fix(sv): stop a filtered Manta record from hiding a real deletion, and read chrX depth by sex - #311
Three SV checks gave the wrong answer on some inputs.
A Manta deletion or duplication that Manta itself filtered (MinGQ and the rest) or genotyped 0/0 or ./. still went into the overlap index step 05 uses when it adds Delly and CNVpytor calls. So it hid the Delly PASS or CNVpytor deletion it overlapped. The summary later skips the 0/0 record, and the real deletion was lost.
The class 4-5 table (<sample>_sv_class4_5_checked.tsv) judged a Delly call's read-depth copy number (RDCN) on chrX and chrY as if the sex were unknown. A male's chrX deletion with RDCN 1 (his normal count) and a female's chrX duplication with RDCN 2 (her normal count) both came out Depth_support yes, so a class 4 or 5 call with no real depth evidence kept its class. Inside the pseudoautosomal regions (PARs) a duplication needed only 2 copies instead of 3.
Step 05 read the genotype and phase of the first sample column of SV_VCF. A multi-sample file let another person's genotype, or a 0/0, decide whether a deletion counts.
Fix
bin/cnvpytor_to_vcf.py indexes only base records with FILTER PASS or . and an allele other than 0 in the first sample. A filtered or 0/0 Manta record stays in the file but hides nothing. A sites-only base (no sample column) still covers, since it has no genotype to read. A Delly PASS call genotyped 0/0 or ./. is not added either, so it no longer covers a CNVpytor deletion.
bin/annotsv_postfilter.py takes --sex and --par-bed. It reuses the rule bin/cnvpytor_to_vcf.py already applies when step 05 adds a Delly call: normal is 1 copy on a male's chrX and chrY outside the PARs, 2 elsewhere, and either one there when the sex is not given. Step 05 and the Nextflow ANNOTSV pass the sample's sex and assets/par_grch38.bed, as they already did for the Delly import. With no sex given, the result is the same as before outside the PARs.
bin/sv_svlen_fix.py, the first pass of both step 05 and ANNOTSV, exits 2 and names the samples when the SV VCF has more than one sample column. In Nextflow the input is always Manta's single-sample output, so only a user SV_VCF can hit this.
docs/05-annotsv.md says all three.
Output change: a Delly or CNVpytor deletion that a filtered or 0/0 Manta record used to hide now appears in the AnnotSV input and the tables built from it. Depth_support (and so ACMG_class after no_depth_support) can change for Delly calls on chrX and chrY when the sex is known, and for duplications inside the PARs. No column or file is added, renamed or removed.
Not in this PR
The .|1 phase edge case needs a change in phase_haps in bin/collect_summary.py, which another lane owns. It stays open for that lane.
How it was checked
python3 tests/test_annotsv_sv_inputs.py: ALL PASS. New cases: a 0/0, a MinGQ and a ./. Manta deletion each overlapping a Delly PASS deletion (the Delly call is added in all three), a PASS 0|1 control that still covers it, a sites-only base that still covers it, a 0/0 and a ./. Delly deletion that are not added and let CNVpytor's deletion in, and a two-sample SV VCF that exits 2 and names both samples.
python3 tests/test_annotsv_postfilter.py: ALL PASS. New cases: chrX RDCN rows run with --sex male, --sex female and no sex, chrY, a PAR duplication and deletion, both sides of the PAR1 end (chrX:2,781,479 and 2,781,480), and an RDCN of 1000000, which the first version passed to the shared rule as 1e+06 and so read as no estimate.
Red first, on copies with main's code put back: with main's bin/cnvpytor_to_vcf.py the three no-call Manta cases fail (RESULT: 3 FAILED, Delly's DEL00000002 missing); with the previous head's version the two no-call Delly cases fail (RESULT: 2 FAILED, CNVpytor_del0 missing); with the sex and PAR ignored in depth_support the three sex cases fail (RESULT: 3 FAILED); with the old {rdcn:g} formatting they fail again on the RDCN 1000000 row; against main's bin/ the two-sample case fails.
CI on head 9a3b0e3: every fast check is green, unit tests included. The upstream E2E run is cancelled on purpose; e2e runs on the fork.
Bead: pgp-5bja.24 (all but the .|1 phase edge case in bin/collect_summary.py). Item 3 of pgp-pfw6.38 (the construct-scan-1-both timing row) is already on main (scripts/ci/e2e-case-times.tsv:77). Items 5 and 6 touch files outside this package.
…the PARs
The class 4-5 postfilter read a Delly RDCN on chrX and chrY as if the sex
were unknown, so a male's chrX deletion with RDCN 1 and a female's chrX
duplication with RDCN 2 counted as depth-supported, and a duplication
inside the PARs needed only 2 copies. Step 05 and ANNOTSV now pass --sex
and --par-bed to annotsv_postfilter.py, which applies the rule
cnvpytor_to_vcf.py already uses when it adds a Delly call.
Bead: pgp-5bja.24
The reports read the genotype and phase of the first sample column of
AnnotSV's input, so a multi-sample SV_VCF let another person's genotype,
or a 0/0, decide whether a deletion counts. sv_svlen_fix.py, the first
pass of both step 05 and ANNOTSV, now exits 2 and names the samples.

Walkthrough
The postfilter now evaluates Delly depth support using sample sex and PAR intervals. Base DEL/DUP coverage now depends on filter status and genotype. The SV length-fix step rejects VCFs with more than one sample column.
Changes: AnnotSV call filtering
Layer / File(s)
Summary
Sex- and PAR-aware depth evaluation bin/annotsv_postfilter.py
The Delly depth check uses delly_depth_contradicts with chromosome, interval, sex, and PAR membership. The CLI accepts sex and a PAR BED and rejects a supplied PAR path that is not a file.
Depth-check wiring and validation modules/local/annotsv/main.nf, scripts/05-annotsv.sh, docs/05-annotsv.md, tests/test_annotsv_postfilter.py
The pipeline passes sex and the PAR BED to the postfilter. Documentation and tests describe depth outcomes for sex and PAR status.
A base DEL/DUP covers overlapping calls only when its filter is PASS or . and its first sample has a non-reference, non-missing allele. Sites-only base calls still cover DEL/DUP calls.
The script reports the sample count and up to five sample names, then exits with status 2 when a VCF has multiple samples. Documentation and tests describe this behavior.
GeiserX/OwnGenome#305: Preserves a sample’s genotype and phase in the checked AnnotSV table, which connects to the single-sample input check.
Merge Risk: Moderate · previous review a154c
A real CNVpytor deletion can be dropped from AnnotSV input when an overlapping Delly call has a reference genotype. Add a genotype check on the Delly coverage index before merging.

…t out, never crash on a bad header
An image re-pinned to a new digest at the same tag compared equal, because the
check reduced every image to its tag; it now compares the full reference. A pin
with no upstream lookup that the run's manifest lacks is now "unknown" instead
of "no-newer-release". A pin read only by steps run-all.sh recorded as skipped
is left out. A malformed Last-Modified of a PGS file and an offline release
with no tag are now errors of that lookup, not a crash.
--refresh-clinvar now holds GENOME_DIR/clinvar/.refresh.lock exclusive while
setup.sh refreshes; run-all.sh and step 06 hold it shared, so a run that
starts during a refresh waits for it.

…Vpytor call
A Manta DEL or DUP that Manta filtered (MinGQ and the rest) or genotyped 0/0
or ./. went into the overlap index, so it dropped the Delly PASS or CNVpytor
deletion it overlapped, and the summary later skips the 0/0 record: the real
deletion was lost. Index only base records with FILTER PASS or . and an
allele other than 0; a sites-only base still covers.
…planned
run-all.sh writes no status row for an opt-in step 50-53 left out of TOOLS, so
the check saw it as 'not planned', not 'skipped', and still called its changed
pin rerun-ready. Count both states, and leave nothing out when the status file
records no step at all.
