* The second item ("Saving and comparing good results") offers commands to save/restore the current data processing files to/from a "save" directory. Make sure to replace "xdiff" with "xxdiff" or "tkdiff", if one of the latter is available. If [http://www.globalphasing.com/autoproc autoPROC] is installed, I suggest to use the "User defined command 2" for <code>mkdir staraniso; cd staraniso; aP_scale -hkl ../XDS_ASCII.HKL; echo anisotropy-corrected files are in staraniso subdirectory</code>.

* The third item ("Optimizing data quality") offers commands that manipulate [[XDS.INP]] in several ways. Please note: the popup "XDS.INP has been changed externally" is emitted by the Qt system and cannot be switched off. It appears if one of the scripts changes XDS.INP while it is opened by XDSGUI (which is always the case) . Thus, one should simply press the "Reload" button. XDSGUI sometimes hangs (and must be killed with Ctrl-C) when running <pre>grep _E INTEGRATE.LP | tail -2 >x; sed -e 's/ BEAM_DIVERGENCE=/! BEAM_DIVERGENCE=/' -e 's/ REFLECTING_RANGE=/! REFLECTING_RANGE=/' XDS.INP >>x; mv x XDS.INP</pre> I suggest to replace the final part of the latter command <pre>mv x XDS.INP</pre> with <pre>cat x > XDS.INP; rm x</pre> because this workaround conserves the inode. This bug will be fixed in the code. The user-definable command may be used e.g. for <pre>echo RELRAD=7 ! default is 5 >x; grep -v BEAM_DIVERGENCE XDS.INP >>x; cat x > XDS.INP; rm x</pre> This provides more pixels to the background estimation (for another INTEGRATE), and is useful for weakly exposed data sets which have mostly pixels with zero counts.

* The last item ("Further analyses") offers useful commands. "determine spacegroup with pointless" runs [[pointless]] against the XDS_ASCII.HKL file. The button "show spots in reciprocal space" runs [[spot2pdb]] to show you the reflections of SPOT.XDS in reciprocal space, with coot. You see the reflections that could be indexed in IDXREF in yellow, the not-indexed ones in pink, the rotation axis in blue and the origin as a blue cross. Ice rings and additional lattices can be easily identified - see [[spot2pdb]] for examples!
grep -s allow-duplicate-sequence-numbers ~/.coot || echo "(allow-duplicate-sequence-numbers)" >>~/.coot ; spot2pdb -r 1; coot SPOT-*.pdb
