Problem: I have nextflow version 22.04.5.5708 and I am running a nextflow script using the following command:
nextflow run core_bioinfo.nf
Script:
nextflow.enable.dsl=2
workflow {
ch_infiles = Channel.fromPath(params.infiles,checkIfExists:true)
ch_api = Channel.fromPath(params.api,checkIfExists:true)
today()
mk_today(ch_infiles,today.out) | view
query_api(ch_api,today.out,ch_infiles)
}
process today {
tag "Get todays folder"
output:
stdout emit: day
script:
"""
echo \$(date +"%Y.%m.%d")
"""
}
process mk_today {
tag "Make todays folder"
input:
path seq_dir
val day
output:
stdout
script:
"""
mkdir -p ${seq_dir}/${day}
"""
}
process query_api {
input:
path api
val day
val seq_dir
output:
file("${day}.sample_source_sample_pcrs.csv")
script:
"""
python ${api} > ${seq_dir}/${day}/${day}.sample_source_sample_pcrs.csv
"""
}
Running this script is giving me the following output:

Checking /home/bkutambe/Documents/Core Bioinfo/work/d9/846551a8367ec0c0ce724e83d91edb/.command.sh reveals this:
My observation:
the problem is nextflow is splitting the command of process query_api into 3 separate lines in the .command.sh.And running as it is,is what is giving that error. How can this be solved?
