[sharp-discuss] plot SHARP electron-density map interface problem

Are you running the httpd as user 'chernhoe'? Otherwise you might need
to change the permissions to 0775 or 0777.

It is not a problem of the cgi-bin script but rather of the interface
between the browser you use and the mime-type system we have
implemented. Please note that all the viewing capability (plots, maps,
PDB, Postscript and MTZ files) is only supported using Netscape
browser! And at least RH8 doesn't come with netscape anymore. Please
fetch a netscape binary/rpm from a previous RH version or from the
Netscape site directly. This should then work.

The things that won't work on non-Netscape browsers are:

  1. the SHARP Input file editor (started when pressing the

       'Start' SHARP based on ...

     button from the Control Panel.

  2. the viewing of maps and plots (since the mime-type system of
     Mozilla doesn't know about the various additional mime-types and
     how to handle these). 

Everything else (i.e. looking at logfiles and running autoSHARP)
should/will work for non-Netscape browsers.

PS: I can hear 'Mozilla' as a browser option - anything else?

Cheers

Clemens
