→Libraries and software that the program depends on: small fixes
* 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
would conserve the inode. I would be glad to receive feedback if this helps - then the bug could 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") may be used for commands, e.g. running [[pointless]] against the XDS_ASCII.HKL file. The user-definable commandline may be used e.g. for
==== Libraries and software that the program depends on ====
RedHat Enterprise Linux 8 (CentOS 8) does not seem to provide by default the needed Qt libraries. They can be installed using
dnf install https://extras.getpagespeed.com/redhat/8/noarch/RPMS/getpagespeed-extras-release-8-6.el8.gps.noarch.rpm
In addition, the qt-settings RPM may have to be installed. It is available from EPEL, or also from Fedora 29.
'''Ubuntu''' needs the libglu1-mesa package if you get the error message
