================================================================================
STEP 1: LOADING STAR-FUSION PREDICTIONS
================================================================================
Loading STAR-Fusion predictions from: HeadNeckN_FFPE_L03_RNA_01_B23LG7FLT4_1.starfusion.starfusion.fusion_predictions.tsv
  ✓ Loaded: 406 fusions

================================================================================
STEP 2: CONVERTING TO BREAKPOINT_ID FORMAT
================================================================================
✓ Converted to breakpoint_ID format: 406 valid, 0 invalid

================================================================================
STEP 3: FLAGGING WITH BLACKLIST
================================================================================
Loading blacklist (this may take a while)...
Loading blacklist from: blacklist_hg38_GRCh38_v2.4.0.tsv.gz
  Loaded 9381 single rules and 16721785 pair rules
  Indexed blacklist (bin_size=100000)
Flagging fusions with blacklist...
✓ Flagged 24 of 406 fusions as blacklisted

================================================================================
STEP 3b: AIH CURATED BREAKPOINT BLACKLIST
================================================================================
Loading AIH blacklist table from: blacklist_breakpoint_database_2026-04-27.tsv
  Qualified breakpoint keys (orientations): 1378
  AIH curated blacklist: matched 29 fusion rows (breakpoint_ID in qualified set)

================================================================================
STEP 4: APPLYING YAML-BASED FILTER
================================================================================
✓ Filter initialized from: starfusion_filter_config.yaml
Applying filter criteria (adding CALL column)...
✓ Filter applied: 0 pass (CALL=1), 406 fail (CALL=0)
  Total fusions: 406 (all rows retained)
  Added FILTER column: PASS=0, FAIL=406

✓ Verified: All 40 blacklisted fusions have CALL=0

================================================================================
STEP 5: GENERATING SUMMARY STATISTICS
================================================================================

================================================================================
FILTERING SUMMARY
================================================================================

Total fusions: 406
  Pass (CALL=1): 0 (0.0%)
  Fail (CALL=0): 406 (100.0%)

Blacklist Flagging:
  Total blacklisted: 40
  ✓ All 40 blacklisted fusions have CALL=0

Failure Reasons (top 10):
  Excluded SpliceType: INCL_NON_REF_SPLICE: 242
  Read count too low: 1 < 8: 103
  aih_curated_blacklist score(3): 16
  Blacklisted; aih_curated_blacklist score(3): 13
  Blacklisted: 11
  Read count too low: 2 < 8: 11
  Excluded annotation pattern: HGNC_GENEFAM: 8
  Read count too low: 3 < 8: 2

Breakdown by SpliceType:
  INCL_NON_REF_SPLICE: 0 pass, 295 fail (total: 295)
  ONLY_REF_SPLICE: 0 pass, 111 fail (total: 111)

Read Count Statistics:
  Fusions with < 3 total reads: 400
  Of these, 400 have CALL=0

================================================================================
STEP 6: EXPORTING RESULTS
================================================================================
✓ Results exported to: HeadNeckN_FFPE_L03_RNA_01_B23LG7FLT4_1.starfusion.starfusion.fusion_predictions.filtered.tsv
  Total fusions: 406
  CALL=1 (pass): 0
  CALL=0 (fail): 406
✓ Empty pass_only file created (no passing fusions): HeadNeckN_FFPE_L03_RNA_01_B23LG7FLT4_1.starfusion.starfusion.fusion_predictions.filtered_pass_only.tsv
✓ Summary exported to: HeadNeckN_FFPE_L03_RNA_01_B23LG7FLT4_1.starfusion.starfusion.fusion_predictions.filter_summary.txt

================================================================================
✓ FILTERING COMPLETE
