Subject location for hierarchy file
I want to create a hierarchy classifier. The command in the configuration file that I am using is:
        classify       Hierarchy -hfile subject.txt -metadata Subject -sort Title
Question: Where do I put the "subject.txt" file so that the build.pl file can find it? I have tried several places and haven't succeeded (I get the error "ERROR: Buildcol.pl failed")
Can you point me in the right direction?
