Janet,

	MLU and most other commands work on word by word bases, so the -s"L2|*" or -s"*@s* options will only exclude those words, but not the whole utterance. KWAL and COMBO allow selection or exclusion of the whole utterances based on words on those utterances. If you have "[- eng]" pre-code and @s symbols on words and you want to exclude all utterances with "[- eng]" pre-code or if the utterance has at least one word with @s, then you need to use KWAL to extract the utterances you want first and then run MLU on the output of KWAL command. This KWAL and MLU commands should do what you want:

kwal -s"[- eng]" -s*@s* +o at ID +o% -d +f  filename(s).cha
mlu *.kwal.cex

If this doesn't do what you want, then please email to me a sample of your data files, so that I could see how you have coded them and give me more details on what you want to achieve.


Leonid.
