Sorry, I think my reply was not case in the attached images! I happened to have the problem to see the image but I could now see all of them. I think Tim was correct, the patterns are not the same at all. Lijun On Jul 16, 2010, at 12:23 PM, Lijun Liu wrote: Dear Hui, About the so-cal

Dear Hui, About the so-called "weird" pattern, it is not a surprise at all! You mentioned you had a long-spindle shaped crystal with large cell dimensions (208 A) and a very possible P4x2x2 SG (proved by Phil). It is very likely the longest dimension of the crystal (parallel to cell edge

Dear Hui, I am not sure what you mean by the diffraction patterns looking all the same. They don't look the same to me, although they surely don't display any lunes. The diffraction goes quite a bit beyond 3.5A, but I don't know HKL2000 well enough to explain why it refuses to integration further

rar and unrar are available for linux. Something similar to "aptitude install unrar" or "zypper -i unrar", depending on the distribution, might even be faster than repacking the archive. Tim On Fri, Jul 16, 2010 at 04:37:04PM +0200, Vellieux Frederic wrote: > Hi Hui, > > I think most of us can't d

Hi Fred You probably need to install package 'unrar-free', e.g. see: http://packages.ubuntu.com/hardy/i386/unrar-free/download . Cheers -- Ian On Fri, Jul 16, 2010 at 3:37 PM, Vellieux Frederic wrote: > Hi Hui, > > I think most of us can't do much with rar archive files. > > This is a Windows

Hi Hui, I think most of us can't do much with rar archive files. This is a Windows "thing" I believe and my Linux system tells me "Archive type not supported"... Fred. hui yang wrote: Hi all, I just collected a data set from a long-spindle-shaped crystal. The data has been scaled to P1 s
