[Chimera-users] problem with opening pdb-files

Hello! When I download my pdb-files from the PDB homepage and open it in Chimera (File type all (guess type) or PDB) the structure appears in a normal way first. But after a few seconds or when I start working with the molecule, the structure breaks up and there are just orderless bars and lines. Perhaps you can help me with this problem? Thank you in advance. Greetings, Bianca Ackermann Institut für Mikrobiologie und Weinforschung AG Unden Becherweg 15 D - 55099 Mainz Tel.: +49-6131-3923553
