Hi,

Thank you for reporting this. There is indeed an issue with a null pointer exception when no output is specified. In order to avoid this, either use the -protobuf or -db option (see http://siis.cse.psu.edu/ic3/installation.html for how to use these options). This should be fixed for the next version.

Thanks,
Damien

Hey Damien @docteau ,
Thanks for the reply. That worked !
I was wondering if there is a documentation or an example analysis on how to interpret the result which I got in the database.
Excuse me for the naivety.

Thanks,
Arnav

Hi,

For cc.properties, please follow the template from https://github.com/siis/ic3/blob/master/src/main/resources/db/cc.properties.template. You need to specify your MySQL user name and password. Note that the user you specify should have the proper permissions to perform SELECT and INSERT queries.

Regards,
Damien
