Hi Chen, You can set the target number of omit regions with the keyword n_box_target: n_box_target= None You can tell the Wizard how many omit boxes to try and set up (but it will not necessarily choose your number because it has to be nicely divisible into boxes that fit your asymmetric unit). A suitable number is 24. The larger the number of boxes, the better the map will be, but the longer it will take to calculate the map. The number of processors is up to you. The suggestion of 5 times the number of boxes is the maximum number of processors that would be useful. All the best, Tom T ________________________________________ From: [email protected] [[email protected]] on behalf of Qiang Chen [[email protected]] Sent: Monday, March 05, 2012 10:03 AM To: PHENIX user mailing list Subject: [phenixbb] SA-OMIT map/omit regions HI all, I want to use phenix.autobuild to calculate SA-OMIT map. BY default, it will be seperated into 16 regions. How could I set a different number of omit regions? Is there any difference of the final omit map by setting different regions? The phenix.autobuild manual says: If you are calculating an omit map, then use nproc=5 * number of omit regions (i.e., up to 100 or more, depending on how many processors you have). Does the * mean to use regions number to multiply 5? If my computer have 16 processors and I want to use 48 regions, so my command should be this: nproc=240. Am I right? Thank you!
