Hello dear nf-core community ! I would like some help and suggestions on why the TEST of nf-core/rnasplice would give this error on clustering from SUPPA-module:

task: name=NFCORE_RNASPLICE:RNASPLICE:SUPPA_SALMON:CLUSTEREVENTS_IOE (YRI-GBR); work-dir=/shared/ifbstor1/projects/EPIS_SAV/NF_Core_rnasplice/work/b4/c14bf30ed590b999d1bbc709db90b3

From the .nextflow.log we can read:

-[nf-core/rnasplice] Pipeline completed with errors-

ERROR ~ Error executing process > 'NFCORE_RNASPLICE:RNASPLICE:SUPPA_SALMON:CLUSTEREVENTS_IOE (GBR-YRI)'

Command output:

Number of clustered events: 0/6 (0.000000%)

Impossible to calculate silhouette score. Only 1 cluster group identified.

The command I run is :

nextflow run nf-core/rnasplice -r 1.0.4 -profile test,ifb_core --outdir ${out_dir}

That's an already reported issue. I tried to push a PR to fix the problem, but apparently the current code is not compatible with nextflow 26, so the Github CIs fail. That would require a massive refactor of the workflow code as it heavily uses deprecated syntax. I can work on that but I'd like first to check with the maintainers.
