs to provide a comprehensive overview of annotations across whole datasets
• Combined GO graphs integrating annotations from both BLAST and InterProScan results
• Specific and coloured GO graphs for targeted presentation of conclusions
• Convenient histograms and distribution charts to evaluate every stage of the analysis
• Filtering and shaping of GO graphs to highlight and communicate key findings

Enrichment Analysis

• Fisher Exact Test for identifying over- and under-represented molecular functions
• Gene Set Enrichment Analysis (GSEA) for more nuanced detection of enriched functional categories
• Integration of differential expression data with enrichment workflows

Pathway Analysis

• Identification of Reactome and KEGG pathways for any set of sequences
• Combined pathway enrichment calculation using differential expression data and GSEA
• KEGG and Reactome Pathway Browser for interactive exploration
• Result tables enabling filtering for enriched pathways linked to differentially expressed genes
• Combined visualisation to facilitate biological interpretation with ease

Data Management and Workflow Flexibility

• Sorting and filtering of whole datasets throughout the analysis
• Versatile import and export options supporting many file formats
• Support for multiple annotation strategies ranging from maximum fidelity to high-coverage and permissive approaches
• Applicable to non-model organism datasets, including RNA-Seq studies

The module has been benchmarked on large-scale datasets, demonstrating annotation of the whole tomato genome with 35,768 characterised genes, 80% high-quality annotations, and a processing time of approximately four hours. OmicsBox is available for evaluation via a free trial or a custom demo, and integrates seamlessly with other OmicsBox modules for a complete omics analysis experience.
