Dear all,

if anyone of you can help me with my problem I would greatly appreciate
your help.

Background:
A few days ago I started working with the Data Explorer to visualize
results from DNA-protein simulations. The aim is to present the 
molecular structure plus some scalar/(vector) field mapped onto some
surface, define some degree of transparency for this surface, add
a legend and text to finish up things.
The first thing I was concerned about is the display of molecular
structures, say, from so-called PDB files (crystallographic xyz
coordinates of proteins/DNA). The Data Explorer has no in-built support
for this, but I found a WWW pointer to an apparently very powerful
chemistry add-on:

ftp://ftp.tc.cornell.edu/pub/Data.Explorer/by_discipline/chemistry/
supplied by the Cornell Theory Center.

I downloaded the Linux version and tried to compile things as described
in the README. There were only "minor" difficulties to get this done:
src/dx2vrml.c:522: `ERROR_DATA_INVALID' undeclared
    (used in a function to output an error message)
I just commented this part out and got things compiled.

Next I got two runtime errors:
ERROR: MDF file: Invalid data: cannot load file 'AddBonds', 
/home/siebers/dx/CMSP_Linux/bin/AddBonds: undefined symbol:
DXSetError / module AddBonds.
This concerns 2 files: FancyRibbon.c and FancyTubes.c and is 
again about the output of an error message. I commented out
the function call DXSetError() in FancyRibbon.c and FancyTubes.c
without knowing what the function really does. Well, at least
no error message window popped up anymore when starting the
Data Explorer.


Problem:
Next I tried to start some of the example ".net" programs but
virtually nothing worked. The look of the Data Explorer had changed
and lots of "CMTS" functions had been added in some panel. I have
no idea yet how to use them but I figure that if the ".net" files
don't work a new program won't work either. By chance I got an
error message which said something like " version 2.?? stuff cannot
be used in Data Explorer version 4.x." I got this message playing
around so I don't really know how I produced it.

Is the chemistry add-on outdated and cannot be used anymore with 
the current Data Explorer version? Please, help!


System:

Any comment is greatly appreciated.
