If you change it in the def.site file, when you start HKL2000 and select the detector type, it has to be the one with the name of the directory of the def.site file that you corrected. If it doesn't have the values that you entered into the def.site file then you are either not choosing the correct one or it is not saving what you updated. Unless the permissions are set for a normal user or you are using the root account, you may not be able to save the values that you changed. what happens if you start HKL2000 then click on the site configuration heading? it should pop up the s.c. window. change the values then just click close. the values should be set. i would uncheck the refine buttons for x beam and y beam to see if it stays at these values. what do you see? if it goes far from these values in the refinement step, then there could be other problems. Where did you get the beam center values. if it was from a different program, then the convention for x and y may be different. some programs rotate the image. so they are not interchangeable.
lastly if you change the values in the s.c. window, unless you have the permissions set correctly, it's unlikely that you can save the values. so everytime you restart, you will have to change the values again. -Todd ________________________________ From: CCP4 bulletin board [CCP4BB@JISCMAIL.AC.UK] on behalf of Niu Tou [niutou2...@gmail.com] Sent: Thursday, January 17, 2013 3:19 PM To: CCP4BB@JISCMAIL.AC.UK Subject: [ccp4bb] HKL2000 24IDE beam center. Hi colleagues, We have collected several datasets at APS with detector 24IDE, while processing date, the beam center is obviously not in position. But no matter what values we set in "Site Configuration" or "def.site", it remains about (156, 165). Based on the image, the estimated correct center should be around (156, 157). Does anyone know how to solve this problem? Thanks Niu
