The Bottom Panel consists of several major features. It can be resized vertically by dragging the blue dotted handle near the top middle of the panel, or collapsed/expanded by clicking once on the same handle. Some features are unavailable in different view modes.

Image Explorer

Image Explorer interface

The Image Explorer displays a preview of the files you have opened. The highlighted preview signifies which one you have clicked on last, not necessarily which is loaded into your current view. Double clicking on a preview image will load it into the view. When an image is first loaded, it will have a spinning icon on it, signifying that it is still being processed by Aivia. This can be caused by a slow hard drive or network, a large amount of data or objects saved into the image, or other background tasks that Windows is working on.

To add and open additional files, you can use the File menu Open dialog, the Open button in the top left of this panel, or drag and drop from a Windows Explorer window anywhere on Aivia. Also see opening an image.

To save an image, if it is the currently open image in the view, you can use the File menu's Save dialog. However, if you have navigated away from that file and now want to save its changes without having to leave your current image, you also can right click on the preview image and choose Save.


Annotations interface

The Annotations tool provides a small set of tools designed to help you measure your image in 2D. The Annotations feature is unavailable in 3D. When appropriate, a histogram is provided for the cross area on the right side. The gear icon opens additional options such as including additional column data such as Mean Intensity or the Standard Deviation Intensity for the area selected. You can also change the color and size in the additional options for the visual representations.

Edit Masks and Tracks

The Edit Masks and Tracks tab lets you edit object outlines and object tracks respectively. The tool can be used to edit either processed data or to create new objects. Measurements are automatically updated on edited objects when toggling a different tab in the Bottom panel.

Edit Masks

The Edit Masks section in the Edit Masks and Tracks tool lets you edit object outlines on an image. The tool provides several objects for drawing editing regions on the image - freehand region, polygon, straight line, freehand line, circle, and a magnetic lasso tool. Once a region has been created, you will have the option to add or remove the drawn region on the designated object set.

Edit Tracks

The Edit Tracks section lets you edit object tracks and their lineages. To activate, click on the Edit Tracks button and select displayed object tracks to pin into the Bottom Panel interface.


Spreadsheet interface

The Spreadsheet is the main method of viewing and pulling facts and information from Aivia. Tabs across the bottom and the drop down in the top right segment the data into expected groups for easier viewing. Selecting a row in the Spreadsheet will also select it in the view when possible, and vice versa. Similar to Windows Explorer, you can multi-select by using Ctrl, Shift, and the Arrow keys. Deleting an entry in the Spreadsheet (press the Delete button on your keyboard) will actually delete the item from the file. You can hit Undo (Ctrl + Z) or reload the file without saving if that happens inadvertently.

Aivia_BottomPanel_Spreadsheet_ExportToExcel.png The export to Excel button allows for exporting data, and opens a window to help you choose what data you would like to export as well as format options (.cvs or .xlsx).

3D Tools

There are four tools in the 3D Tool section: Keyframe Tool, Mesh Creator, Analysis Cube and Mesh Editor.

Keyframe Tool

The Keyframe tool is used for making movies and fly-throughs of your data in 3D view. Move the camera to a position, and click the Add Frame button. Repeat several times. When you hit the Play button, the camera will move one by one between your keyed locations in a linear manner. The number below each pair of frames represents how long the camera will take moving between the two keyed locations. It is suggested to increase to around 5 to 10 seconds for a smoother experience. The camera will pivot along the shortest angle between the two perspectives you keyed the locations with, not along the angles you moved the camera. Place additional keyed locations to make sure the camera is looking in the direction you want.

The export button will export an .avi movie compressed in MPEG4 or Raw by FFmpeg with a bitrate of 1 or 4 Mbps if MPEG4. Options to control format and bitrate are in the Advanced Options dialog. The video size is determined by the current size of your 3D view. Note that the export will take longer or shorter depending on the speed of your computer as all frames are rendered as fast as can be.

Mesh Creator

The Mesh Creator will run Marching Cubes across your volume data set. It first displays a simulation using volume data so you can set the min & max and review the Intensity Chart results. Once you are ready, click Create Largest or hit the drop down next to Create Largest to select Create All. Largest will keep only the largest resulting mesh, All will keep all resulting meshes. The Aivia will pause while Marching Cubes runs, and the 3D view will pause while the new mesh is loaded into 3D. The output will become a new Object Group.

Analysis Cube

The Analysis Cube allows you to work within a subset of your data. Set its position, rotation and size, and click Crop Cube to get another image in the Image Explorer that is of the cropped region. Make sure you save the new image if you want to keep it. The new image will contain a brown rectangle that outlines the original image's data shrunk to your new cube, and the white rectangle represents the same region and angle that the Analysis Cube was in when you cropped. The actual data is the intersection of the two.

Mesh Editor

The Mesh Editor allows you to split a mesh object in two. You can adjust the position, size and rotation of the cutting plane using the on-screen controls on the mesh editor cutting plane. Position the cutting plane at the desired location intersecting a mesh object and click Split to bisect the object at the specified location. The mesh will be updated to enclose the cut surface and measurements will be updated for the mesh.
