I'm a layman, but I'd like to know to to use GAMESS for some specific tasks I have Avogadro and GAMESS. I modeled the sulfuric acid molecule using Avogadro, then I asked it to generate an input for GAMMES to calculate the transitional state (I'm hoping this will get me somehow closer to my computational modeling of real chemistry). But GAMESS says the job finished with an error, and I don't know why.



It's worth noticing Avogadro seems to spell one of the commands wrong, and I have to manually correct it. Avogadro issues the command \$STATTP but GAMESS does not recognize this command, so I change it to \$STSTEP, and it ends with an error, and I try the other keyword possible \$STPT and I also get an error. Here's my 2 inputs and outputs:

This is what happens when I do what you told me, @Mitradip Das:

For GAMESS, the command is not $\$STATTP$, but it is $\$STATPT$. Also, please change the commas to dot, otherwise it considers it to be a part of the number.

Please refer to the GAMESS manual for better understanding. The link is: www.msg.ameslab.gov/gamess/GAMESS_Manual/input.pdf
