join outputs of two processes emitting single tuple each

[darked89]

Hello,

I have a single genome input which is then processed by two processes:

1. one (using all chromosomes)
2. two (processing just MT)

The outputs for both are tuples: bed, fasta, out files with a prefix.

The proof of concept with join and it looks like this:

nextflow.enable.dsl=2
debug=true

process one {

output:
    tuple val(my_key), val(one_bed), val(one_fa)
script:

  my_key = "t2t"
  one_bed = "1.bed"
  one_fa = "1.fa"
"""
"""
}

process two {
output:
    tuple val(my_key), val(two_bed), val(two_fa)

script:

my_key = "t2t"
two_bed = "2.bed"
two_fa = "2.fa"
"""
"""
}

workflow {
    one()
    two()
    combo_ch = one.out.join(two.out)
    combo_ch.view()
}

Question:
is there a more straightforward way achieving it?
