Module 1: Foundations of RNA Biology and Data Types

  • Select appropriate RNA sequencing protocols (e.g., total RNA-seq, small RNA-seq, long-read sequencing) based on target RNA classes and biological questions.
  • Evaluate trade-offs between sequencing depth and read length when profiling low-abundance transcripts or splice variants.
  • Integrate metadata standards (e.g., MIAME, MINSEQE) into experimental design to ensure reproducibility and data reuse.
  • Assess quality of RNA input using RIN (RNA Integrity Number) and adjust library preparation protocols accordingly.
  • Choose between poly-A selection and ribosomal RNA depletion based on sample type and transcript targets.
  • Implement spike-in controls for normalization in differential expression analyses involving degraded or limited samples.
  • Define criteria for batch effect detection when combining datasets from different labs or platforms.

Module 2: Preprocessing and Quality Control of RNA-seq Data

  • Configure adapter trimming tools (e.g., Trimmomatic, Cutadapt) with sequence-specific parameters to preserve non-polyA transcript ends.
  • Set quality score thresholds and read length cutoffs that balance data retention with downstream alignment accuracy.
  • Diagnose strandedness issues in alignment outputs by analyzing antisense read distributions across known gene bodies.
  • Implement FastQC and MultiQC pipelines in continuous integration workflows for automated QC reporting.
  • Adjust base quality recalibration parameters when working with FFPE or single-cell RNA-seq data.

  • Validate technical reproducibility using PCA and correlation matrices on raw count matrices before normalization.

Module 3: Transcriptome Assembly and Quantification

  • Select de novo assemblers (e.g., Trinity, SOAPdenovo-Trans) versus reference-guided tools (e.g., StringTie, Cufflinks) based on species annotation availability.
  • Optimize k-mer size and coverage cutoffs in de novo assembly to reduce fragmentation and chimeric transcripts.
  • Resolve isoform ambiguity using expectation-maximization algorithms in tools like Salmon or kallisto with proper bias correction.
