Hello again,

I'll try ccp4 for Windows when I am back at home (where Windows "lives" in my case).

I have certainly tried shelxle. If I remember well what is provided is a .deb file. I used alien to convert that to a .rpm file, and installation failed because of issues I can't remember (the Linux flavour here is Alma Linux 9, not Debian).

Fred.

Hi Fred,

CCP4 distributes the shelxl binary on Linux. I've not checked yet, but perhapsĀ it is also part of CCP4 on Windows?

Cheers

    Hello and thanks for the reply.

    My input file came from my checking SHELX manuals and SHELX
    instructions on the web, and trying to modify them to suit my case.

    I tried olex2 on a Windows computer (somehow olex2 did not run on
    my Linux box, and only v1.3 was able to install on that Windows
    machine and not the latest v1.5). However, olex2 (the installation
    program) does not come with Shelx program executables, and I could
    not locate the installers for the shelx software on Windows.

    Hence I am running SHELXL in line command mode on my Linux box.

    Thank you again,

    Fred.

    Hi Fred,

    I find Olex2 and shelxle are both convenient interfaces to SHELXL
    refinement, that take care of some of the details of .ins file
    format for you. However, maybe you are stuck in the starting
    gate, depending on what is malformed in your input file. Where
    did your input files come from?

    Cheers

        Hi folks,

        I have a simple question: is there an electronic bulletin
        board for
        small-molecule crystallography? I have checked the list of
        CCP projects
        and there is no CCP-project for small molecule
        crystallography in the list.

        I am trying to run SHELXL, and it fails with the cryptic
        message "** BAD
        ATOM OR UNKNOWN INSTRUCTION **".

        The alternative for me would be of course to use software
        meant for
        macromolecular cystallography (that I know) on small molecule
        diffraction data. And using the small molecule coordinate files
        transformed to a suitable format. I don't know if this is
        feasible or
        even advised. Probably not.

        Thanks,

        Fred.
