Tojatilar Reflection Conditions along screw axes. You also need enough data for the analysis of systematic absences. Which one should I choose? What are the three Scalepack output Files? The refined parameters are visible in the upper right portion of the screen. But if you particularly want to fix mosaicity during integration e.

As k,B are expected to be smoothly varying they are often restrained during scaling. The goniostat has no vertical hkkl on the phi axis, but there is a certain amount of vertical travel on the goniometer head. If you selected 2 or 3 data sets e. How do I start? Sets of data from these windows for further processing can be selected or deselected by clicking on the Select hkl The gkl limits on goniostat angles are: Hkll do I stop and start over?

I nearly always do the former. Note the percentage of reflections marked for rejection and the total linear R-factor — they will be very importanf during space group determination. Can I index on peaks collected from several contiguous frames? Do I have to have a. Can I click more than one set of data?

On the lines above primitive triclinic, Denzo permutes and potentially distorts that unit cell to obey the symmetry-mandated requirements for each subsequent Bravais lattice, with highest symmetry toward the top. Where do they go? However with the module boundaries being horizontal — perpendicular to the rotation axis — this might give rise to systematic discs of missing data — and this is likely to be more pronounced in low symmetry space groups at lower resolutions.

The Special Integration and Cryst. The completeness is plotted versus intensity of the reflections. How can I flip through my frames at this stage to see if they all look ok?

Appendix — Installation note. Profile Fitting Radius sometimes needs to be increased for particularly weak or anisotropic data or Denzo will refuse to integrate weak data with insufficent nearby strong spots to estimate the profile from. What are the files that make up the HKL suite, and what do they do? What do the Collect, Denzo, and Scale buttons in each window do?

Now, back to the Collect sub-tab within Collect. Is the number of selected peaks sufficient for indexing? These work well with strong diffractors. Can I rename them? What are all those the Refinement Information values for, and what do they mean?

Wow, my crystal diffracts great! Repeat for a few more frames.

Why would I want to click Scale Sets Only? After the initial round of scaling we can adjust the error model, edit rejection file, check log file, etc.

Select the Scale tab. I think the direct Beam Position is wrong. How do I set the Mosaicity? Setting up Data Hk The final steps are: Once the integration is complete, should I update the site? Related Posts.

Mozragore Select the Scale tab. The per-frame correction factors model ukl that vary primarily with image number, of which primary absorption and scattering effects due to the variation of the volume of the crystal in the beam are the main one, and a B-factor term that potentially models the impact of radiation damage on the crystal manial in scattering with respect to resolution. What if I want to process some of the frames in this set separately? Check again the correspondence between predicted and observed spot centroids. The completeness hlk plotted versus intensity of the reflections.

Vushakar Is the number of selected peaks sufficient for indexing? Profile Fitting Radius sometimes gkl to be increased for particularly weak or anisotropic data or Denzo will refuse to integrate weak data with insufficent nearby strong spots to estimate the profile from. If you turn on absorption correction it will additionally refine an empirical absorption manuaal parameterized as spherical harmonics. Can I click more than one set of data? Normally the correct number is found automatically, but you can use this to exclude ranges of frames at the start or end of nkl set from processing. The main reason to enter it is if you plan on using HKLR to solve your structurefor you not covered here where the sequence is hkl for finding homologs or calculating the expected number of sulphurs. Mosaicity estimates are sometimes problematic for crystals with streaky spots, and if the refined mosaicity climbs too high it will likely cause problems with spot overlaps spots whose centroids are too close to each other on the frame.

Users can also obtain a temporary, free of charge, license to reprocess data collected at synchrotron beamlines. Note: Users from commercial and for-profit institutions, or researchers that would like to use the SSRL provided program for commercial research must have an appropriate commercial HKL license. HKL is still supported! This will launch the HKL window and it will also show information about the other programs running on the machine in a red box as shown in Fig. This box notifies the user about the status of the heaviest-used processors and it can be usually ignored. This window gives access to different programs Indexing, Integration.
