Space in manta vcf header causes bcftools norm error

Description of the bug

I now realise that this pipeline does not support manta output created by sarek, but I post this here for future releases.

This is a filename parsing / channel naming issue in the pipeline rather than a bcftools problem itself.

The process is generating this output filename:

--output HD827.HD827-manta.generatesvcandidates 1.6.0.norm.vcf.gz

Notice the space:

HD827.HD827-manta.generatesvcandidates 1.6.0.norm.vcf.gz
                                      ^

Because of that, bcftools interprets:

HD827.HD827-manta.generatesvcandidates as the output file
1.6.0.norm.vcf.gz as an input argument

So it tries to open:
1.6.0.norm.vcf.gz

Which does not exist, causing:
Failed to open file "1.6.0.norm.vcf.gz"

However, the 1.6.1 comes from the manta vcf header. It is not found in my samplesheet anywhere.

Command used and terminal output

`nextflow run nf-core/variantprioritization -r 1.0.0 -resume -profile singularity -params-file params.yaml`

System information

Nextflow 25.10.4
Local executor on a workstation.
Singularity
Ubuntu
ver 1.0.0

Start with .nextflow.log.3.txt and the NFCORE_VARIANTPRIORITIZATION:VARIANTPRIORITIZATION:INPUT_PREPROCESSING:BCFTOOLS_NORM process shown in the report. Reproduce the reported command and trace how the output filename is formed. Done means the generated filename is passed as one argument without a space and bcftools norm completes successfully.
