Johan,

Another question - 

when i run nopt  i get a message "no decrease direction found". what
does this mean? and does it mean i have a problem?

also me results from noptest are
 # of its.: 40; % correct= 95.97
label    1    2
----- ---- ----
   1:    0  212
   2:    0 5044

do you know what my problem is? i used lpc as my signal processor and
i averaged the results in each frame and scaled them from -1 to 1.

thanks
karen
