[Chimera-users] code 5 error

[Elaine Meng]

Hi Steve,
This is a common problem reflecting the numerical failure of the MSMS  
code on some fraction of structures (it is in the "Known Bugs" section  
of the release notes).  The MSMS code was developed elsewhere, and we  
are working on our own code to replace it, but it is not done yet.   
Sometimes you can avoid the numerical failure by changing something  
slightly, such as VDW radii, probe radius, and sometimes even just the  
orientation of the molecule, but it is unpredictable and different for  
every different structure as to what might work.

The most recent post, mentions recent changes we made in Chimera to  
decrease the problem severity:

I hope this helps,
