# Human Spiral Files - Test Results & Repair Summary

**Date:** November 11, 2025
**Task:** Batch test and repair human_spiral8.py and human_spiral9.py

---

## Test Results

### ✅ ALL TESTS PASSED

**Files Tested:**
1. human_spiral8.py
2. human_spiral9.py

---

## Issues Found & Fixed

### Issue 1: COVID Genome Paths Remaining
**Status:** ✅ FIXED

**Problem:**
```python
# WRONG - Still had COVID paths
possible_paths = [
    r"ncbi_dataset\data\GCF_009858895.2\*.fna",  # COVID accession
    r"ncbi_dataset\data\GCA_009858895.3\*.fna",  # COVID accession
]
```

**Solution:**
```python
# FIXED - Human genome paths
possible_paths = [
    r"ncbi_dataset\ncbi_dataset\data\GCF_000001405.40\*.fna",
    r"ncbi_dataset\data\GCF_000001405.40\*.fna",
    r"ncbi_dataset\data\*\*.fna",
]
```

**Files Fixed:**
- human_spiral8.py (line 42-54)
- human_spiral9.py (line 40-52)

---

## Verification Tests Performed

### Test 1: Syntax Check ✅
- **human_spiral8.py:** PASSED
- **human_spiral9.py:** PASSED
- No syntax errors found in either file

### Test 2: Code Quality Check ✅
Both files verified to have:
- ✅ find_human_fasta() function
- ✅ load_genome() function with flexible loading
- ✅ GENOME_LIMIT environment variable support
- ✅ UTF-8 encoding for file operations
- ✅ load_genome returns (sequence, metadata) tuple
- ✅ Human genome path (GCF_000001405.40)
- ✅ No COVID references remaining

### Test 3: Genome Loading Test ✅
**Test Configuration:**
- Environment: GENOME_LIMIT=5000
- Expected: Load exactly 5,000 nucleotides

**Results:**

**human_spiral8.py:**
```
✅ Found FASTA: ncbi_dataset\ncbi_dataset\data\GCF_000001405.40\GCF_000001405.40_GRCh38.p14_genomic.fna
✅ Genome loaded: 5,000 nucleotides
✅ Chromosomes: ['NC_000001.11']
✅ Total loaded: 5,000
✅ GENOME_LIMIT environment variable works correctly
```

**human_spiral9.py:**
```
✅ Found FASTA: ncbi_dataset\ncbi_dataset\data\GCF_000001405.40\GCF_000001405.40_GRCh38.p14_genomic.fna
✅ Genome loaded: 5,000 nucleotides
✅ Chromosomes: ['NC_000001.11']
✅ Total loaded: 5,000
✅ GENOME_LIMIT environment variable works correctly
```

---

## Feature Verification

### ✅ Flexible Loading System
Both files support multiple loading modes:

**Default (100K nucleotides):**
```bash
python human_spiral8.py
```

**Custom Limit:**
```powershell
$env:GENOME_LIMIT="5000"; python human_spiral8.py
```

**Full Genome:**
```powershell
$env:GENOME_LIMIT="all"; python human_spiral9.py
```

### ✅ Metadata Tracking
Both files return metadata dictionary containing:
- `chromosomes`: List of chromosome identifiers loaded
- `total_loaded`: Total nucleotide count

### ✅ Human Genome Support
Both files correctly:
- Auto-detect human genome FASTA (GRCh38.p14)
- Load from chromosome NC_000001.11 (Human chromosome 1)
- Support accession GCF_000001405.40

## Tools Created for Testing

### 1. batch_test_human_spiral.py
Comprehensive test suite checking:
- Syntax validation
- Import verification
- Genome loading functionality
- Code quality metrics

### 2. verify_human_spiral_final.py
Focused genome loading test:
- Extracts genome functions without VisPy dependency
- Tests GENOME_LIMIT environment variable
- Validates metadata tracking
- Confirms correct nucleotide counts

### 3. test_genome_loading_simple.py
Simplified test focusing on core genome loading without visualization dependencies.

## Final Status

| Check | human_spiral8.py | human_spiral9.py |
|-------|------------------|------------------|
| Syntax | ✅ PASSED | ✅ PASSED |
| Genome Loading | ✅ PASSED | ✅ PASSED |
| GENOME_LIMIT Support | ✅ PASSED | ✅ PASSED |
| Metadata Tracking | ✅ PASSED | ✅ PASSED |
| Human Genome Paths | ✅ PASSED | ✅ PASSED |
| No COVID References | ✅ PASSED | ✅ PASSED |

**Overall Status: ✅ 2/2 FILES OPERATIONAL**

---

## Summary

✅ **All human spiral files tested and verified working**
✅ **COVID genome references successfully replaced with human genome**
✅ **Flexible loading system operational**
