Generate a different test set and repeat refinement. Do it twenty times. If R turns out to be systematically higher than Rfree even in few resolution shells, you have an interesting case worth looking at. If not, it's just noise.

</div>Hello everybody,
While depositing a structure in PDB, I observed that Rwork was more than Rfree in the highest resolution shell and in a few more shells as well. I shall be delighted if somebody can suggest me the reasons and also what should I do now.
