Error with mplus2lavaan: v_post.match[1L] > 0 is not TRUE

[Jon]

From what I can tell from the comments written in around line 68 here, this error has something to do with how model constraints are specified in the Mplus syntax file, where the use of hyphens (e.g., x1-x3* instead of x1* x2* x3*) confuses lavaan. I have over 2 million Mplus syntax files that I'd rather not rewrite. Is there a way around this error? I've attached an example of my syntax. Thanks!

Sorry, forgot to give details of my system. See below, and I'm running lavaan version 0.5-18

The author of the mplus2lavaan() function is Michael Hallquist
(http://www.psychiatry.pitt.edu/node/8545)

I would contact him directly, and maybe, he may find the time to solve
this...
