Hello Hashim and other future GSoC candidates, I am a former GSoC student. I worked on the 3D structure generation of Open Babel in GSoC 2018 and 2019. https://summerofcode.withgoogle.com/archive/2018/projects/5957928301363200/

[OpenBabel-Devel] Stereochemistry check using InChIKey

2019-06-21 Thread Naruki Yoshikawa
Hi all, I've been developing a new distance geometry method these days. https://github.com/openbabel/openbabel/pull/1875 I generated SMILES from experimental structures and predict a 3D structure from the SMILES. I compare InChIKey of experimental structure and predicted structure to evaluate

s expected to be faster than current RDKit and more accurate in stereochemistry than current Open Babel. Implementing a better prediction method could be beneficial for a wide range of applications such as drug design. Thanks, Naruki --- Naruki Yoshikawa Department of Computational Biology and Medica

[OpenBabel-Devel] Getting corresponding bonds and angles from two molecules

2018-10-14 Thread Naruki Yoshikawa
Hi everyone, I'm evaluating my fragment-based coordinate generation method. I want to measure the error of bond lengths and angles, but I have a problem in getting corresponding ones from two molecules. What I want to do is like this: // mol1: ground truth loaded from SDF // mol2:

Hi Noel, I updated the fragmentation code. My code is available at https://github.com/n-yoshikawa/contributed/blob/ master/c%2B%2B/fragments/obfragment.cpp I enumerated ten most frequent fragments from our data by using this code. The result was as follows: SMILES percent [C]1=CC=[C]C=C1
