A function to handle a salmon docker container

This function executes a docker that produces as output the transcripts count file generated by Salmon quasi-alignment

salmonCounts(
  group = c("sudo", "docker"),
  scratch.folder,
  fastq.folder,
  index.folder,
  threads = 8,
  seq.type = c("se", "pe"),
  strandness = c("none", "forward", "reverse")
)

Arguments

group,

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

scratch.folder,

a character string indicating the path of the scratch folder

fastq.folder,

a character string indicating the folder where input data are located and where output will be written

index.folder,

a character string indicating the folder where transcriptome index was created with salmonIndex.

threads,

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

seq.type,

a character string indicating the type of reads to be generated by the sequencer. Two options: "se" or "pe" respectively for single end and pair end sequencing. Strandness is inferred by salmon.

strandness,

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