  USAGE: mapview  [options]  <coords file>  [UTR coords]  [CDS coords]

  DESCRIPTION:
    mapview is a utility program for displaying sequence alignments as
    provided by MUMmer, NUCmer, PROmer or Mgaps. mapview takes the output of
    show-coords and converts it to a FIG, PDF or PS file for visual analysis.
    It can also break the output into multiple files for easier viewing and
    printing.

  MANDATORY:
    coords file    The output of 'show-coords -rl[k]' or 'mgaps'

  OPTIONS:
    UTR coords      UTR coordinate file in GFF format
    CDS coords      CDS coordinate file in GFF format

    -d|maxdist      Set the maximum base-pair distance between linked matches
                    (default 50000)
    -f|format       Set the output format to 'pdf', 'ps' or 'fig'
                    (default 'fig')
    -h
    --help          Display help information and exit
    -m|mag          Set the magnification at which the figure is rendered,
                    this is an option for fig2dev which is used to generate
                    the PDF and PS files (default 1.0)
    -n|num          Set the number of output files used to partition the
                    output, this is to avoid generating files that are too
                    large to display (default 10)
    -p|prefix       Set the output file prefix
                    (default "PROMER_graph or NUCMER_graph")
    -v
    --verbose       Verbose logging of the processed files
    -V
    --version       Display the version information and exit
    -x1 coord       Set the lower coordinate bound of the display
    -x2 coord       Set the upper coordinate bound of the display
    -g|ref          If the input file is provided by 'mgaps', set the
                    reference sequence ID (as it appears in the first column
                    of the UTR/CDS coords file)
    -I              Display the name of query sequences
    -Ir             Display the name of reference genes

  ERROR in the input files ! The reference seq ID can't be found in GFF files !
      The first column in the GFF file should be the ID of the reference seq. 
      The alignments file should provide the same info in the column before the last one.
      
      Here are some example records for the GFF file:
     
      gnl|FlyBase|X	Dmel3	initial-exon	2155	2413	.	-	.	X_CG3038.1
      gnl|FlyBase|X	Dmel3	last-exon	1182	2077	.	-	.	X_CG3038.1
      ...
      The fields are :
      <seq_ID> <source> <exon type> <start> <end> <score> <strand> <frame> <gene_name>
