only one chromosome is being processed from channel of 24

[complexgenome]

Hi,

I'd like to run lancet variant caller for all chromosomes I am providing through a channel.
I've two scripts: main.nf and lancet.nf

main.nf

include { lancet } from './lancet_process.nf'

workflow{

        chr=Channel.of(1..22, 'X', 'Y')    

applybqsr(gatk_markduplicates.out.sorted_bam_mark_duplicates_tumor,recalibrate_bam.out.recalib_table_tumor,gatk_markduplicates.out.sorted_bam_mark_duplicates_normal,recalibrate_bam.out.recalib_table_normal)
    
lancet(applybqsr.out.recal_bam_tumor,applybqsr.out.recal_bam_normal,applybqsr.out.recal_bai_tumor,applybqsr.out.recal_bai_normal,chr)

}

lancet.nf

process lancet {
        maxForks 3
        debug true

        input:
        tuple val(sample_id_tumor),path(bqsrbam_tumor)
        tuple val(sample_id_normal),path(bqsrbam_normal)
        tuple val(sample_id_tumor),path(bqsrbai_tumor)
        tuple val(sample_id_normal),path(bqsrbai_normal)
        val chromosome

        output:
        path "CHR${chromosome}_${sample_name}.lancet.vcf"

        script:
        sample_name=sample_id_normal.split('_normal')[0]

"""
ml lancet
echo "${chromosome}"
touch "CHR"${chromosome}"_${sample_name}.lancet.vcf"
"""

}

workflow.onComplete {
          log.info(workflow.success ? "Done lancet!" : "Oops .. something went wrong in lancet" )
 }

nextflow.config:

params {

        outdir = '/sc/arion/projects/pareks02a/sanjeev/output_pipeline_nextflow/test_tiny_datasets/'
}

process {
        withName: lancet {
        publishDir = [  
                path: "${params.outdir}/lancet/",
                mode: 'copy'
        ]
        }
}

Only one file is created. Or it prints only one chromosome.

If I hard code in a separate file, write a code block pass a chromosome channel then 24 (1-22,X, Y) are processed.

How do I fix it?
