Running bowtie2

This function executes the docker container bowtie2

bowtie2(
  group = c("sudo", "docker"),
  fastq.folder = getwd(),
  scratch.folder = "/data/scratch",
  genome.folder,
  seq.type = c("se", "pe"),
  strandness = c("none", "forward", "reverse"),
  threads = 1
)

Arguments

group,

a character string. Two options: "sudo" or "docker", depending to which group the user belongs

fastq.folder,

a character string indicating where gzip fastq files are located

scratch.folder,

a character string indicating the scratch folder where docker container will be mounted

genome.folder,

a character string indicating the folder where the indexed reference genome for STAR is located. IMPORTANT the present function only suport genomic indexes made using ensembl genom and the corresponding gtf

seq.type,

a character string indicating the type of reads to be trimmed. Two options: "se" or "pe" respectively for single end and pair end sequencing

strandness,

a character string indicating the type ofsequencing protocol used for the analysis. Three options: "none", "forward", "reverse" respectively for non strand selection, forward for Illumina strandness protocols, reverse for ACCESS Illumina protocol

threads,

a number indicating the number of cores to be used from the application

Value

sorted.bam, sorted.bam.bai
