Hi there! Thank you for developing the pipeline, I wanted to report that the pipeline fails to pull a image when using singularity profile

Jan-29 09:33:17.490 [Actor Thread 7262] DEBUG nextflow.Session - Session aborted -- Cause: java.lang.IllegalStateException: Failed to pull singularity image

The image

pygtfk:1.6.2

exist though on the depot, and manually changing the docker protocol into http allows it to pull the image and fixes the problem. I'm fairly new to using nf-core, so I'm not sure if this is an intended behavior or not. script used to submit job:

#!/bin/bash 
#PBS -l select=1:ncpus=16:mem=123gb
#PBS -N nfcircrna 
#PBS -l walltime=11:59:00 
#PBS -M sxxxxxxxx
#PBS -m ae 
#PBS -j oe 
module load nextflow/24.04.4
module load java/21.0.3_9-openjdk
nextflow run nf-core/circrna -r dev --input samplesheet.csv --outdir /srv/scratch/z5628486/Analysis/Results  --phenotype phenotype.csv --fasta GRCh38.primary_assembly.genome.fa --gtf gencode.v47.annotation.gtf -profile singularity --tools circexplorer2,ciriquant -c /scratch/Analysis/resourcelimits.config -resume -with-report /scratch/run_1.html

@Nico Trummer any idea about why this particular container is missing?

Fixed it, I missed an

https://

prefix in the singularity image URL

good catch
