selecting atoms on the basis of their ForcefieldType?

Hello,

Is it possible to select atoms on the basis of their ForcefieldType? Similar to this:

foreach my \$atom (@\$atoms) {
my \$ffType = \$atom->ForcefieldType;
if(\$ffType == "c"){
push (@listofatoms, \$atom);
}
}

(This does not work. Maybe the "c" part is wrong?)

I know that it works for example with NumBonds or AtomicNumber. Like this:

if(\$atom->NumBonds == 42){

}
if (\$atom->AtomicNumber == 42){

}

Many thanks for your help!

Best wishes
