            FastQC - A high throughput sequence QC analysis tool

SYNOPSIS

	fastqc seqfile1 seqfile2 .. seqfileN

    fastqc [-o output dir] [--(no)extract] [-f fastq|bam|sam][-c contaminant file] seqfile1 .. seqfileN

DESCRIPTION

    FastQC reads a set of sequence files and produces from each one a quality control report consisting of a number of different modules, each one of which will help to identify a different potential type of problem in your data.
    If no files to process are specified on the command line then the program will start as an interactive graphical application.  If files are provided on the command line then the program will run with no user interaction required.  In this mode it is suitable for inclusion into a standardised analysis pipeline.
    The options for the program as as follows:
    -h --help       Print this help file and exit
    -v --version    Print the version of the program and exit
    -o --outdir     Create all output files in the specified output directory.
                    Please note that this directory must exist as the program
                    will not create it.  If this option is not set then the 
                    output file for each sequence file is created in the same
                    directory as the sequence file which was processed.
    --casava        Files come from raw casava output. Files in the same sample
                    group (differing only by the group number) will be analysed
                    as a set rather than individually. Sequences with the filter
                    flag set in the header will be excluded from the analysis.
                    Files must have the same names given to them by casava
                    (including being gzipped and ending with .gz) otherwise they
                    won't be grouped together correctly.
    --nano          Files come from nanopore sequences and are in fast5 format. In
                    this mode you can pass in directories to process and the program
                    will take in all fast5 files within those directories and produce
                    a single output file from the sequences found in all files.
    --nofilter      If running with --casava then don't remove read flagged by
                    casava as poor quality when performing the QC analysis.
    --extract       If set then the zipped output file will be uncompressed in
                    the same directory after it has been created.  By default
                    this option will be set if fastqc is run in non-interactive
                    mode.
    -j --java       Provides the full path to the java binary you want to use to
                    launch fastqc. If not supplied then java is assumed to be in
                    your path.
    --noextract     Do not uncompress the output file after creating it.  You
                    should set this option if you do not wish to uncompress
                    the output when running in non-interactive mode.
    --nogroup       Disable grouping of bases for reads >50bp. All reports will
                    show data for every base in the read.  WARNING: Using this
                    option will cause fastqc to crash and burn if you use it on
                    really long reads, and your plots may end up a ridiculous size.
                    You have been warned!
    --min_length    Sets an artificial lower limit on the length of the sequence
                    to be shown in the report.  As long as you set this to a value
                    greater or equal to your longest read length then this will be
                    the sequence length used to create your read groups.  This can
                    be useful for making directly comaparable statistics from datasets with somewhat variable read lengths.
    -f --format     Bypasses the normal sequence file format detection and
                    forces the program to use the specified format.  Valid
                    formats are bam,sam,bam_mapped,sam_mapped and fastq
    -t --threads    Specifies the number of files which can be processed
                    simultaneously.  Each thread will be allocated 250MB of
                    memory so you shouldn't run more threads than your
                    available memory will cope with, and not more than
                    6 threads on a 32 bit machine
    -c --contaminants Specifies a non-default file which contains the list of
                    contaminants to screen overrepresented sequences against.
                    The file must contain sets of named contaminants in the
                    form name[tab]sequence.  Lines prefixed with a hash will
                    be ignored.
    -a --adapters   Specifies a non-default file which contains the list of
                    adapter sequences which will be explicity searched against
                    the library. The file must contain sets of named adapters
                    in the form name[tab]sequence.  Lines prefixed with a hash
                    will be ignored.
    -l --limits     Specifies a non-default file which contains a set of criteria
                    which will be used to determine the warn/error limits for the
                    various modules.  This file can also be used to selectively 
                    remove some modules from the output all together.  The format
                    needs to mirror the default limits.txt file found in the
                    Configuration folder.
   -k --kmers       Specifies the length of Kmer to look for in the Kmer content
                    module. Specified Kmer length must be between 2 and 10. Default
                    length is 7 if not specified.
   -q --quiet       Supress all progress messages on stdout and only report errors.
   -d --dir         Selects a directory to be used for temporary files written when
                    generating report images. Defaults to system temp directory if
                    not specified.
