Null Pointer Exception when running name

Hello

I get a Null pointer exception when running name on the attached SD file using version 5.3.1

C:\Program Files\ChemAxon\MarvinBeans\bin>cxcalc name ELN.sdf
Exception in thread "main" java.lang.NullPointerException
        at chemaxon.marvin.plugin.CalculatorPluginOutput.getHeader(Unknown Source)
        at chemaxon.marvin.Calculator.initOutput(Unknown Source)
        at chemaxon.marvin.Calculator.consume(Unknown Source)
        at chemaxon.marvin.Calculator.run(Unknown Source)
        at chemaxon.marvin.Calculator.run(Unknown Source)
        at chemaxon.marvin.Calculator.main(Unknown Source)
C:\Program Files\ChemAxon\MarvinBeans\bin> 

However, when I open the same SD file in Marvin Sketch, I can successfully name the same compounds.

Thanks for your help

Hi Catherine,

I cannot reproduce the error.

C:\mols>cxcalc name ELN.sdf
id      Preferred IUPAC Name
1       methanesulfonyl chloride
2       propane-2-sulfonyl chloride
3       cyclopropanesulfonyl chloride
4       cyclopentanesulfonyl chloride
5       phenylmethanesulfonyl chloride

Please provide more details about your operating system and Java version.
Do you have a calc.properties file in C:\Program Files\ChemAxon\MarvinBeans\plugins folder?

Does this work for you?

C:\mols>cxcalc name -t preferred ELN.sdf
id      Preferred IUPAC Name
1       methanesulfonyl chloride
2       propane-2-sulfonyl chloride
3       cyclopropanesulfonyl chloride
4       cyclopentanesulfonyl chloride
5       phenylmethanesulfonyl chloride

Hello

No, the files present in the plugins folder are

calc.properties.sample.txt

extensions.jar

and plugin.properties.sample.txt

Can I rename the calc.properties.sample.txt to calc.properties ? Or should I re-install MarvinBeans ?

Thanks

Catherine

 

Hi,

No, do not rename the calc.properties.sample.txt file.

Please provide more details about your operating system and Java version, to help us reproduce the error.

We haven't managed to reproduce the error yet, but we included a fix - based on stack trace information - in Marvin 5.3.2 version. Marvin 5.3.2 will be available in few days, please test it and inform us if the error was fixed.
