[Joelib-help] joelib2 running error

[figo <fi...@gm...>]

Dear all,
             Follow former email, I found the joelib2 terminate singularly,
it gives the following message:
             INFO ] joelib2.example.FeatureCalculationExample - Calculate
binary SMARTS and fingerprints...
21:18:49 [ERROR] joelib2.io.types.MDLSD                   - Can not convert
string '' to type 'int' in line:
479

joelib2.io.MoleculeIOException: Error in atom/bond definition line.

joelib2.example.FeatureCalculationExample.calculateNominalDescriptors(Unknown
Source)
        at joelib2.example.FeatureCalculationExample.main(Unknown Source)

         I think it is the error that prevent the joelib from generating
binary fingerprints, so what can I do? I just used the joelib2 binary
version, and the command is : java
joelib2.example.FeatureCalculationExample+SSKey
abc.SDF  abc.CTX
Kind regards,
figo
