    Problem with Bowtie 2

    Hi, I am a student and I'm doing work with data obtained by ChiPSeq. I am trying to do the alignment of the reads with the reference genome, but I get the following error:

    system("./bowtie2-build ./data/tair10.fasta ./data/tair10.fasta") # Indexes reference genome

    ./bowtie2-build: 20: ./bowtie2-build:

    ./bowtie2-build: 31: ./bowtie2-build: Syntax error: "(" unexpected

    Then, I attempt to put in place the following commands and I get this error:

    > resources <- list(walltime="1:00:00", ntasks=1, ncpus=cores(args), memory="10G")
    > reg <- clusterRun(args, conffile=".BatchJobs.R", template="slurm.tmpl", Njobs=18, runid="01",
    + resourceList=resources)

    Creating dir: /home/usuario/chipseq/results/submitargs01_BJdb_7642
    Saving registry: /home/usuario/chipseq/results/submitargs01_BJdb_7642/registry.RData
    Adding 18 jobs to DB.
    Error in system2(command = command, args = args, stdout = stdout, stderr = stderr, :
    error in running command
    Además: There were 40 warnings (use warnings() to see them)

    > waitForJobs(reg)
    Error in checkRegistry(reg, writeable = FALSE) :
    objeto 'reg' no encontrado

    I don't know where can be the problem. I'm using the tutarial of the following web http://girke.bioinformatics.ucr.edu/...hIPseq_04.html
    for ChIPSeq Analysys. I am working on RStudio with the package systemPipeR

    Quality Control Essentials for Next-Generation Sequencing Workflows
    by seqadmin




    Like all molecular biology applications, next-generation sequencing (NGS) workflows require diligent quality control (QC) measures to ensure accurate and reproducible results. Proper QC begins at nucleic acid extraction and continues all the way through to data analysis. This article outlines the key QC steps in an NGS workflow, along with the commonly used tools and techniques.

    Nucleic Acid Quality Control
    Preparing for NGS starts with isolating the...
