If you have an SGI then you can import a screen snapshot of your
rendered molecule into the program called SHOWCASE 9which works
like MacDraw... kind of) and then save it as a postscript file.
This a a very nice way to add text, titles,a nnotations etc...

But you can also use thje program "topict" to transform your .rgb
snapshot file into a PICT file and transfer it to your Mac [you
have to give it a FILE TYPE OF PICT and a CREATOR TYPE OF ???? or ttxt.
This file HAS to be transfered as BINARY and NOT MacBinary when'
you transfer it. Your FTP protocol program on the MAc may even
have an automamted way to put the creator/type automatically
upoin trnasfer...

ALternatively you can open the file from Photoshop with OPEN AS....
and choose PICT file, NOT PICT resourse!

The SGI has also a postsscript previewer so you can open and see
exactly what the printer will print before you actually do print!

It is my advice that you go to postscript only when you are done
with you output! Form the Mac you can save the postscripr file that
would have been printed. From Canvas it is Print SPecial.... and from
most other application you select PRINT... and from the Dialog box
you select the Postscript file as the output rather than the printer.


Be aware that a postscript file  containing the description of a 
color image IS usually very large. One reason to keep working from within
your e.g. Mac Draw application and keep the original. THe postscript
intermediate should only be for sending to the illustration departement
and then discarded.

I have just posted an article about MacInPlot that lets you create
CPK rendering on the Mac.

Have Fun with your SGI  and Macs, the most user-friendly computing
you can think of (well to my humble experience!),


Sincerely,
