I'm having problems with WebLab viewer (from MSI) chopping off the last 2 atoms of XYZ files. Has anyone else experienced this? I'm using version 2.01 for Win95/NT. Just increasing the atom count at the top of the file by 2 does show all the atoms. Mark Thompson ps. This problem also happens with their buckytube.xyz sample file. pps. Other than this problem, this is a terrific structure viewer for the PC!
