DESCRIPTION

       Circos is for visualizing data in a circular layout, ideal for exploring relationships
       between objects or positions. There are other reasons why a circular layout is
       advantageous, not the least being the fact that it is attractive.

       Circos is not a solution. It's a tool to solve visualization problems. For a given
       problem, you are not guaranteed that it's appropriate.

       You have fine control over how each data element is displayed, helping you to match
       salience to pertinence.

CONFIGURATION

       Settings are meant to be passed using a plain-text configuration file. This file can be
       created manually or by another script, which allows Circos to be fully automated.

       For full documentation, see

         L<http://www.circos.ca/documentation/tutorials>

   Syntax
       Configuration is plain-text and composed of hierarchical blocks. Some blocks, such as
       "<ideogram"> are mandatory, while others like "<backgrounds"> are optional.

       To get started, refer to the quick guide tutorial.

         L<http://www.circos.ca/documentation/tutorials/quick_guide>

       A typical configuration file might look like this

         # image size and format
         <image>
          ...
         </image>

         # position and size of ideograms
         <ideogram>
          ...
         </ideogram>

         # position, type and format of data tracks
         <plots>
          <plot>
            ...
          </plot>
          ...
         </plots>

         # colors, fonts and fill patterns
         <<include etc/colors_fonts_patterns.conf>>

         # system parameters
         <<include etc/housekeeping.conf>>

   Modularity
       The "<<include FILE">> directive imports one configuration file into another. This
       facility helps to keep configuration files modular.

       Parameter definitions that do not frequently change, such as color and font definitions,
       are conventionally imported from files found in etc/ in the distribution.

       In the tutorials, you'll find that the "<ideogram"> and "<ticks"> blocks are imported into
       the main configuration file. Because these blocks can get quite large, the main
       configuration file is more legible if they are relegated to separate files.

   Overriding with *
       To override a parameter that has been included from a file, use the "*" suffix. The suffix
       is required because multiple definitions of a parameter are not allowed, except in cases
       where a parameter is may have more than one value.

         <image>
         # included file defines 'radius'
         <<include etc/image.conf>>
         # this will override the radius value
         radius* = 2500p
         </image>

       The "*" suffix can be repeated to specify which value takes precedence in a block.

         radius = 1500p
         radius* = 2500p
         radius** = 3000p # this instance of radius will be used

   Overriding with Command Line
       Any configuration parameter in a unique block name can be specified on the command line
       using

         -param PATH/PARAM=value

       For example,

         <ideogram>
           show = no
           ...
         </ideogram>

         -param ideogram/show=no

       and

         <ideogram>
           <spacing>
             default = 0.01r
           </spacing>
           ...
         </ideogram>

         -param ideogram/spacing/default=0.01r

       When conf() is used in the configuration file to retrieve the value of a parmameter (any
       parameter, not just those set by -param), you get a flexible system for changing the
       configuration at the command line.

         species = human
         karytotype = data/karyotype/karyotype.conf(species).txt

         -param species=rat

       Multiple parameters can be redefined, each with its own "-param" flag

         -param show_ticks=no -param image/radius=2000p

   Merging Blocks
       Multiple instances of the following blocks are automatically merged: "<ideogram">,
       "<colors">, "<fonts">, "<paterns">, "<image">, "<links">, "<plots"> and "<highlights">.

       The purpose of this is to allow you to add to canonical definitions.

         # this file defines default <colors>, <fonts> and <patterns>
         <<include etc/colors_fonts_patterns.conf>>

         # add to the colors block
         <colors>
         mycolor = 150,25,25
         </colors>

OPTIONS

   Configuration
       -configfile FILE
           Name of configuration file. This is required.

           Circos will attempt to guess the location of this file, searching for "circos.conf" in
           ".", "..", and "../..".

   Output Format
       -png, -nopng
       -svg, -nosvg
           Toggles output of PNG and SVG files.

   Image Elements
       -show_ticks, -noshow_ticks
       -show_tick_labels, -noshow_tick_labels
           Override the display of ticks and their labels. These are both usually defined in the
           <ticks> block.

   Output Paths
       -outputdir DIR, -dir DIR
       -outputfile FILE, -file FILE
           Change the output directory and filename. The FILE can contain a path.

   Debugging
       -debug
           Turn on basic debugging output. Reports information from

             image, io, layer, summary, timer

           debug groups (see below).

       -debug_group {+-}GROUP1,[{+-}GROUP2,...]
           Turn on debugging output for specific groups. For a list of groups, see

             L<http://www.circos.ca/documentation/tutorials/configuration/debugging>

           To add a group to the output prefix it with +. To remove it, with -.

             # use default debugging groups but exclude layer and io
             -debug -debug_group -layer,-io

             # use default debugging groups and add spacing
             -debug -debug_group +spacing

             # explicitly specify the groups
             -debug_group png,io,timer

           To list the groups that are supported, use the flag without an argument

             -debug_group

       -time
           Report timing information. Same as -debug_group +timer

       -silent
           Generate no reporting.

       -paranoid, -noparanoid
           Run in paranoid mode (default), or not. The default for this setting is defined by
           'paranoid' in etc/housekeeping.conf.

       -warnings, -nowarnings
           Display warnings, or not (default). The default for this setting is defined by
           'warnings' in etc/housekeeping.conf.

       -fakeerror =item -fakeerror CAT =item -fakeerror ,ID =item -fakeerror CAT,ID
           Fake an error by displaying the error message for category CAT and error name ID. If
           one or neither are specified, lists which errors are available.

           Unless you truly enjoy seeing error messages, there should be little reason for you to
           want to use this.

   Usage
       -version
           Show the version.

       -help
           Show brief usage synopsis.

       -man
           Show man page.

   Goofing Around
       -randomcolor [color1,color2,...]
           Randomize the color of every element in the image, except for an optional list of
           colors.

           For example, to keep the background white and anything that is black,

             -randomcolor white,black
