Re: [Rdkit-discuss] rotate a conformer around an axis?

2019-02-26 Thread Taka Seri
Hi Mchal,

TransformConformer can rotate molecule with given rotation matrix I think.

I rotate mol by using the method.
Following code rotates molecule around x, y, z axis.
https://nbviewer.jupyter.org/github/iwatobipen/playground/blob/master/rotation_mol.ipynb

Unfortunately molecule will not render on github but you can view molecule
if you run the code on your PC.
I hope this would be some of help.

Best regards,
Taka

Re: [Rdkit-discuss] Atom coordinates from PDB-file

Hi Illimar,

if you are familiar with pandas DataFrames, then I would also recommend 
BioPandas for this:

Hi Illimar,

If you need to access coordinates without creating conformer object 
do you really need to use rdkit I the first place? PDB file is column 
based format, so extracting coordinates for atoms for example with 
python is very straightforward.


Lukas


To pick certains atoms on a PDB file, I'd go for biopython's Bio.PDB ->

[Rdkit-discuss] rotate a conformer around an axis?

2019-02-26 Thread Michal Krompiec
Hello,
I'd like to check if a particular axis is a C2 symmetry axis of a
conformer. How do I rotate my conformer around an axis? (apart from
extracting the coordinates into numpy, multiplying by a rotation matrix and
updating the coordinates)
Can TransformConformer function be used for this?
Thanks,
Michal
