Re: [ccp4bb] What really happens in XDSCONV?

Dear Kay, Concerning usage of programs, everybody has his/her preferences, but what could be simpler than a 2-liner XDSCONV.INP like INPUT_FILE=XDS_ASCII.HKL OUTPUT_FILE=temp.hkl CCP4 ! or CCP4_F or CCP4_I or SHELX or CNS and then running XDSCONV by running xdsconv? At least there's not

Hi Derek I strongly recommend comparing with pointless/aimless, *not* pointless/ scala (if you have the time!) Scala is obsolete and was superseded by Aimless several years ago (I think 2010, without checking...). I find that Aimless is not only much faster than Scala, but also scales

Hi, I am a long time user of XDS (20 years this year) but all the same I find that I have constant angst about losing observations because I don't understand what goes in in the conversion steps to get to CCP4 format. I used to believe that XSCALE was always necessary, and I always use it in

Hi Tim, I would actually recommend using pointless (or xprep) instead of xdsconv. It is much easier to use and maybe even less error prone. I take the point about pointless but XPREP is commercial software sold by Bruker and costs €700 (as I remember), so is not really an option for everyone.
