Re: [phenixbb] Implementation of French & Wilson data correction?

Jeff, Thanks! So it sounds like if we use Mosfilm to process raw image files then Scala/Truncate prior to input into Phenix as a MTZ file we wouldn't want to employ this option in Phenix.

I'll give it a go! I know Otwinowski well and we have had many discussions about negative intensities. Do you know if Scala/Truncate resets negative intensities to 0?

Both truncate and ctruncate include an implementation of the F&W method, so negative intensities will be scaled to have a positive value.

Thanks, Jeff
