Is the "COORD=ZMT" and using z-matrix format in $DATA group necessary for the DLC optimization or not ? when I use external basis sets and ECPs (Method 1 ,http://classic.chem.msu.su/gran/gamess/index.htmlhttp://classic.chem.msu.su/gran/gamess/index.htmlhttp://classic.chem.msu.su/gran/gamess/index.htmlhttp://classic.chem.msu.su/gran/gamess/index.html), it is clear that there is not a $BASIS group in my input file, and if I use "COORD=ZMT" Firefly says :  
ERROR! USE OF COORD=CART/ZMT/ZMTMPC REQUIRES
THAT YOU SPECIFY THE BASIS SET WITH $BASIS!

I appreciate you help in advance.
