Montage viewer

The montage viewer is a GUI that shows simultaneously several z-slices of a volume or volume region..The most usual application of the montage viewer is for the annotation of membrane models, as explained with detail in the walkthrough linked here.

Montage view GUI

The montage viewer works as a sliding window on a number of z-levels. When the montage viewer is invoked, the user selects the separation of the z-levels, which will stay constant during a session of the GUI.

dtmslice Basic controls in the montage viewer GUI

dtmslice Toolbar controls in the montage viewer GUI

Selected frame

The frame in red is the z-level where you can add points to the model currently active in the model pool. Clicking on a frame label or secondary clicking on an image will activate the corresponding label.

Mouse and click controls

Controls are available if:

• there is an active model defined, and.
• the clicker icon in the toolbar is pressed

In this case, the controls are

• [main click on image] : adds point to active model
• [secondary click on point] : menu of options on a model.
• [secondary click on image] : activates the z-lebel.
• [mouse wheel] : zoom in and out
• [keep secondary click pressed + mouse movement] : drag scene.
• [d] : delete closest point to cursor
• [m] move closes point to cursor position
• [backspace] delete last added point

Image appearance

You can control the appearance (bandpass and number of projected slices) on the depicted z levels. Sometimes the default parameters in the montage viewer don't make the scene visible (as the viewing parameters from dtmslice are not automatically inherited).

Transforms menu allows controlling bandpass and projection thickness.

Invoking the montage viewer

From dtmslice

A montage can be opened through the [Montage] option in the menu (for the full scene), or creating a box ([v]), reshaping it and then secondary clicking on it.

From the Catalogue GUI

Secondary click on tomogram names in the dcm GUI will allow to open montages directly on them without previous access to dtmslice

From the command line

This functionality is not yet released.
