Your responses are tantalizing. In what way are the files not correct? As Garib says, the N+ is not chiral (and hence @ should not be needed). Paul. On 09/05/12 20:13, Shya Biswas wrote: does not give correct files needed to insert special symbol @ after N+ Shya On Wed, May 9, 2012 at 2:57

Shya, Elbow command: phenix.elbow --smiles="O=C(C[N+]23CN1CN(CN(C1)C2)C3)c45c45" will give you CIF and PDB files. I just tried, it took 5 minutes to calculate them on my mac. Pavel On Wed, May 9, 2012 at 9:08 AM, Shya Biswas wrote: > Hi all, > I am having trouble generating a pdb and

Interesting: N+ does not seem to be chiral. Three out of four carbons attached to it seem to be equivalent. Garib On 9 May 2012, at 18:13, Shya Biswas wrote: > The following seems to work with phenix: > O=C(C[N@+]23CN1CN(CN(C1)C2)C3)c45c45 > Shya > > On Wed, May 9, 2012 at 12:15 PM, Bo

Hi Paul The pdb file that you send me does not have the right geometry, have tried phenix elbow, same problem not the right geometry however in consultation with Nigel it looks like a special symbol had to be inserted in smiles, he send me a file that looks like correct. thanks to all who helped, S

multiple ways of getting there: I used Picto (OpenEye) But you can also search PubChem with your smile string and find a perfect match http://pubchem.ncbi.nlm.nih.gov/summary/summary.cgi?cid=437043&loc=ec_rcs If you look around you will find what you need on that web page. Jürgen On May 9, 2012,
