Regarding msi2lmp tool

Hi Axel,
               I used the msi2lmp tool to get the data file, but I
encountered the following problems
  1.Unable to find mass for c3a
  2.Unable to find equivalent type for c4
   Also the data file formed showed the value 0 for all mass, angle_coeff,
dihedral co-eff

        Can you kindly tell me how can I resolve the following problem.
        Kindly awaiting your reply

Thanks a lot,
Parag Kanitkar

I don't use the msi2lmp tool myself, and it
is pretty old. Maybe Stephanie has some
ideas for you. I think she has worked with
the tool more recently.
