ProCKSI

= External Software for ProCKSI = 

(needs to be updated)

Generate the following directories on each compute node to contain important executables:

{{{

/usr/local/procksi/Cluster/

/usr/local/procksi/DaliLite

/usr/local/procksi/MaxCMO

/usr/local/procksi/MolScript

}}}

For the following installation of the ProCKSI server components, the following executables must be present:

{{{

/usr/local/procksi/Cluster/qclust

/usr/local/procksi/DaliLite/DaliLite

/usr/local/procksi/MaxCMO/ProtCompVNS

/usr/local/procksi/molauto

/usr/local/procksi/molscript

}}}

== Image Software ==

=== Installation ===

   * Install ''!ImageMagick'' from [http://www.imagemagick.org www.imagemagick.org] if not already installed.

   * Install ''!MolScript'' from [http://www.avatar.se/molscript www.avatar.se/molscript]. Please link the MesaGL libraries instead of the OpenGL libraries; a modified makefile can be found under [source:ProCKSI/install/Makefile.molscript]

=== Virtual Display  ===

!MolScript needs an X display in order to generate images (jpg, gif, …). Its possible to use the console X display for the OpenGL bits even if it is not logged in. Therefore, ''procksi'' must be authenticated and allowed to use this X display virtually.

Get and unpack the ProCKSI x-authentication patch from [repos:Externals/Cluster/xauth.tgz].

On each node copy magic cookie file for x-authentication:

{{{

cp :0.Xauth /var/gdm/:0.Xauth

}}}

On each node copy scripts for automatic x-authentication:

{{{

cp procksixauth /usr/local/sbin/procksixauth

cp :0 /etc/gdm/Init/:0

}}}

Restart the X display manager for the changes to take effect:

{{{

/usr/sbin/gdm-restart

}}}

The virtual X display can be used with unix socket '':0'', e.g.:

{{{

molauto protein.pdb | DISPLAY=unix:0.0 molscript -jpeg -out protein.jpeg

}}}
