I got a error when executing hdp

[dengjl]

gsl: ../gsl/gsl_rng.h:200: ERROR: invalid n, either 0 or exceeds maximum value of generator
Default GSL error handler invoked.

because one (or more) of your documents has zero length

Just for the record: even though I got a slightly different error on Windows 10 with MinGW32

gsl: ..\rng\rng.c:146: ERROR: invalid n, either 0 or exceeds maximum value of generator

The solution was also to exclude empty documents.
