A function to annotate salmon output

This function executes a docker that convert the transcripts count file generated by Salmon quasi-alignment in the same format of isoforms.result, geness.result of RSEM and add the ENSEMBL GTF based annotation

salmonAnnotation(group = c("sudo", "docker"), fastq.folder, index.folder)

Arguments

group,

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

a character string indicating the folder where input data are located and where output will be written, it should contain quant.sf file generated by salmonCounts
index.folder,

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

system("wget http://130.192.119.59/public/test_R1.fastq.gz")
system("wget http://130.192.119.59/public/test_R2.fastq.gz")
