HMM Modeling

I am running the following with HMM model:Step 1:echo "196 198 199 201 203 203 205 206 208 209 211 212 214 215 217 218 220 221 223 224 226 227 229 230 232 233 234 236 239 239 240 242 243 245 246" > hmm-input
Step 2:mahout baumwelch -i hmm-input -o hmm-model -nh 3 -no 250 -e .01 -m 1000
Step 3:mahout hmmpredict -m hmm-model -o hmm-predictions -l 1000
The output does NOT seems to have correct prediction values. In step 2 if i chose to have a very small -e like .0001 then i see NaNs filling the emission matrix. Kindly suggest how to get the correct output.It would also be helpful if you can explain what is epsilon and how it gets used.thanks in advance
