Add H atoms to alkenes

Hello,





When I add explicit H atoms to a compound that contains a less-than-tetrasubstituted alkene, one of the alkene H atoms that is added is given a squiggly bond, indicating a cis/trans mixture, even if I have specified a certain stereochemistry of the alkene in the first place. This practice is bad. I do not want the process of adding explicit H atoms to change the meaning of my drawing. Even when the alkene is monosubstituted, one of the new bonds becomes squiggly, which is completely meaningless. Please change the algorithm so that H atoms are added only with regular bonds.

Hi Bob,





You are right. We will change this behaviour.

Thanks. When will the change be available?

Hi Bob,





Hopefully in the next week I can start workin on this, so it seems that the end of the next week I'll be ready.





I will mention here, if it is ready.

It is ready. Thank you for the report.

It will be available in the next release of JChem, right? (We prefer not to download alpha or beta versions, as our students ae using the program.) Do you yet have an estimate on when the next release will be ready? (Days, weeks, ....)

Yes, JChem release will follow Marvin.


I hope we can release Marvin in a few weeks.

Could you tell me when this will be fixed, or already fixed?


Thank you.

This issue is fixed since Marvin 4.1. The next major JChem version (3.2 - coming out very soon) will also contain a fixed Marvin version.





Best regards,


Szabolcs
