Scaling and Merging: Phil Evans
Phil Evans is the programmer behind Scala which is used for scaling and merging. The presentation and slides were given at the Daresbury Laboratory, UK in 2001. This presentation gives a behind the scenes look at the various inputs and outputs of Scala. I would classify this as a though introduction to scaling and merging.
The presentation runs 52 minutes in length. Another aspect which is refreshing is that Phil simply states what he knows and does not. I for one have been to too many presentations that sidestep perplexing issues and questions.
Questions addressed:
Why are intensities on different scales?
What is the real resolution of your diffraction?
Why you should collect differently for phasing and scaling?
Notes of interest:
Turn B-factor on during Scala if you believe there is a large amount of radiation damage
Rmerge and multiplicity are inversely related
-the two references mentioned relating to this point are Weiss and Diederiches
My only compliant would be that the questions are difficult to hear at times.
