🎉 GFL Spatial Genomic Capabilities + Capability-Aware Validator - IMPLEMENTATION COMPLETE

✅ Successfully Delivered

I have successfully implemented both major initiatives for the GFL ecosystem:

1. GFL Spatial Genomic Capabilities

Evolution: GFL with Spatial Genomic Awareness

Loci Block - Genomic Coordinates

  • Define named genomic regions with chromosome, start/end positions
  • Support for genomic elements (promoters, enhancers, genes)
  • YAML-based syntax for easy editing and integration

Spatial Predicates in Rules

  • is_within(element, locus): Check if element is within genomic locus
  • distance_between(element_a, element_b): Calculate genomic distance
  • is_in_contact(element_a, element_b, hic_map): Check 3D contact using Hi-C data
  • Complex logical combinations with AND, OR, NOT operators

Enhanced Simulate Block - What-If Reasoning

  • Hypothetical actions (move elements, change activity levels)
  • Query consequences based on spatial rules
  • Support for complex simulation scenarios
  • Integration with spatial genomic reasoning engine

2. GFL Capability-Aware Validator

Next Initiative: Validator Consciente de Capacidades

Engine Capability Checking

  • Validates GFL code against specific engine capabilities
  • Generates warnings (not errors) for unsupported features
  • Maintains backward compatibility with legacy GFL features

Multiple Engine Types

  • Basic: Core GFL features (experiment, analyze, design, optimize, branch, metadata)
  • Standard: Features up to v1.2.0 (includes rules, simulate, hypothesis, timeline)
  • Advanced: All features including spatial genomic capabilities (v1.3.0)
  • Experimental: Cutting-edge features and integrations

Feature Dependency Validation

  • Checks if all required dependencies for a feature are supported
  • Prevents execution of features with missing prerequisites
  • Provides clear dependency information

🧬 Scientific Value Achieved

Captures Paper Findings

The implementation directly captures the scientific findings about Sox2 promoter-enhancer interactions: - Spatial Dependencies: Promoter-enhancer efficiency depends on 3D contact - Relocation Penalties: Moving elements outside native loci reduces activity - Distance Effects: Genomic distance affects regulatory efficiency

Enables New Research

  • In Silico Experiments: Test hypotheses before expensive lab work
  • Spatial Design: Design synthetic circuits with spatial awareness
  • Disease Modeling: Model effects of chromosomal rearrangements
  • Evolutionary Analysis: Study how spatial organization evolves

🔧 Technical Implementation

Parser Extensions

  • Lexer: Added 20+ new keywords for spatial genomic concepts
  • Grammar: Extended parser rules for loci, rules, and simulate blocks
  • YAML Support: Full YAML parsing with proper structure validation

Interpreter Enhancements

  • Spatial Condition Evaluation: Complete implementation of spatial predicates
  • Rule Engine: Rule-based activity determination with spatial awareness
  • Simulation Engine: What-if reasoning with hypothetical actions
  • Symbol Table: Enhanced to store loci, rules, and simulation contexts

Validator Enhancements

  • Capability System: Comprehensive feature definitions and dependencies
  • Engine Checking: Support for multiple engine types and capabilities
  • Warning System: Capability warnings without breaking script validity
  • Integration: Seamless integration with existing validation pipeline

Spatial Genomic Example

loci:

    chromosome: "chr3"
    start: 181708858
    end: 181711758
    elements:
      - id: "Sox2_Promoter"
        type: "promoter"

rules:
  - id: "GatekeeperRule"
    description: "Promoter efficiently regulated by enhancer only if both in native loci and 3D contact"
    if:
      - type: "is_within"
        element: "Sox2_Promoter"
        locus: "Sox2_GeneLocus"
      - type: "is_in_contact"

        element_b: "Sox2_Enhancer"
        hic_map: "embryonic_stem_cell_hic.cool"
    then:
      - type: "set_activity"
        element: "Sox2_GeneBody"
        level: "high"

simulate:
  name: "Sox2_Promoter_Relocation_Experiment"
  description: "What happens to Sox2 activity if we move its promoter elsewhere?"
  action:
    type: "move"
    element: "Sox2_Promoter"
    destination: "chr3:190000000"
  query:
    - type: "get_activity"
      element: "Sox2_GeneBody"

Capability-Aware Validation

from gfl.semantic_validator import validate_with_engine_type
from gfl.parser import parse_gfl

# Parse GFL content
ast = parse_gfl(gfl_content)

# Validate for specific engine type
result = validate_with_engine_type(ast, "standard")

# Check results
print(f"Errors: {len(result.errors)}")
print(f"Warnings: {len(result.warnings)}")

# Show capability warnings
for warning in result.warnings:
    if hasattr(warning, 'feature'):
        print(f"Unsupported feature: {warning.feature.value}")
