CMU Sphinx / Forums / Help: Problem in getting nbest list

Hi,
I am trying to get n-best list using pocketsphinx (0.6.1) with the following
configuration, but not getting it. What could be wrong with the command
-hmm I:\sphinx\pocketsphinx\model\hmm\en_US\hub4wsj_sc_8k
-dict I:\sphinx\testdata\2803.dic
-lm I:\sphinx\testdata\2803.lm
-hyp I:\sphinx\testdata\ngram.hyp
-fwdflat 1
-fwdtree 1
-adcin yes
-nbestdir I:\sphinx\testdata\nbestdir
-ctl I:\sphinx\testdata\2803.ctl
-cepext .raw
-cepdir I:\sphinx\testdata.

After typing the command : I am getting following output on the console:

INFO: cmd_ln.c(512): Parsing command line:
