dtmslice or dynamo_tomoslice is the current main tomogram browser inside Dynamo.
The main axis in the figure will show a slice across a volume. The volume is kept in memory. In general, volumes with effective dimensions of 1000k x 1000k x 400 voxels are depicted efficiently by the Matlab renderer, i.e., you can move the depicted slice across the volume reasonably fast. Here effective means that we are are referring to the volume actually stored as a matrix in the memory of the browser. Thus, if you want to visualize a tomogram file with a dimension of 4k x 4k x 1k pixels you probably want to visualize it trough a binned proxy.

Invoked through the press of [-] or [+]. The tomogram scene must be selected. Should turn the arrow cursor into a cross cursor. When the magnifying icons in the toolbar are active, you can use the mouse wheel to zoom in and out of the scene.
The zooming state can be interrupted by pressing [space] or invoking any other viewing control (through [r] or [p]).
Rotation of viewing angle
Invoked through pressing [r]. The cursor should turn into a circling arrow. In this state, moving the mouse while keeping the main button pressed will change the point of view of the scene.
This state can be interrupted by pressing [space] or invoking any other viewing control, through [-], [+] or [p].
[p] activates the panning tool, which allows you to drag the scene. When active, the cursor arrow appears as a hand symbol.
Creating new models
Importing models from catalogue
Saving models into the catalogue
Models currently in memory (i.e., in the model pool) can be edited. Only the model that is currently active in the windows can be edited.
Adding points into a model
The key [c] adds a point to the currently active model.
Adding a center point into a model
The key combination shift+[c] adds a center point into the currently active model, if the model accepts a center property (like is the case for vesicles and surfaces).
The key [delete] will delete the last point inside a model (it can be used repeatedly to delete all points in the model in reversed creation order). To delete other points, secondary click on it and use the delete point option in the menu.
