[Chimera-users] Add Charges failure (libquadmath)

[Lluis Blancafort]

Hi,

I’m running Chimera alpha version 1.11 on Mac OSX El Capitan 10.11.2

The Add Charges tool does not work for non-standard residues with AM1-BCC. The Reply Log reports a problem with libquadmath and later with sqm utility (see below). I don’t have libquadmath.0.dylib installed.

Can anybody help?

Thanks!
