CCL:G: IRC & TS CALCULATION

 Dear Tarig,
 
as surely you must be in the situation of having lost the manual, waiting for a replacement from Gaussian Inc., have a look at the web page that the Gaussian people have kindly included in the web, to help in such cases. (http://www.gaussian.com/g_ur/g03mantop.htm)
 
I am sorry but personally I try to avoid propietary software because of these inconvenient situations since some time ago, but perhaps some other people can help you sending you example scripts to fix your problem. I wish you luck

 I would suggest you make sure you have a legal copy of the software, which
 should include a copy of the user's manual, and then read the manual.  Then,
 if you still can't get the calculation to work, come back to the list.
 Also, NEVER depend on 3rd party programs to generate completely accurate
 input files for Gaussian, GAMESS or any other program.  3rd party programs
 ALWAYS have limitations on what and how options they will specify .
 Jim

 Dear Sir/Mme:
 
I am a gradute student from Sudan ,working on theoretical studies of Diels_Alder reaction using G03,(following the reaction using density function theory)..my problem is that; whenever i make my (input)file by Molder and (export )it to G03 to process calculations,especially when i use IRC or TS as keywords a message pop up to me reading(insert the force constant calculations) but when i respond to this by writing(calc FC ) as key word with IRC or TS, another message pop up reading (input error)..What do you suggest i should do to overcome this?...Also is there any software that can prepare the coordinates as Z matrix?....
     Thank You so much
