In the Phenix reflection file editor, where you pick the R-free set, there are two boxes where you can enter the fraction of reflections to go into the test set (see below), but they don't seem to talk to each other. Change the one in the "More options" sub-menu and the other stays the same with apparently no effect on the calculations. https://www.ucl.ac.uk/~rmhajc0/phenixrfree.jpg
Also, even if you tick the "Adjust test set size to specified fraction" option, it won't allow you to have more than 2000 reflections in your test set (2020 tops) i.e. there seems to be no way of overriding the "max_free = 2000" command with the gui. Probably this is very sensible and I assume it is intended? ######################################################################## To unsubscribe from the CCP4BB list, click the following link: https://www.jiscmail.ac.uk/cgi-bin/webadmin?SUBED1=CCP4BB&A=1
