"Wrong number of attributes in the string" when trying to generate Descriptor File for Random Forest..

[万代豊 <20...@gmail.com>]

Hi everyone
After my several successful trials using typical KDD ID|S data and some
others  to learn how to run Random Forest, I have encountered following
error for the different data.
Not sure of the inconsistency in the "Number of Attributes" that is pointed.
At least number of fields specified in  "-d" matches with the actual in the
CSV (15 fields) .

Please let me be advised on where to check.
