Add a new Pipeline to MACSEK

To add a new Pipeline to MACSEK you first f all have to write a nextflow pipeline. The entry files for the Pipline will be present in the same folder as the Pipline start. So the input Channel of the nextflow pipeline must search for the input files in the present directory. The results must be saved also in the present directory in a Folder called 'out/'. In the up coming example we will add a fastqc/multiqc Pipeline to MACSEK. As disribed above write a pipeline with these requirements. The fastqc/multiqc Pipleine would be look like this.

Channel.fromPath('*.fq').set{channel_fastqc_file}

process fastqc{

  publishDir 'out/', mode:'copy'
  maxForks 10 \\restriction for number of Jobs startet in Parallel on your cluster 
  cpus 4 \\if their are restrictions in Ressources on your Cluster add the CPUS and memory per Job as shown here
  memory '4 GB'
  input:
    file(fastq) from channel_fastqc_file
  output:
    file('*')
    file ('*.zip') into channel_multiqc
  script:
    """
      fastqc $fastq
    """
}

process multiqc{
  publishDir 'out/', mode:'copy'
  maxForks 10 \\restriction for number of Jobs startet in Parallel on the cluster 
  cpus 4 \\if their are restrictions in ressources on your Cluster add the CPUS and memory per Job as shown here
  memory '4 GB'
  input:
    file(fastqc_result) from  channel_multiqc
  output:
    file('*')

  script:
    """
      multiqc $fastqc_result
    """
}
