Hi Everybody,
Is there a protocol for re-scaling several sets of diffraction data against
a common reference set, either native or based on a Fcalc set computed from
a common input model. The are from a number of derivatives, are all
isomorphus, and are anomalous data . We want to compare the relative peak
heights in Fo-Fc and Anom. difference maps
Cheers
Jens

Hi Jens, Not exactly..but you can put in your native and a "derivative" in an MIR script and it will scale the derivative to your "native" and write out mir_fbar.mtz in the TEMP0/ directory (you can just stop the job as soon as it has done scaling). This will apply solve local scaling. All the best Tom T autosol { quick = True seq_file = seq.dat native { data = native.sca } deriv { data = pt.sca lambda = 1.4 atom_type = Pt } deriv { data = ki.sca lambda = 1.5 atom_type = I } } ________________________________ From: phenixbb-bounces@phenix-online.org [phenixbb-bounces@phenix-online.org] on behalf of jens j birktoft [jens.knold@gmail.com] Sent: Wednesday, April 25, 2012 9:20 AM To: PHENIX user mailing list Subject: Re: [phenixbb] Scaling of diffraction data Hi Everybody, Is there a protocol for re-scaling several sets of diffraction data against a common reference set, either native or based on a Fcalc set computed from a common input model.

Hi Jens,
There's a beta version of a program called BLEND doing the rounds that'll
do euclidian hierarchy clustering for you and scale the data I believe.
That's what you want because you don't want to scale data that isn't
sufficiently isomorphous. Try asking on CCP4bb (sorry phenix). Two of the
talks at the CCP4 study weekend 2012 highlighted euclidian clustering (one
was Wayne Hendrickson and forget who the other one was... maybe it was the
XFEL talk?).
