hmm, strange. how do you look at the structure? creating a svg with obabel and -osvg actually seems to repair the problem when the input is a mol2 file but not if it's a pdb file could you try this: obabel -ismi 454.smi -O 454.mol2 --gen3D -h obminimize -ff GAFF -o pdb 454.mol2 > 454-gaff.pdb

[Open Babel] distorted rings with obminimize -ff GAFF

(installation: Open Babel 2.4.0) I'm getting a distorted ring (the 5-ring) when using obminimize with -ff GAFF 454.smi OC1=CC=C(C=C1)C2=NN=C(O2)SCC#C obabel -ismi 454.smi -O 454.mol2 --gen3D -h obminimize -ff GAFF -o mol2 454.mol2 > 454-gaff.mol2 when -ff GAFF is omitted the results look ok. I
