i should have been more specific the angle should have been 89.978. also, when i process the data i get about 25% difference in r-merge between the rhombohedral(0.088) and cubic(0.112) space group. How significant is this difference? -Todd -----Original Message----- From: [email protected] on behalf of Oganesyan, Vaheh Sent: Fri 8/10/2007 4:43 PM To: PHENIX user mailing list Subject: Re: [phenixbb] conversion from h3 to r3 with phenix apps Todd, Having some experience with R3/R32 your choice for rhombohedral lattice seems a bit confusing. Are you sure the angles are 90,90,90? This might be cubic, IMHO.

Rather than struggle further on a friday afternoon, i figured that i'd give a phenix app a try. i assume xtriage can do this, can someone point me in the correct direction? thanks in advance- Todd This email was scanned with Mcafee's Anti-Virus appliance, but this is no guarantee that no virus exists.
