Very nice! The picture in the thread above didn't come through for me. I
re-ran that code and got the following output, included as both an inline
PNG and an attached SVG so hopefully it shows up for folks in at least one:

[Rdkit-discuss] ConstruQt - Library-scale Quantum Mechanics SaaS

2023-06-07 Thread Peter Jarowski

Dear RDKit Community:

We will be holding a webinar to introduce our frontend SaaS for quantum
mechanics called *ConstruQt*
.
As RDKit is an essential element under the hood supporting initial guess
structures, we thought this forum would be interested to know.

Please sign-up here

.

We hope to see you there. We would also be delighted to set up individual
meetings to show what ConstruQt can do for you and your team by contacting
 us.

Best regards,
Peter Jarowski, PhD
Co-founder and Director
The ChemAlive Team
i...@chemalive.com

ChemAlive

 is leading in innovative digital chemistry solutions with focus on physics
based predictive analytics and the development of new software tools to
drive chemical discovery.
