================================================================================
STEP 1: LOADING STAR-FUSION PREDICTIONS
================================================================================
Loading STAR-Fusion predictions from: SkinN_FFPE_L08_RNA_01_B23LG7FLT4_1.starfusion.starfusion.fusion_predictions.tsv
  ✓ Loaded: 317 fusions

================================================================================
STEP 2: CONVERTING TO BREAKPOINT_ID FORMAT
================================================================================
✓ Converted to breakpoint_ID format: 317 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 32 of 317 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 35 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), 317 fail (CALL=0)
  Total fusions: 317 (all rows retained)
  Added FILTER column: PASS=0, FAIL=317

✓ Verified: All 48 blacklisted fusions have CALL=0

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

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

Total fusions: 317
  Pass (CALL=1): 0 (0.0%)
  Fail (CALL=0): 317 (100.0%)

Blacklist Flagging:
  Total blacklisted: 48
  ✓ All 48 blacklisted fusions have CALL=0

Failure Reasons (top 10):
  Excluded SpliceType: INCL_NON_REF_SPLICE: 194
  Read count too low: 1 < 8: 57
  Blacklisted; aih_curated_blacklist score(3): 19
  aih_curated_blacklist score(3): 16
  Blacklisted: 13
  Read count too low: 2 < 8: 10
  Excluded annotation pattern: HGNC_GENEFAM: 5
  Read count too low: 3 < 8: 2
  Excluded annotation pattern: GTEx_recurrent_StarF2019: 1

Breakdown by SpliceType:
  INCL_NON_REF_SPLICE: 0 pass, 240 fail (total: 240)
  ONLY_REF_SPLICE: 0 pass, 77 fail (total: 77)

Read Count Statistics:
  Fusions with < 3 total reads: 308
  Of these, 308 have CALL=0

================================================================================
STEP 6: EXPORTING RESULTS
================================================================================
✓ Results exported to: SkinN_FFPE_L08_RNA_01_B23LG7FLT4_1.starfusion.starfusion.fusion_predictions.filtered.tsv
  Total fusions: 317
  CALL=1 (pass): 0
  CALL=0 (fail): 317
✓ Empty pass_only file created (no passing fusions): SkinN_FFPE_L08_RNA_01_B23LG7FLT4_1.starfusion.starfusion.fusion_predictions.filtered_pass_only.tsv
✓ Summary exported to: SkinN_FFPE_L08_RNA_01_B23LG7FLT4_1.starfusion.starfusion.fusion_predictions.filter_summary.txt
