CCL:G: .chk to .fchk



Dear All,

  I am doing AIM calculation using AIMALL and generation of .wfn file using "# MP2(full)/aug-cc-pvtz OUTPUT=WFN DENSITY=CURRENT POP=NOAB FORCE NOSYMM" route section by G03/G09 both. Now problem occurs when i run this .wfn with AIMALL (AIMQB) having an error message "Invalid traditional wfn file ! Normalisationhaek fail. Could be due to orientation inconsistency."
I have .chk file of all the system. How can i create .fchk from this .chk file? This .fchk file will generate .wfn/.wfx file with right orientation by using AIMQB (as mentioned by Todd A. Keith). So my main problem is "How can i create .fchk from this .chk file? ". OR any valuable suggetion from your side ??

Thanking a lot.

Happy New year 2011
