If not, see . - - -Overview --------- - -The most important new features in this version of CrystFEL are: - -- Introduction of "prediction refinement". - -- Scaling and post-refinement with "partialator". - -- New indexing methods: mosflm-cell and asdf. - -- process_hkl --even-only and --odd-only instead of "alternate-stream". - -These new features have individual sections below. In addition, there are many -other new developments. See the ChangeLog or the changes page on the website -for more details. There were, of course, the usual large number of smaller -refinements and bug fixes. - - -Introduction of "prediction refinement" ---------------------------------------- - -A new refinement step has been introduced between the indexing and prediction/ -integration stages of indexamajig. The refinement aims to maximise the -agreement between the predicted spot positions and the peak positions found by -the peak search step, at the same time as putting the peaks as close to the -Bragg condition as possible. This increases the accuracy of spot prediction, -which has positive effects on the downstream processing stages. - -The prediction refinement stage allows the central beam position to move -relative to the entire detector. The required offset for each crystal is -recorded in the stream and can be visualised using scripts/detector-shift. - -If, somehow, the prediction refinement causes problems for you, you can disable -it using the indexamajig option "--no-refine". - - -Scaling and post-refinement with "partialator" ----------------------------------------------- - -The scaling and post-refinement program partialator is no longer considered -experimental in this version. Many users are already finding significant -improvements in their data simply by applying scaling without partiality: - -$ partialator -i my.stream -o my.hkl -y mypg --model=unity --iterations=3 - -A further improvement is sometimes obtained by applying partialities and doing -full post-refinement: - -$ partialator -i my.stream -o my.hkl -y mypg --model=scsphere --iterations=3 - -Note that partialator applies a per-crystal resolution cutoff to stabilise the -scaling calculation. Therefore, you should experiment with different values -for "--push-res". - -Further improvements to partiality modelling, scaling and merging will be -included in the near future. - - -New indexing methods --------------------- - -This version of CrystFEL can make use of the known unit cell algorithm included -with very recent (7.2.0 or later) versions of mosflm. The known unit cell -algorithm is used by default if you provide lattice parameters to indexamajig. -If this isn't what you want, or if it doesn't work well for you, use -"mosflm-nocell" as your indexing method to restore the old behaviour. - -A new indexing method, asdf, has been added. This algorithm is built into -CrystFEL directly, so no temporary files or external programs are needed. - -The old indexing methods "grainspotter" and "reax" have been removed. - - -process_hkl --even-only and --odd-only --------------------------------------- - -When using process_hkl for merging, you no longer need to use "alternate-stream" -to split the stream into two parts in order to calculate figures of merit such -as Rsplit. Instead, simply use the "--even-only" and "--odd-only" options to -merge only even-numbered and odd-numbered crystals from the stream: - -$ process_hkl -i my.stream -o my.hkl1 -y mypg --even-only -$ process_hkl -i my.stream -o my.hkl2 -y mypg --odd-only -$ compare_hkl my.hkl1 my.hkl2 -y mypg --fom=rsplit [..etc..] - -Note that the numbering of crystals for this purpose is simply according to the -order they appear in the stream. For most purposes, this is effectively random. - -Note further that partialator writes the ".hkl1" and ".hkl2" split-merged -datasets for you automatically. - - -API changes ------------ - -The following changes have been made to the libcrystfel API: - -New functions: - - asdf_prepare(), run_asdf(), asdf_cleanup() - - cell_get_volume() - - crystal_{get,set}_Bfac() - - crystal_{get,set,add}_notes() - - detector_has_clen_references() - - {x,y,r}_gradient() - - refine_prediction() - - refine_radius() - - {get,set}_panel() - - {get,set}_flag() - - solve_svd() - -Removed functions: - - select_intersections() - - update_partialities_2() - - get_excitation_error() - - extract_f_from_stuff() - - grainspotter_{prepare,index,cleanup}() - - reax_{prepare,index,cleanup}() - -Changed function prototypes: - - integrate_all_4() - - set_detector_pos() -- cgit v1.2.3
