I'm confused... I just tested creating an OBMol with a PDB with ~32K atoms and it worked. I definitely remember reading discussion where Noel was mentioning a limit (that at this point can't be 1k atoms) but I can't find it since Sourceforge seems to be down for maintenance. In any case, dealin

I have used mol2 files with many thousands of atoms. Can you explain why you think there's a restriction or send me an example file? Thanks very much, -Geoff --- Prof. Geoffrey Hutchison Department of Chemistry University of Pittsburgh tel: (412) 648-0492 email: geo...@pitt.edu web: http://hutch

Hi, I had a similar issue and my recollection is that it's a hardcoded limit in OpenBabel. Not sure how feasible would be to remove or extend this limit, but in the meantime I had to find workarounds to get the job done. The best solution for me was to write a file parser to process a chain at t

2015-02-10 Thread Browning Nicholas John
Hi All, It seems to me that there is a restriction on the number of atoms (~1000) OB can handle when using mol2 file format. I know this is also true for SMILES and InChI however this doesn't make much sense for mol2. I currently do mutations/atom manipulations with large proteins with non-sta
