CHARMM Development Project Forums CHARMM Community Script Archive lipid C-D order parameters using CORREL

As indicated in the error message, D is expected to be a SEGID name; that was the name I used for the lipid bilayer segment in my simulation. You must change that to the name used in your bilayer model. Most of the scripts here in the Archive will require some editing to work properly.
