================================================================================
STEP 1: LOADING STAR-FUSION PREDICTIONS
================================================================================
Loading STAR-Fusion predictions from: BVT_FFPE_TRNA_bst_04_A23WKFTLT4_3.starfusion.starfusion.fusion_predictions.tsv
  ✓ Loaded: 1504 fusions

================================================================================
STEP 2: CONVERTING TO BREAKPOINT_ID FORMAT
================================================================================
✓ Converted to breakpoint_ID format: 1504 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 109 of 1504 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 83 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: 22 pass (CALL=1), 1482 fail (CALL=0)
  Total fusions: 1504 (all rows retained)
  Added FILTER column: PASS=22, FAIL=1482

✓ Verified: All 153 blacklisted fusions have CALL=0

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

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

Total fusions: 1504
  Pass (CALL=1): 22 (1.5%)
  Fail (CALL=0): 1482 (98.5%)

Blacklist Flagging:
  Total blacklisted: 153
  ✓ All 153 blacklisted fusions have CALL=0

Failure Reasons (top 10):
  Read count too low: 1 < 8: 668
  Excluded SpliceType: INCL_NON_REF_SPLICE: 545
  Blacklisted: 70
  Read count too low: 2 < 8: 64
  aih_curated_blacklist score(3): 43
  Blacklisted; aih_curated_blacklist score(3): 39
  Excluded annotation pattern: HGNC_GENEFAM: 26
  Read count too low: 3 < 8: 15
  Read count too low: 7 < 8: 3
  Read count too low: 4 < 8: 3

Breakdown by SpliceType:
  INCL_NON_REF_SPLICE: 2 pass, 761 fail (total: 763)
  ONLY_REF_SPLICE: 20 pass, 721 fail (total: 741)

Read Count Statistics:
  Fusions with < 3 total reads: 1433
  Of these, 1433 have CALL=0

================================================================================
STEP 6: EXPORTING RESULTS
================================================================================
✓ Results exported to: BVT_FFPE_TRNA_bst_04_A23WKFTLT4_3.starfusion.starfusion.fusion_predictions.filtered.tsv
  Total fusions: 1504
  CALL=1 (pass): 22
  CALL=0 (fail): 1482
✓ Passing fusions (CALL=1) exported to: BVT_FFPE_TRNA_bst_04_A23WKFTLT4_3.starfusion.starfusion.fusion_predictions.filtered_pass_only.tsv
✓ Summary exported to: BVT_FFPE_TRNA_bst_04_A23WKFTLT4_3.starfusion.starfusion.fusion_predictions.filter_summary.txt
