STARANISO anisotropy & Bayesian estimation server

The STARANISO Server

Anisotropy of the Diffraction Limit
and
Bayesian Estimation of Structure Amplitudes

IMPORTANT MESSAGE

Issues (see e.g. this CCP4BB discussion thread: click "By Topic: Next" to follow the thread) were found in XDS builds 20240712, 20240723, 20241002, 20250119, 20250224, 20250320 and 20250409 (check the header of the HKL format file from XDS for the exact version used). A full analysis in chronological order is available here (autumn 2024), here, here (early 2025) and here. It is recommended that any jobs run with these versions of XDS should be rerun.

We are also recommending that going forward, the file from INTEGRATE (INTEGRATE.HKL) with the corresponding XDS.INP file be used instead of the XDS_ASCII or XSCALE outputs as formerly recommended, or one of the other options detailed on the data entry page.

NEWS

Last updated May 2025: Unless test-set (R_free) flags are already present in merged data input, they are now added automatically to the output files by default (a new checkbox disables this behaviour). This means that it's no longer necessary for the user to run UNIQUEIFY and SFTOOLS to add test-set flags as per previous advice.
