Description

Updates all nf-core modules and subworkflows to their latest upstream versions (except subread, see details below)
and reconciles the resulting call-signature changes across the pipeline. No intended change in pipeline behavior. This implements Issue 447

What changed and why

  • Updated all nf-core modules and subworkflows to their latest available revisions using:

    nf-core modules update --all --no-preview --update-deps
    nf-core subworkflows update --all --no-preview --update-deps
    

    The resulting main.nf, meta.yml, and nf-test snapshot changes were retained, and the required ATAC-seq call sites were reconciled with the updated input and output signatures.

  • Reconciled call sites in workflows/atacseq.nf and the affected
    subworkflows/local/* and subworkflows/nf-core/* to the updated signatures.

  • Updated versions topic, but kept MultiQC version reporting as a named output rather than publishing it
    to the versions topic, avoiding a self-dependency because MultiQC consumes
    the collated version information as an input.

  • Add read groups to Chromap alignments, which Picard 3.4.0 MarkDuplicates now requires.

  • Pin subread to 2.0.1 so consensus peak counting keeps supporting mixed single-end/paired-end cohorts in a single featureCounts invocation.

  • Sort the consensus featureCounts BAM inputs so the count matrix column order is deterministic.

Verification:

Real-data A/B testing against dev was completed on AWS Batch using two
four-sample datasets.

  • Osmotic SRR (four-sample public subset): both runs produced the same
    72-process DAG and executed 185 tasks. MULTIQC completed as the terminal
    node in both runs, confirming resolution of the previous topic-channel
    deadlock on a second dataset. Scientific outputs are near-identical. The
    only differences are ±2 peaks in the two lowest-depth libraries, which
    have only single- or double-digit peak counts. Higher-signal samples are
    bit-identical.
  • HIV MDDC (GRCh38, four samples from PubMed ID 31968263): Outputs are bit-identical:
    every per-library and per-replicate peak count and FRiP score matches to
    full precision. Per-library peak counts are 30,438 / 35,854 / 36,551 /
    51,633, with FRiP scores of 0.216448 / 0.230010 / 0.198316 / 0.250963.
    The merged-library and merged-replicate consensus peak sets are also
    identical at 74,895 and 115,880 peaks, respectively.

I'm going to keep this PR in draft mode while I work on getting nf-test to pass

Bump every nf-core module and subworkflow via `nf-core modules update --all`
/ `nf-core subworkflows update --all` and reconcile the resulting
call-signature changes in first-party code. No intended behaviour change.

- Reconcile call sites in workflows/atacseq.nf and the affected
  subworkflows/{local,nf-core}/*.
- Fix the ch_fasta_fai reference channel: add .first() so the genome
  reference broadcasts to every sample instead of being consumed once.
- Consolidate singleton reference-channel plumbing.
- Remove the orphaned custom/getchromsizes module, replaced by
  SAMTOOLS_FAIDX(..., get_sizes=true).
- Fix a terminal MultiQC hang: MultiQC must not publish to the `versions`
  topic because its own input depends on that topic being resolved, which
  creates a cycle that leaves the run hanging forever. Emit the version as
  a named output instead, matching the nf-core/multiqc convention.
- Replace fragile '2>&1 | tr | sed;sed' version extraction in local modules
  with concise single-command forms (still emitting topic: versions).
- Ignore a merge_markers false positive in the bowtie2 test snapshot: SAM
  base-quality strings contain runs of '<' that trip the check.
Chromap BAMs carried no @rg header, so Picard 3.4.0 MarkDuplicates aborted
with a NullPointerException (SAMRecord.getReadGroup() is null) once the
module update bumped Picard from 3.1.1.

Update the fastq_align_chromap subworkflow to d92e0f8, which adds
PICARD_ADDORREPLACEREADGROUPS and an update_readgroups input, install the
picard/addorreplacereadgroups module, enable read-group updating at the
call site in workflows/atacseq.nf, and configure the process in
conf/modules.config to mirror the existing BWA/Bowtie2 read-group mapping
(RGID=meta.id technical id, RGSM=biological sample, RGPL=ILLUMINA,
RGLB=meta.id, RGPU=1, RGCN=params.seq_center).

The linked bam_sort_stats_samtools dependency tree also advanced samtools
1.23.1 -> 1.24 as part of the subworkflow update.
The module update bumped subread to 2.1.1, which strictly validates library
pairing per BAM: it rejects single-end reads when run in paired mode (-p) and
rejects paired-end reads when run in single-end mode. Consensus-peak
quantification passes a mixed single-end/paired-end cohort to one
SUBREAD_FEATURECOUNTS invocation, so 2.1.1 aborts with "No paired-end reads
were detected in paired-end read library".

Pin subread back to 2.0.1, which auto-detects pairing per BAM in a single
invocation and reproduces the read/fragment counts the existing snapshots
encode. This keeps the fix free of custom SE/PE-splitting and matrix-merging
code. Remove the pin once mixed-library counting is handled explicitly
(follow-up).

The pin makes the local module diverge from its registry git_sha, so it is
recorded as a tracked nf-core module patch (container + environment.yml) for
`nf-core modules lint` check_local_copy.
… order

The consensus BAM list is assembled from an unordered channel collect, so the
featureCounts invocation received its BAMs (and emitted its count columns) in a
run- and host-dependent order. The counts were identical, but the output file's
byte content - and therefore its snapshot md5 - varied between runs, making the
consensus featureCounts snapshot non-reproducible.

Sort the BAM list by filename before featureCounts so the column order (and the
output file) is deterministic and identical on any x86_64 host, matching CI.
…ates metrics

Regenerate all 7 pipeline nf-test snapshots against the updated modules
(subread 2.0.1 pin, samtools bumps, chromap read-group path, deterministic
consensus featureCounts column order). The previous snapshots were ~2 months
stale, from before the module update. Generated on GitHub-hosted ubuntu-latest
x86_64 runners via the update-snapshots workflow, so container digests and
architecture match CI.

Also extend .nftignore: Picard MarkDuplicates metrics headers carry a per-run
"Started on: <timestamp>" line, so their md5 is never reproducible. The
existing pattern only covered the default filename
(*.MarkDuplicates.metrics.txt), but this pipeline renames them via ext.prefix
to *.mkD.sorted.metrics.txt (library) and *.mRp.clN.sorted.metrics.txt
(replicate). These were the only non-deterministic files left once the
consensus featureCounts inputs were sorted.
Merge the nf-core/tools 4.0.3 template output (the same content as nf-core#449) so
this branch lints clean against the current template rather than carrying
files_unchanged exemptions for the pre-existing drift in
.github/PULL_REQUEST_TEMPLATE.md and the two logo PNGs.

Keeps the branch-local .nf-core.yml entries (bowtie2 snapshot merge_markers
false positive, bamtools filter config defaults) and regenerates
ro-crate-metadata.json. Drop this commit if nf-core#449 lands on dev first.

This PR depends on PR #449 merging first, so I'll keep it in a draft mode until then. Commit e1dc032 duplicates PR #449. It's what's keeping nf-core green right now, so I'll leave it until 449 actually merges, then rebase it out.

…ing subread

featureCounts (subread >= 2.1.0) applies paired-end mode (-p) per invocation and
aborts when one invocation mixes single-end and paired-end BAMs. The consensus
BAMs can span both library types, so split them by endedness, count each
homogeneous batch with the correct pairing flag, then merge the per-batch
matrices into a single consensus table for DESeq2 and MultiQC.

The joined tuple arity differs between the two instantiations of this
subworkflow: the merged-library caller carries a control-BAM column
([ meta, bam, control, peak ]) while the merged-replicate caller does not
([ meta, bams, peak ]). Index positionally to stay tolerant of both shapes, as
the pre-split implementation did.

The split replaced the single sorted BAM list from nf-core#448 with two per-endedness
batches plus a merge step, each assembled from an unordered channel collect, so
all three are sorted by filename. Without that the featureCounts column order,
the merged matrix and its snapshot md5 stop being reproducible across runs and
hosts — the guarantee nf-core#448 established.

Gating is unchanged: the join with ch_peaks keeps only samples that contributed
peaks, and combining with MACS3_CONSENSUS.out.saf still requires a consensus to
exist (>= 2 samples).

One thing I discovered while doing this:

  workflows/atacseq.nf:11   include { MULTIQC } from '../modules/local/multiqc'   ← what actually runs

  modules/local/multiqc.nf        multiqc 1.13   (dev: 1.13 — unchanged by 448)
  modules/nf-core/multiqc/        dev: 1.34  →  448: 1.35   ← installed, never included anywhere

So the pipeline runs a hand-rolled local MultiQC module pinned at 1.13, while the nf-core module sits in the tree unused. dev was already in exactly this state, and so I haven't changed anything, but I think there should be a follow-up issue to update multiqc.

seq_center is free text in the schema, so a value containing whitespace was
split by the shell. On the Chromap path this reached Picard
AddOrReplaceReadGroups as `--RGCN Broad Institute`, and Picard took `Broad` as
the value and rejected the remainder:

    Illegal argument value: Positional arguments were provided ',Institute}'
    but no positional argument is defined for this tool.

Reproduced against the picard 3.4.0 container this PR pins. Quoting the value
makes Picard receive it as a single argument.

Bowtie2 built `--rg CN:${params.seq_center}` the same way and had the same
defect; quoted too. BWA is unaffected because input_check.nf embeds the quotes
in meta.read_group at construction.

No test set seq_center, which is why the matrix stayed green over this. The
Chromap pipeline test now sets a value containing whitespace, so the path is
covered.
The updated subread module publishes *.featureCounts.tsv (and .tsv.summary);
the docs still described *.featureCounts.txt. Drop the matching .nftignore
patterns rather than renaming them: they are dead, and leaving the .tsv files
hashed by the pipeline snapshots is what gives the deterministic column order
useful coverage.

Applying the 4.0.3 template merge took nf-core-bot's RO-Crate wholesale, and the
bot generates its copy from the *template* README. That replaced the pipeline's
description with template boilerplate carrying "TODO nf-core" placeholders --
13,620 characters of real documentation down to 7,179.

Regenerate with `nf-core pipelines rocrate` so the file derives from this
repository's README instead. Verified: real description restored, 36 nodes, all
6 UUID @id references resolve, no dangling ids.

This makes the PR correct on its own rather than relying on a later template
merge to repair it.

The split replaced the single sorted BAM list from nf-core#448 with two per-endedness
batches plus a merge step, each assembled from an unordered channel collect, so
all three are sorted by filename. Without that the featureCounts column order,
the merged matrix and its snapshot md5 stop being reproducible across runs and
hosts — the guarantee nf-core#448 established.

Gating is unchanged: the join with ch_peaks keeps only samples that contributed
peaks, and combining with MACS3_CONSENSUS.out.saf still requires a consensus to
exist (>= 2 samples).
