need screen running and /usr/bin/Xvfb :55
where is screen? /usr/bin/screen
whay is SCREEN on toast?
Where is the start script for pathway on toast?
# pathway is installed in /usr/local

# these are the files inside /usr/local  copied from toast

exe        install  logfiles  pathway-tools
you need /usr/bin/Xvfb :55 
and
/usr/bin/SCREEN

when installed run /usr/local/pathway-tools/pathway-tools

I received errors:
bash-3.2# ./pathway-tools

added yum install xorg-x11-deprecated-libs !!! that worked perfectly####
Ran the /usr/local/pathway-tools/pathway-tools and a gui came up!
http://pathway-dev.stanford.edu
http://pathway.stanford.edu
to run the two different pathway applications, one is the desktop and one is the browser.
pathway has it's own browser so no apache necessary.

There was an error on the socket connection. the two programs could not talk.
We did a lot of trial and errors for this and found that all we had to do was
add the -lisp and the -api to the end of the startup command in /etc/init.d/pathway
and that worked!!!

there is no need in the 8 and above versions to start or run a server-socket.lisp for this. None whatsoever!

here is the test code to see if it is working:
perl -Mperlcyc -e '$c=perlcyc->new("yeast");@a=$c->all_pathways("")'

no errors then it works. it might fail and say connection error line 31.
Then that means the lisp and api are not running.

this is how it looks with the -lisp and -api flags
