[hic et nunc]

hello. i'm a newbie of srilm toolkit. 
when i used wb, kn, or  mkn smoothing methods for lm making, i realized that some of ngrams are not in lm file (albeit they exists in count file).i checked for ngrams (4-5-6 ordered) and saw that, 3 and 3+grams which have 1 count are not included in lm file. is it possible to ignore this feature in srilm? if yes, could you tell me which part of the code should be changed?
thanks.
