Lock out ring fusion

Hello,

Is there a way to lock out fused rings using MarvinSketch? SciFinder has a Lock Out Rings tool so I'm hoping there's a similar feature.

Hi,

Sorry for the late reply. I recommend to use the rb* atomic query property. It is not exactly the same, but may work for your goals:

You can set it using the rb+ or rb- tools on the Advanced tab of the periodicSystem dialog (http://www.chemaxon.com/marvin/help/sketch/gui/dialogs.html#advanced ).

Best regards,
