Hi,
OK try this, for description put "pdb files", for MIME type put
"chemical/x-pdb", for suffices put "pdb", and then select applications
and find the path to RasMac. If you can try to put "-pdb %1" after the
RasMac path (although I'll be surprised if you can do this).
Chime is ok (it was in fact developed from rasmol) but it can't
run the rasmol scripts that we will be using in the future.
Once you have configured your browser correctly, hitting on a pdb
hyperlink should fireup rasmol and load the pdb file. From the problems
you have experienced it may be that you can't do this on a Mac using
RasMac. The work round would be to download the pdb file to disk and
then run rasmac and load the pdb file manually.

For kinemage, go for MAGE_4.3.sea and see how you get on.

Quanta is reasonably easy to use and if you some help on it then I can
let you have the brief and simple notes I use to tutor our Msc molecular
modelling and bioinformatics students. I don't think quanta can be used
for chemical mime in the same way as rasmol can. If you've got access
to the SG then you could of use the SG version of Rasmol/netscape for
which the chemical mime works fine. We certainly won't be using the
advanced features that quanta provides in the course.

To use the technical list simply mail to
pps97-98-technical@mail.cryst.bbk.ac.uk instead (in fact if you have
more questions about chemical mime etc then perhaps you should switch to
this list). The technical list works in just the same way as the
general list. These are the only two lists so far we add more as and
when they are needed.

There is no real busy time for our server, I guess the problems you've
had are the heavy load on the connecting computers between yours and
ours, 9am-1pm EST means a lot of people getting into work and starting
to surf, increasing the net traffic.

Hopefully thats answered most of your questions, any more problems then
please don't hesitate to get back to us,

Cheers,
Dave H.
