Ben,
Thanks for that - there were two rows where all the responses were

Subject: Re: st: Re: mrtab syntax problem
I think this is because you have rows in the table where all groups
have zero frequency. Please inspect the table produced by your first
command. If a row contains all zeros, the test for this row cannot be
performed. Unfortunately, -mrtab- breaks in this case instead of
providing an informative message or returning missing or so. I'll see
if I can fix that.
