Good afternoon! I am a relatively new user of RDKit, and mainly the C++ API.
I am trying to save in a molfile the labels D and T for the hydrogen isotopes. Like in the following molfile: MJ230401 8 8 0 0 0 0 0 0 0 0999 V2000 -0.3572 0.4125 0.0000 C 0 0 0 0 0 0 0 0 0 0 0 0 -1.0716 0.0000 0.0000 C 0 0 0 0 0 0 0 0 0 0 0 0 -1.0716 -0.8250 0.0000 C 0 0 0 0 0 0 0 0 0 0 0 0 -0.3572 -1.2375 0.0000 C 0 0 0 0 0 0 0 0 0 0 0 0 0.3572 -0.8250 0.0000 C 0 0 0 0 0 0 0 0 0 0 0 0 0.3572 0.0000 0.0000 C 0 0 0 0 0 0 0 0 0 0 0 0 -0.3572 1.2375 0.0000 T 0 0 0 0 0 0 0 0 0 0 0 0 1.0717 0.4125 0.0000 D 0 0 0 0 0 0 0 0 0 0 0 0 3 4 2 0 0 0 0 4 5 1 0 0 0 0 5 6 2 0 0 0 0 6 1 1 0 0 0 0 1 2 2 0 0 0 0 2 3 1 0 0 0 0 6 8 1 0 0 0 0 1 7 1 0 0 0 0 M END I am trying to set directly the labels in the hydrogen atoms: atom->setProp<string>("atomLabel", "D"); or atom->setProp<string>("_displayLabel", "D"); But when the molfile is generated the labels are not transferred. It seems also that when reading a mofile including the labels, they are discarded. Many thanks in advance Santiago Fraga
