Never having been fortunate enough to gather enough data to write a paper, I was nonetheless under the impression that there was nothing wrong in writing papers using data from your thesis.
You shouldn't, of course, re-use data in more than one paper, but given that the chances of the wider community reading your thesis are, alas, slim, I think it's permissible to rebrand the data for a wider audience. You'd have to rewrite the text, but that's good practice for adapting to another audience anyway. Certainly there seems to be no problem incorporating data from your own papers into a thesis, so I can't see why there would be an objection the other way around.
