Re^2: Is the problem with internal coordinates specified by IZMAT(1)=I,... ,where I>3, fixed in FF8.2.0?

Dear Alex,

Thanks for your response. So, if I want to use/freeze a coordinate of type 6,
then I cannot use DLCs and should switch to some other internal coordinates.
Is that right?

Best regards,
Evgeniy

(dihedral angle between two planes, which is set up by four numbers). I am asking because there was some problem with those coordinates in the previous version(s).
