For two years we have been developing a web interface to some quantum chemistry programs developed at Calvin. We're preparing a manuscript for J. Chem. Ed. describing these. The approach that we took was to keep the original FORTRAN programs intact but to develop a web-form based interface calling a CGI script that runs the progroams and prepares numerical and graphical output that is returned to the user. We also have a quantum chem primer and excerises on on-line to support these. The URL's for the forms are given below. The main URL for the site is http://www.calvin.edu/chemistry/computational/computationalTOC.html You are welcome to check these out and comment if you like. My main reason for writing, however, is not to promote the site, but rather to get some help with a problem that we are having. I recently submitted this problem to the comp.infosystems.www.authoring.cgi newsgroup, but have not received any help yet. So, since this was a chemistry based web-group, I thought I might get some help here. The CGI scripts worked under Netscape 1.12. They still work with Netscape 2.0.2 on a UNIX box (Sun and SGI). BUT they don't work with Netscape 2.x and up (even 3.0b4) on the Mac. I think that they work okay under Windows and Windows 95, but I haven't tested them extensively there. Has anybody heard of such weirdness? They are fairly complicated CGI's that take some form data and then run some computational chemistry programs on the data. Here are some of the form URL's for anyone who wants to try them out: http://www.calvin.edu/chemistry/computational/begatom/begform.html http://www.calvin.edu/chemistry/computational/atom/atomform.html http://www.calvin.edu/chemistry/computational/atomplus/atomplusform.html http://www.calvin.edu/chemistry/computational/ion/ionform.html http://www.calvin.edu/chemistry/computational/webgauss/webform.html http://www.calvin.edu/chemistry/computational/webadvgauss/webadvform.html The problem seems to be in the parsing step, which is a C program. The rest of the CGI script seems to work fine. In other words, it takes the default values from the form or old input files from a previous run and works on them. Of course, this is disastrous because the user thinks that the data returned is for the data input in the original form submission, but is not. Thanks for anyone who can help. Terry M.
