linkage symbol and compound marker

[Yuriko Oshima-Takane]

Dear Brian,

 

Could you please let me know how the linkage symbol " _"  is different from

the compound marker "+"?  I am presently teaching  the CHAT transcription
and CLAN

programs in my course and have tried to run MLU (on main tier) and MAXWD on
the 

same transcripts with the linkage symbol (Baby_Allison) or with the compound
marker

(Baby+Allison) to understand the difference between the two symbols. 

Baby_Allison/Baby+Allison occurs 6 times in the test transcripts (please see
attached).

I got slightly different MLUs as well as MAXWD output (see below). For the
MAXWD, the linkage 

symbol"_" is counted as one letter. What about MLU counts? I thought both
cases are 

counted as one morpheme word but apparently not. Please let me know why.

Thanks.
