Installation

Quick Install

# Copy plugin to Geneious plugins directory
cp /Users/dho/Documents/geneious-plugin-fastp/build/FastpPlugin.gplugin \
   ~/Library/Application\ Support/Geneious\ Prime/plugins/

# Restart Geneious Prime

Verification

After restarting Geneious:

  1. Go to Tools → Plugins
  2. Look for "Fastp Quality Control Plugin" in the list
  3. Check toolbar for "Run Fastp QC" button
  4. Right-click on a sequence list → "Run Fastp QC" should appear

Usage Quick Start

  1. Import FASTQ files into Geneious
  2. Select one or more sequence lists
  3. Click "Run Fastp QC" (toolbar or right-click menu)
  4. Configure options (or use defaults):
    • Tool selection: Auto-detect (recommended)
    • Quality filtering: Default settings are sensible
    • Adapter trimming: Auto-detect enabled
    • Threading: 4-8 threads for best performance
  5. Click OK to run
  6. View results:
    • Filtered sequences appear in Document Table
    • Statistics visible in Info tab
    • HTML report path logged to console

Testing Recommendations

Basic Functionality Tests

  1. Single-End Short Reads

    • Import a short-read FASTQ file (<1000bp average)
    • Run with default settings
    • Verify fastp is used (auto-detect)
    • Check output has metadata

  2. Paired-End Short Reads

    • Import two files: sample_R1.fastq, sample_R2.fastq
    • Run with default settings
    • Verify pairing is detected
    • Verify paired-end options are active
    • Check both R1 and R2 are processed

  3. Long Reads

    • Import a long-read FASTQ (PacBio/Nanopore, >1000bp average)
    • Run with default settings
    • Verify fastplong is used (auto-detect)
    • Check output quality

  4. Batch Processing

    • Select 3-5 different sequence lists
    • Run with default settings
    • Verify each is processed individually
    • Verify each output has separate metadata

Parameter Testing

  1. Quality Filtering

    • Set high quality threshold (phred 25)
    • Verify fewer reads pass filtering
    • Check Q20/Q30 rates increase in output

  2. Length Filtering

    • Set min length to 100bp
    • Verify reads <100bp are removed
    • Check output length distribution

  3. Adapter Trimming

    • Use data with known adapters
    • Enable auto-detect
    • Verify adapters are detected (check HTML report)
    • Verify adapters are removed

  4. Custom Adapters

    • Disable auto-detect
    • Enter custom adapter sequence
    • Verify custom adapter is used

  5. UMI Processing

    • Use UMI-containing data
    • Enable UMI processing
    • Configure UMI location and length
    • Verify UMIs are extracted

  6. Deduplication

    • Enable deduplication
    • Verify duplicate reads are removed
    • Check duplication rate in metadata

Error Handling Tests

  1. Invalid Input

    • Try running on non-FASTQ documents
    • Verify appropriate error message

  2. Cancelled Operation

    • Start processing
    • Click Cancel during execution
    • Verify process stops gracefully

  3. Invalid Parameters

    • Try invalid adapter sequences (non-ATGCN)
    • Verify validation error message

Performance Tests

  1. Large Files

    • Test with files >1GB
    • Monitor progress updates
    • Check memory usage

  2. Threading

    • Test with 1, 4, 8, and 16 threads
    • Compare processing times
    • Verify all produce identical results

Known Limitations

Platform Support

  • Current: macOS only (universal binary)
  • Planned: Linux and Windows in future versions

HTML Report Display

  • HTML reports are generated by fastp
  • Currently logged to console (file path)
  • Not imported into Geneious as documents
  • Planned for future version

Quality Score Handling

  • Plugin can handle sequences with or without quality scores
  • Generates default Phred 40 if quality missing
  • Some Geneious API quality methods may have limited support

File Naming for Paired-End

  • Relies on standard naming conventions (_R1/_R2, _1/_2)
  • Files with non-standard names may not be paired automatically
  • Users can rename files to match conventions

Future Enhancements

Short Term (Next Release)

  • Linux x86_64 binary support
  • Windows x64 binary support
  • HTML report import and display in Geneious
  • Parameter preset buttons (RNA-seq, WGS, Amplicon)
  • Simple/Advanced mode toggle

Medium Term

  • Batch processing optimization
  • Custom parameter profiles (save/load)
  • Integration with Geneious workflows
  • Multi-sample reports (comparing multiple runs)
  • Advanced QC plots

Long Term

  • Cloud execution support
  • Integration with public QC databases
  • Machine learning-based parameter suggestions
  • Real-time quality monitoring
  • Support for additional QC tools
