Hi all,

sorry guys, this might be a silly one, but I can't see where I'm making the mistake.

Whenever I turn on TLS refinement, I get this error message.

And, as you can see, the Log file doesn't tell me much more.

I have generated the TLS groups wit the 'TLS groups selection' tool in phenix.

Any hint?

I have no clue - that error message isn't very useful feedback, I'm afraid.  Can you send me the .eff file and the PDB file off-list?  (I don't need real data for this.)
