*** CIRCOS ERROR ***
CONFIGURATION FILE ERROR
Circos could not find the configuration file. To run Circos, you need to
specify this file using the -conf flag. The configuration file contains all
the parameters that define the image, including input files, image size,
formatting, etc.
If you do not use the -conf flag, Circos will attempt to look for a file
circos.conf in several reasonable places such as . etc/ ../etc
To see how configuration files work, create the example image, whose
configuration and data are found in example/. From the Circos distribution
directory,
cd example
../bin/circos -conf ./circos.conf
or use the 'run' script (UNIX only).
Configuration files are described here
http://circos.ca/tutorials/lessons/configuration/configuration_files/ and the use of command-line flags, such as -conf, is described here
