I open a molecular structure as .pdb file in Materials Studio and then export it to .car file to convert it to lammps data file along with cvff force field using msi2lmp. But in .car files the atom types are missing (xx instead of specific atom type). Do I need to set the atom types manually? or it can be done automatically but i am missing something?

*Molecular structure .pdb and .car files are attached here

-Thanks
