COMAN

COMAN performs comprehensive analysis of metatranscriptomic sequencing data to provide functional annotation, comparative statistical analysis, pathway enrichment, and co-expression network analysis for microbial community functional profiling.

Key Features:

• Automated pipeline: Executes a sequence of computational steps including quality control, non-coding RNA removal, functional annotation, comparative statistics, pathway enrichment, and co-expression network construction.
• Quality Control: Processes raw sequencing reads to remove low-quality reads and artifacts before downstream analysis.
• Non-coding RNA removal: Filters out non-coding RNA sequences prior to functional annotation.
• Functional annotation: Assigns biological functions to transcripts to characterize gene expression patterns.
• Comparative statistical analysis: Identifies significant differences in transcript abundance between samples or conditions.
• Pathway enrichment analysis: Detects overrepresented metabolic and regulatory pathways from annotated transcripts.
• Co-expression network analysis: Constructs networks of co-expressed genes to reveal potential interactions and functional modules.
• Data output: Produces tabular outputs and high-quality visualizations for interpretation and downstream integration.

Scientific Applications:

• Microbial community functional profiling: Derives functional profiles from metatranscriptomic reads to assess community activity.
• Comparative metatranscriptomics: Compares transcript abundance across samples or conditions to identify differential expression.
• Pathway activity inference: Infers active metabolic and regulatory pathways via pathway enrichment analysis.
• Interaction and module discovery: Reveals gene modules and potential microbial interactions through co-expression networks.
• Clinical and environmental microbiota studies: Applies metatranscriptomic analyses to investigate microbial roles in clinical and environmental contexts.

Methodology:

Quality control of raw sequencing reads, removal of non-coding RNA sequences, functional annotation of transcripts, comparative statistical analysis, pathway enrichment analysis, and co-expression network construction.
