Cheat sheet

Action	why? what to look out for?
1. open terminal and move the window to the left side of the screen. Optional (since this can be done in XDSGUI): cd to an existing XDS directory, or create a new (empty) directory (mkdir <name>). Type 'xdsgui' and move its window so that you still see the left half of the terminal window.	Keeping the terminal window in sight makes it possible to see some output of XDSGUI, e.g. error messages, or the pointless output.
2. click the 'Projects' tab and either choose an existing entry (if there is a list of previous projects) or browse to an existing XDS directory, or create a new (empty) directory	Note that the directory name appears in the title bar of the XDSGUI window!
3. click the 'Frame' tab and load a frame of your dataset. Click 'generate XDS.INP' - this reads the header of that frame, and counts the frames of the dataset. Use Zoom, Contrast and Brightness and move around the frame to evaluate the shape and separation of the reflections: are they smeared or sharp, tiny or broad, regular of broken, symmetric or asymmetric?	watch the green crosshair at ORGX, ORGY, the green circle around it (lower INCLUDE_RESOLUTION_RANGE), the red UNTRUSTED_RECTANGLEs, and the blue TRUSTED_REGION appear
