Hi Francesco, The problem is that Chimera 1.6.1 can't handle prmtop files generated by Amber 12. You need to use the current daily build of Chimera. This problem would also be fixed if we made a 1.6.2 release, but it looks like we're going to make a 1.7 release (eventually) instead. --Eric On Jun 4, 2012, at 2:54 PM, Eric Pettersen wrote:
Hi Francesco, I have seen this error reported a couple of times, but the reports were anonymous and I couldn't do much to solve the problem. Anyway, this error indicates that there are residues in the structure that have no atoms(!). Not an ideal situation. If you could send me your PSF file (or prmtop if that's what you're using) and part of your DCD, that would help me debug this. If you can't send them by mail, let me know and I'll set up FTP.
