I’m going through again and can confirm that I’m copying the right files to scratch. After running the regression tests I can load the grammar in regression\_tests/grammars/ into the lkb and parse all of the sentences, but I still have 0 left results and 0 right results in the MRS compare in logs/.

One thing I notice is that all of these regression tests that aren’t “working” (that is, if I break something in my code they still succeed" have “post-reduction lexical gap” on each line in home/gold/mytest/parse. for example:

10@1@10@-1@0@-1@0@0@-1@0@0@-1@0@-1@-1@-1@-1@-1@-1@-1@-1@-1@-1@0@0@0@0@0@-1@-1@-1@-1@34728@-1@-1@-1@23-6-2013 14:28:24@post-reduction lexical gap@

Does anyone know what that means?
