Add MacSyFinder modules for model management and protein system detection

[Copilot]

Adds support for MacSyFinder, a tool for detecting macromolecular systems in protein datasets using HMM-based similarity search.

Implementation

Two submodules following the tool's workflow:

• macsyfinder/download: Fetches models via macsydata

  • Input: model name (e.g., 'TXSScan', 'CasFinder')
  • Output: models directory

• macsyfinder/search: Executes system detection

  • Input: protein FASTA, models directory, optional model filter
  • Output: summary TSV, best solutions, complete results directory
  • Supports multiple database types: gembase (default), ordered_replicon, unordered

Usage

include { MACSYFINDER_DOWNLOAD } from './modules/nf-core/macsyfinder/download/main'
include { MACSYFINDER_SEARCH } from './modules/nf-core/macsyfinder/search/main'

MACSYFINDER_DOWNLOAD('TXSScan')

input_ch = Channel.of([
    [id: 'sample1', db_type: 'gembase'],
    file('proteins.faa')
])

MACSYFINDER_SEARCH(
    input_ch,
    MACSYFINDER_DOWNLOAD.out.models,
    'TXSScan'
)

Technical Details

• Container: macsyfinder:2.1.6 from biocontainers
• Both modules include complete meta.yml documentation and nf-test definitions
• Search module captures HMMER version alongside MacSyFinder

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• api.anaconda.org

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

<agent_instructions>Macsyfinder is compatible with models, they are here. We need to build models first and then run Macsyfinder, so it will be several sunmodules</agent_instructions>

@copilot , please take a look at this: https://nf-co.re/docs/tutorials/migrate_to_topics/update_modules and ensure that you use the topic channel to emit the versions, rather than creating the versions.yml

Hi @SPPearce, thanks for pointing this! I've already modified it in my local environment. Could you kindly review this PR? Btw do you know how to fix the error from linter, which tells that md5sun for empty file is found? MSF produces this empty .err files intentionally and I can't change it

[mashehu]

to fix the linting error make sure that the file is actually emtpy (with path(.out.err).text == "" please add the full channel name there).

[mashehu]

this PR is also missing snapshot files

[brovolia]

Sure, after linting my changes, I will push the snapshots here
