persistent error regarding smiles

Hello! I have been attempting to use jklustor on some ligands from rcsb's ligand expo, and keep getting back to this error.

 

Some features of the molecule which simplest SMILES representation is: [H][#8]-[#6](=O)C([H])([H])[#7]-1-[#6](=O)\[#6](\\[#7]=[#6]-1[C@@]([H])([#7;A]([H])[H])C([H])([H])[#8][H])=[#6](/[H])-c1c([H])[nH1]([H])c2c([H])c([H])c([H])c([H])c12 cannot be converted to smiles. Use the smarts or cxsmarts format.

 

This smile does not exist in my set!

I am running jkustor as follows:

jklustor -c mmds:5  Components-smiles-stereo-oe-edited.smi

 

I have also tried two work arounds:

1st) generating PF files with generatemd (no errors)

jklustor -c mmds:5  ligandexpo.pf

returns nothing,

2nd) standardize or molconvert to .sdf

same error

System Info:

Ubuntu 14.04

JKlustor - clustering command line frontend v0.07 

 

EDIT: converting to cxsmarts works without concern, but  jklustor -c mmds:5  ligands.cxsmarts still returns the same error

converted to sdf then tried again -> brought out the error message i needed:

"Molecule  has not supported feature at atom 3: atom has radical which would be lost.

Use the cxsmiles, smarts or cxsmarts format."

 

note that this did NOT show up when running jklustor on the original .smi file

using standardize fixed the problem.
