Dears,

i have written a pipeline in nextflow and on the subset of the data it works well, but when i used the whole dataset strange error in publishsing the output data at the final step pops up. detail of that mentioned here:

my last process in nextflow:

process Genepy_score {
    publishDir "${params.output}/Genepy_score/Genepy2_score", mode: "copy", overwrite: true
    input:
    path("Meta_files")

    output:
    path("*")

    script:
    """
    
    source activate drop
    mkdir -p Genepy2_score
    python "${params.genepy_py}" "Meta_files" "Genepy2_score"
    """
}
