(For performance reasons, we had applied a minimum tolerance for powder ring display this has been reduced considerably in the present version.)įixed an issue with the display of overbar characters for hexagonal and rhombohedral crystals - as seen in the 'Best Fit' auto indexing results list.Įxpanded Structures Library. Weaker powder rings can now be displayed in simulated TEM diffraction patterns. We also provide a workaround for an apparent system issue with prevent the Reflexions List from being correctly updated. When adjusting unit cell parameters via the Simulation Inspector, d-spacings for all reflexions are correctly updated. This version includes miscellaneous fixes and enhancements.

Lozenges can be framed - this setting is controlled by the Show label outline setting in the Labels group of the Display Inspector. Each lozenge is drawn in the background colour (or a label highlight colour if the background colour and the label colour are similar). To resolve this, labels are now drawn inside elegant lozenges, positioned directly over the relevant ring. However, for patterns with closely-separated rings it became difficult to identify which label applied to which ring. Previously, labels were offset from their corresponding rings. SingleCrystal now displays the Miller indices of powder rings in a prettier format - using the same algorithm as CrystalDiffract to ensure that where multiple reflexions contribute to the same powder ring, negative indices are avoided and non-zero h-indices are given priority (thus, in a cubic crystal 100 is chosen over 010 or 001). Lock the offset origin by turning on the Locked property in its track menu.Improved Labelling scheme for Powder Rings. Locking the offset origin prevents it from making any changes to the origin. Note: moving an offset origin moves the actual coordinate system origin with it so that the offset origin's world coordinates remain unchanged. Select and drag or nudge the offset origin to a desired location in the main video view. Moving the offset origin (moves the origin) Note: changing the world coordinates of an offset origin moves the coordinate system origin so that the offset origin's image position remains unchanged. Select the offset origin and enter the desired values in the x and y fields on the toolbar to change its world coordinates. Changing the world coordinates (moves the origin) Select the offset origin and shift-click again to move it to a new location without changing the coordinate system. Once the offset origin is created and marked, you can re-mark it, change its world coordinates or move it to a new image position as described below. The x- and y-components (world coordinates) of the newly marked point is displayed on the toolbar. Shift-click the video to mark the offset point. The offset origin is initially umarked and the toolbar indicates this status in red. Show or hide the offset origins (along with other calibration tools, if any) by clicking the main part of the Calibration button. If desired, you can create more than one. Creating an offset originĬlick the arrow on the Calibration button on the toolbar and select New|Offset Origin to create a new offset origin. This makes it useful for remotely setting the position of the origin, particularly when the origin is outside the video image. When an offset origin is dragged in the main video view, the origin of the coordinate system moves with it in order to maintain the offset origin's assigned world coordinates. This is the opposite of a point mass step, which has a user-defined image position with world coordinates determined by the coordinate system. Tracker Help: Offset Origin Offset OriginĪn offset origin is a point with user-setttable world coordinates whose image position on the screen is determined by the video coordinate system.
