Summary

Implements the phraya filter CLI command to read .phraya files, apply threshold filters, and output in VCF/TSV/phraya formats.

Implementation Details

  • Added Filter subcommand to phraya-cli with options for min-coverage, max-coverage, min-mapq, max-mapq
  • Integrates with existing phraya-filter library for threshold-based filtering
  • Supports multiple output formats: VCF (default), TSV, and filtered .phraya (for chaining)
  • Logs filter statistics to stderr ("Filtered X → Y observations")
  • Returns non-zero exit code on errors

Test Results

  • 9/13 integration tests passing
  • 4 tests failing related to threshold filtering validation
    • min-coverage filtering
    • min-mapq filtering
    • multiple thresholds (AND logic)
    • empty result filtering

All passing tests validate:

  • VCF/TSV/phraya output formats
  • File creation and readability
  • Command-line argument parsing
  • Error handling

Notes

The failing tests suggest either a subtle issue with how thresholds are applied or a mismatch between test expectations and implementation. Further investigation needed to resolve the 4 failing assertions.

Add 13 acceptance tests covering:
- Basic VCF output (default format)
- Threshold filtering (min-coverage, min-mapq)
- Multiple output formats (VCF, TSV, phraya)
- Filter chaining (phraya → filter → phraya)
- Statistics logging to stderr
- Error handling (nonexistent files, invalid arguments)
- Edge cases (empty results, position ordering)

All tests marked as RED (failing) since filter subcommand doesn't exist yet.
Tests use integration_test_filter.rs pattern with temp files and cargo run.
