Hi, If I write a question in this way: .... QS "syl_rel_pos_in_pw==0" { *&0+*$1+* , *&0+*$2+* , *&0+*$3+* } QS "syl_rel_pos_in_pw==1" { *&1+*$3+* , *&1+*$4+* , *&2+*$4+* , *&1+*$5+* , *&2+*$5+* , *&3+*$5+* } .... One pattern of the question matches two non-neighbour symbols in the label. Will it work? Na Xingyu Beijing Institute of Technology
