CMU Sphinx / Forums / Help: No bestpath when running PocketSphinx 0.7

I have been able to piece together some of the command line arguments for
running PocketSphinx 0.7 on Windows (pocketsphinx_batch.exe) recognizing from
a WAV file. However, even though the lattice shows multiple possible paths
from the end node to the starting node, the program complains that no bestpath
was found. Here are my command line arguments:

-ctl SpeechData.batch -ctlcount 2 -adcin yes -cepdir c:\Projects\Speech\Data -cepext .wav -samprate 8000 -hmm ..\pocketsphinx\model\hmm\en_US\hub4wsj_sc_8k -dict ..\pocketsphinx\model\lm\en_US\hub4.5000.dic -jsgf ..\pocketsphinx\model\lm\en_US\mil.jsgf -dictcase 1 -outlatdir . -backtrace 1

The JSGF grammar contains a single rule with the exact phrase for the single
WAV file referenced in SpeechData.batch.

Here is the complete output from running pocketsphinx_batch.exe:
