Fail to run other dataset

I store the yelp data(train.tsv, test.tsv, validation.tsv, test_user.tsv) at /Users/yobichi/Downloads/code_RecSys13/ so I set the
$dataloc = "/Users/yobichi/Downloads/code_RecSys13" at run.pl
and then I run "/Users/yobichi/Downloads/hgaprec-master/scripts/run.pl -dataset yelp_data -hier " in command.
There was an tricky error: cannot open file /Users/yobichi/Downloads/hgaprec-master/example/netflix.

What should I do? Thank you very much.
