[Chimera-users] How to detect bond cross

Hi Jiying Jia,
Findclash tests for atom-atom close contacts.  Bonds are not considered, except that the default is to ignore interactions between atoms separated by 4 or fewer bonds and between atoms in the same residue.  You can change those settings with the “bondSeparation” and “intraRes” options of findclash.  Of course, it also depends on what you use as the “overlapCutoff" and “hbondAllowance" values.

I hope this helps,
Elaine
