Question about converting SALT files to CHAT format

[Ying Lu]

Dear Leonid,


Thank you very much for your reply!

For problem (a), I understand the errors are due to the unrecognized
initial characters of the tiers (e.g., $, C). But I don't know why that
happened. I suspect there is a compatibility issue here, i.e., SALTIN can't
recognize some symbols generated by the SALT 2012 student version. I will
try other SALT versions later and see if that works.

As for problem (b), I got a reply from Dr. MacWhinney last night and was
able to get the comparable MLU. Thanks a lot again for directing me to use
POST!!!

Sincerely,
Ying Lu
