Can you give me a few more details? Does it work with the -server option? Can 
you report the actual command you are using? 

Thanks,

Adam

No more details. I tried to download both of the stated versions and generate 
ngrams for raw text file using your example, but it didn't work.

The command is:

java -ea -mx1000m -cp ../src edu.berkeley.nlp.lm.io.MakeKneserNeyArpaFromText 5 
kneserNeyFromText.arpa ../test/edu/berkeley/nlp/lm/io/big_test.txt

Please let me know if you need more info.

Does it work with the -server option? And did you first run the build script?

I'll have a chance to test things out soon, but am away from my home computer 
right now.

No it doesn't and I didn't run the build script. Do I have too?

The code I downloaded already has the JAR files and no need to re-build the src.

Yes, that script does assume you've run the build. You could change the 
classpath (-cp) to point to the jar instead of the src directory. (The src 
directory would contain the compiled .class files if you ran the script).

Sorry for the confusion,

Adam
