Hi all, does anyone solve their structure by molecular replacement with phaser with LLG 0? Thanks lisa

Dear Lisa, It is actually reasonably common that a clear solution (large TFZ) is found in Phaser with a negative LLG. The negative LLG tells you that the model doesn't agree with the data as well as one would expect, given what you have told Phaser about the completeness of the model and its
