Dear Jean-Marc,

I wrote my email in an iPad, and probably attaching the image failed 
somehow.


You may save the SVG image to a file as follows; it is a plain text 
XML string:


svg_image = drawer.GetDrawingText()
with open(“ h_atoms_at_ring_jn.svg”, “w”) as hnd:
    hnd.write(svg_image)

Cheers,

How did you create file h_atoms_at_ring_jn.svg?

The execution of SVG(drawer.GetDrawingText())
returns an object of type IPython.core.display.SVG
that is nicely displayed as a chemical structure by spyder
but from which I do not know how to produce a .svg file.

Re: [Rdkit-discuss] H atoms at ring junction

Dear Paolo,

many thanks, your solution worked like a charm!

Best regards,

Jean-Marc

Dear Jean-Marc,

you may retain the original mol block wedging and avoid introducing H 
atoms as follows:

from rdkit.Chem.Draw import rdMolDraw2D
from IPython.display import SVG

I tried to experiment with the great post recently published
in the rdkit-blog about drawing options.
The Mol block hereabove has no explicit hydrogen
but the function DrawMolecule()
adds two hydrogen atoms at the ring junction :

Even though this feature can be very helpful,
is it possible to let wedges along C-C bonds
carry out the geometry information without
introducing H atoms at the ring junction?

Best,

Jean-Marc Nuzillard
