XDSGUI: Difference between revisions

# on a Mac, you may find a stream of the following error messages in the console window: <code>Jan 31 14:35:17  xdsgui[20939] <Error>: Error: this application, or a library it uses, has passed an invalid numeric value (NaN, or not-a-number) to CoreGraphics API and this value is being ignored. Please fix this problem. Jan 31 14:35:17  xdsgui[20939] <Error>: If you want to see the backtrace, please set CG_NUMERICS_SHOW_BACKTRACE environmental variable.</code> This sounds terrible, but is actually harmless. Since it is a message from Qt (which XDSGUI uses for graphics), ''it does not compromise the XDS data processing in any way''. If it bothers you, just suppress the printout of these messages, by <code>xdsgui 2>&1 | egrep -v 'CoreGraphics|CG_NUMERICS'</code>

# there is a bug in the Jan-2017 version of XDSGUI that prevents it from displaying non-CBF files. The symptom is that the frames appear to be blank. The workaround is: go to (upper left) "Menu"->"Settings"->remove the string "/usr/local/lib64/dectris-neggia.so". The fix is in the Oct-2017 version (thanks Wolfgang!).

# in the COLSPOT tab, one sometimes has to jiggle a bit the border in the middle of the page, between the log output and the two plots, to trigger showing the plots.
