================================================================================
STEP 1: LOADING STAR-FUSION PREDICTIONS
================================================================================
Loading STAR-Fusion predictions from: 659_ecd-T1-TRNA-1_B23MHV2LT4_1.starfusion.starfusion.fusion_predictions.tsv
  ✓ Loaded: 2734 fusions

================================================================================
STEP 2: CONVERTING TO BREAKPOINT_ID FORMAT
================================================================================
⚠ Warning: 1 rows have invalid breakpoint_ID (will be skipped in blacklist flagging)
✓ Converted to breakpoint_ID format: 2733 valid, 1 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 278 of 2734 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 136 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: 80 pass (CALL=1), 2654 fail (CALL=0)
  Total fusions: 2734 (all rows retained)
  Added FILTER column: PASS=80, FAIL=2654

✓ Verified: All 327 blacklisted fusions have CALL=0

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

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

Total fusions: 2734
  Pass (CALL=1): 80 (2.9%)
  Fail (CALL=0): 2654 (97.1%)

Blacklist Flagging:
  Total blacklisted: 327
  ✓ All 327 blacklisted fusions have CALL=0

Failure Reasons (top 10):
  Read count too low: 1 < 8: 1712
  Excluded SpliceType: INCL_NON_REF_SPLICE: 451
  Blacklisted: 191
  Blacklisted; aih_curated_blacklist score(3): 87
  Read count too low: 2 < 8: 76
  aih_curated_blacklist score(3): 45
  Excluded annotation pattern: HGNC_GENEFAM: 29
  Read count too low: 3 < 8: 16
  Does not meet inclusion criteria: 15
  Read count too low: 5 < 8: 8

Breakdown by SpliceType:
  INCL_NON_REF_SPLICE: 1 pass, 912 fail (total: 913)
  NO_JUNCTION_READS_IDENTIFIED: 0 pass, 1 fail (total: 1)
  ONLY_REF_SPLICE: 79 pass, 1741 fail (total: 1820)

Read Count Statistics:
  Fusions with < 3 total reads: 2456
  Of these, 2456 have CALL=0

================================================================================
STEP 6: EXPORTING RESULTS
================================================================================
✓ Results exported to: 659_ecd-T1-TRNA-1_B23MHV2LT4_1.starfusion.starfusion.fusion_predictions.filtered.tsv
  Total fusions: 2734
  CALL=1 (pass): 80
  CALL=0 (fail): 2654
✓ Passing fusions (CALL=1) exported to: 659_ecd-T1-TRNA-1_B23MHV2LT4_1.starfusion.starfusion.fusion_predictions.filtered_pass_only.tsv
✓ Summary exported to: 659_ecd-T1-TRNA-1_B23MHV2LT4_1.starfusion.starfusion.fusion_predictions.filter_summary.txt
