[Open Babel] Question about Conformer Search
Dear users of openbabel, I am trying to generate conformers using openbabel. After trying confab, which takes rather long for large molecules, I tried the genetic algorithm and got really nice results. However, when I was testing different scoring methods I noticed that the results I obtained from "minrmsd" and "minenergy" looked fairly similar to those obtained using "rmsd". Glancing over the source I found "minenergy" and "minrmsd" to be implemented but the respective command-line parameter ignored. Is there any particular reason for this? I am using Open Babel 2.3.90 on a Linux system. On another note: Using the conformer generation, I wanted to change the number of generations without change before convergence is considered to be reached. However, the command-line parameter "--converge #" output by "obabel -L conformer" is ignored since the programme actually looks for "--convergence #". I would suggest to change one of the two to avoid possible further confusion.

Re: [Open Babel] Two smi conversion problems
I originally used "C=0" but using "[C-]#[O+]" gives the following roundtrip for me: [C-]#[O+] -> SDF -> [C-]#[OH] Since writing the above I tried installing the latest version of Open Babel and using "C=0" now gives an error and using "[C-]#[O+]" gives the correct result. Thanks for the help with this, I think the new version has solved the problem.
