Reflection view properties

Choose Refln view props... in the Edit menu to display a dialog box with the current reflection view properties. The view properties include Symbol, Size, and Color. In most cases the values set in this dialog do not take effect until either the OK or Apply button is selected. Also, if no image is currently displayed, then settings made in this dialog box have no effect. Selecting Help activates the HTML viewer for on-line help.

Reflection symbols are plotted centered on the observed pixel position if available or on the calculated pixel position. If both observed and calculated positions are available, then the symbol is centered on the observed pixel position and a vector is drawn to the calculated pixel position.

Rejected reflections

Reflections which are flagged as in a bad nonuniformity region or as overlapped are drawn in RED regardless of the selected color. They are also drawn with a triangle shape superimposed upon the selected symbol.

Symbol
Select the symbol used to draw reflections with.
+ sign
All reflections are drawn with a plus sign.
x
All reflections are drawn with an x sign.
o
All reflections are drawn with a circle or ellipse.
[]
All reflections are drawn with a square or rectangle.
o and []
If rocking curve information (rotation angle start and end for each reflection) is available in the reflection list, then reflections with rocking curves that intersect the displayed image are drawn as circles, and reflections with rocking curves that do not intersect the displayed images are drawn as squares. During a dtintegrate run, one should see spots in circles and background in squares. In effect, squares indicate the padding in a shoebox. If one sees spots in squares, then the crystal mosaicity may be set too low. If one does not see spots in some circles, then the crystal mosaicity may be set too high.

If rocking curve information is not available, then all reflections are drawn as circles.

o and no []
If rocking curve information (rotation angle start and end for each reflection) is available in the reflection list, then reflections with rocking curves that intersect the displayed image are drawn as circles, and reflections with rocking curves that DO NOT intersect are NOT displayed. One may not see reflections used in refinement in this mode because they may not intersect the currently displayed image.
Size
Enter the size of the symbol in pixels. If you enter 1 number, then the second dimension is set equal to the first.
Color
Set the color of the symbol. Reflections which are flagged as in a bad nonuniformity region or as overlapped are drawn in RED regardless of the selected color.

Deleting spots: Click on a spot, then use the -, delete, or backspace key to delete the spot.

Adding spots: Click on a spot, if integrated successully, then use the + or Insert key to add the spot.
