Re^2: Gamess-US external basis set into FF format


Hi Vyacheslav,

thanks for the confirmation.  It seemed suspiciously too simple, although it appeared to work well, which is why I wanted to check it out.

>>Hello forum followers,

>>I have downloaded the 6-311++G(3df,3pd) basis set from the EMSL basis set exchange (, using the GAMESS-US format, since there is no option for FF format.  Looking inside the downloaded file, which I have named full.lib, I notice differences between the GAMESS-US format and the FF format through comparison of the contents with the cc-pVTZ.lib file, available from the FireFly downloads section.

>>By inspection, I merely removed $DATA  ...   $END from my full.lib and renamed the element to its abbreviated form, followed by 3 spaces and the word full (i.e. HYDROGEN becomes H   full, LITHIUM becomes Li   full etc).

>>I am actually using this edited form of full.lib on a run now, but I am not sure that the successful start of a run is proof that I edited the file correctly, and that FF is using the edited full.lib correctly.  I have attached here cc-pVTZ.lib (from FF download page), the un-edited full.lib (containg 6-311++G(3df,3pd) basis set) and the edited full.lib file which I am currently using.

>>If anyone could confirm I have done this correctly I would be grateful.
