Hi,

I am facing a problem with opening pdb files in material studio. I am converting lammps data file to pdb format using lammps2pdb.pl and importing them in MS for surface area calculations. Most of the pdb files open without any error but a few of them display only positions of the atoms in the box and nothing about bonds and atom types. I am attaching the pdb files and screenshots of MS for both the good and erroneous cases. I glanced through the pdb files but could not find any difference between the two. Can anyone please tell me what is going wrong?
