I have been working on a structure for a very long while.  We have a number of data sets with the good ones mostly around the 3.1-3.2 A range.  I do have a determination of the structure but would like to see if I can get the structure determined with a slightly higher resolution data set at around 2.7 A.  Problem is the 2.7 data is twinned.  Are there settings in Phaser to handle twinned data or is the twinning only handled during refinement?  

Thank you for any advice, outside of forgetting about the twinned data.
