Does anyone know a way to help PubChem fix/update OECHEM toolkit to
properly create cumulene 3D structures? (allene is planar). Is this just a
version issue?

Hi,

A follow up:

This is an issue with the OEChem toolkit adopted by PubChem workflow to
process chemical structures and to generate 3D coordinates. It has problems
with allenic structures. The team is exploring other toolkits, which will
take time. Another point - currently there is no existing mechanism to do
any manual update due to human resource constraint.

Your patience and understanding will be greatly appreciated!
