Ok. This means that I have to form the .n2t file for the CHARMM field as it is 
required by x2top. For the OPLSAA field the format was:
"C    opls_157    0.000    12.011  4    H 0.108   H 0.108   H 0.108   C 0.150C    
opls_158    0.000  12.011        4    H 0.108   H 0.108   C 0.150   C 
0.150............"
How does this become in CHARMM? Shall we keep the atom names and change the 
oplsaa into atom types like CE1, CD,.....and keep the rest fixed?


The charges will be different and perhaps the bond lengths will be different.
