Hi Ishan, No, GNU parallel is not something you can use via an API. However, if you are looking forward to implement it "inherently", you should read more about parallel computing and multi threading. I have personally tried OpenMP and OpenACC with openbabel which didn't work out so well. Still i

Hey Ishan, You can use "GNU parallel" if you are using Linux/ Unix on a multi-core processor. You may have to use variables for filenames. Hope you find it helpful. Pranav -- View this message in context: http://forums.openbabel.org/Batch-minimization-of-ligands-tp4659635p4659636.html Sent

[Open Babel] Batch minimization of ligands

2016-12-24 Thread ishan
Dear All, I have prepared ligands in chemsketch, now I have to do energy minimization of the molecules before docking. I want this to be done in batch mode as there are hundreds of ligands. I have used obminimize -ff MMFF94 -sd input.mol > output.mol which does only for one molecule. Is it possib
