$ module avail circos

Notes from the sysadmin during installation:

$ wget http://circos.ca/distribution/circos-0.69-9.tgz
$ tar zxf circos-0.69-9.tgz 
$ cd circos-0.66-9

Circos needs some Perl modules, check which we satisfy already:

$ cd bin
$ ./circos -modules

For missing modules, check and install from the system package manager first:

$ yum install perl-Clone.x86_64 perl-Config-General.noarch perl-Font-TTF.noarch perl-Readonly.noarch perl-Regexp-Common.noarch perl-Text-Format.noarch perl-Math-Round

Install any other missing modules manually using cpanm:

• Math::Bezier
• Math::VecStat
• SVG
• Set::IntSpan

Create directories for perl modules:

$ sudo mkdir -p /export/apps/circos/0.69-9/lib/perl5
$ sudo chown -R aorth /export/apps/circos/0.69-9
$ cpanm -l /export/apps/circos/0.69-9/ Math::Bezier
...

$ PERL5LIB=$PERL5LIB:/export/apps/circos/0.69-9/lib/perl5 ./circos -modules

$ cd /tmp/src/circos-0.69-9
$ cp -r * /export/apps/circos/0.69-9

Add install directory to PATH and PERL5LIB and try to run it:

$ export PATH=$PATH:/export/apps/circos/0.69-9/bin
$ export PERL5LIB=$PERL5LIB:/export/apps/circos/0.69-9/lib/perl5
$ circos -modules

$ sudo chown -R root:root /export/apps/circos/0.69-9
