===== PARAMETERS =====

  -1
 
   --qprof1   the first-read quality profile
  -2   --qprof2   the second-read quality profile
  -amp --amplicon amplicon sequencing simulation
  -c   --rcount   number of reads/read pairs to be generated per sequence/amplicon (not be used together with -f/--fcov)
  -d   --id       the prefix identification tag for
 
 read ID
  -ef  --errfree  indicate to generate the zero sequencing errors SAM file as well the regular one
                  NOTE: the reads in the zero-error SAM file have the same alignment positions
                  as those in the regular SAM file, but have no sequencing errors
  -f   --fcov     the fold of read coverage to be simulated or number of reads/read pairs generated for each amplicon
  -h   --help     print out usage information
  -i   --in       the filename of input DNA/RNA reference
  -ir  --insRate  the first-read insertion rate (default: 0.00009)
  -ir2 --insRate2 the second-read insertion rate (default: 0.00015)
  -dr  --delRate  the first-read deletion rate (default:  0.00011)
  -dr2 --delRate2 the second-read deletion rate (default: 0.00023)
  -l   --len      the length of reads to be simulated
  -m   --mflen    the mean size of DNA/RNA fragments for paired-end simulations
  -mp  --matepair indicate a mate-pair read simulation
  -M  --cigarM    indicate to use CIGAR 'M' instead of '=/X' for alignment match/mismatch
  -nf  --maskN    the cutoff frequency of 'N' in a window size of the read length for masking genomic regions
                  NOTE: default: '-nf 1' to mask all regions with 'N'. Use '-nf 0' to turn off masking
  -na  --noALN    do not output ALN alignment file
  -o   --out      the prefix of output filename
  -p   --paired   indicate a paired-end read simulation or to generate reads from both ends of amplicons
                  NOTE: art will automatically switch to a mate-pair simulation if the given mean fragment size >= 2000
  -q   --quiet    turn off end of run summary
  -qL  --minQ     the minimum base quality score
  -qU  --maxQ     the maxiumum base quality score
  -qs  --qShift   the amount to shift every first-read quality score by 
  -qs2 --qShift2  the amount to shift every second-read quality score by
                  NOTE: For -qs/-qs2 option, a positive number will shift up quality scores (the max is 93) 
                  that reduce substitution sequencing errors and a negative number will shift down 
                  quality scores that increase sequencing errors. If shifting scores by x, the error
                  rate will be 1/(10^(x/10)) of the default profile.
  -rs  --rndSeed  the seed for random number generator (default: system time in second)
                  NOTE: using a fixed seed to generate two identical datasets from different runs
  -s   --sdev     the standard deviation of DNA/RNA fragment size for paired-end simulations.
  -sam --samout   indicate to generate SAM alignment file
  -sp  --sepProf  indicate to use separate quality profiles for different bases (ATGC)
  -ss  --seqSys   The name of Illumina sequencing system of the built-in profile used for simulation
       NOTE: sequencing system ID names are:
            GA1 - GenomeAnalyzer I (36bp,44bp), GA2 - GenomeAnalyzer II (50bp, 75bp)
           HS10 - HiSeq 1000 (100bp),          HS20 - HiSeq 2000 (100bp),      HS25 - HiSeq 2500 (125bp, 150bp)
           HS10 - HiSeq 1000 (100bp),          HS20 - HiSeq 2000 (100bp),      HS25 - HiSeq 2500 (125bp, 150bp)
           HSXn - HiSeqX PCR free (150bp),     HSXt - HiSeqX TruSeq (150bp),   MinS - MiniSeq TruSeq (50bp)
           MSv1 - MiSeq v1 (250bp),            MSv3 - MiSeq v3 (250bp),        NS50 - NextSeq500 v2 (75bp)
===== NOTES =====

* ART by default selects a built-in quality score profile according to the read length specified for the run.

* For single-end simulation, ART requires input sequence file, outputfile prefix, read length, and read count/fold coverage.

* For paired-end simulation (except for amplicon sequencing), ART also requires the parameter values of
  the mean and standard deviation of DNA/RNA fragment lengths
