Export the Heatmaps

You can export a single heatmap, some heatmaps, or the whole matrix of heatmaps to image files. A great advantage of this function compared to copy and paste is that you can rescale the heatmap to a resolution higher than that of the original video, resulting in quality pictures ready for publications.

Export a Single Heatmap

1. Click the heatmap you want to export, so that its border becomes highlighted in red.
2. Right-click the heatmap and select Export Image, or on the toolbar click the Export Image icon.
3. Select the image Resolution (width x height) in pixels.
4. Click Export. In the Export Image window, enter the name and location of your image file, choose the image format and click Save.

Tip: You can also copy and paste single heatmaps: click a heatmap, right-click and select Copy or press Ctrl+C, then paste the picture to an external program. You cannot copy/paste multiple heatmaps.

Export Multiple Heatmaps

1. Select the heatmaps you want to export.
   • To export all heatmaps in the matrix, make sure that no heatmap is highlighted. Click outside the heatmaps area to remove any selection.
   • To export multiple, non-adjacent heatmaps, hold Ctrl down and click the individual heatmaps.
   • To export multiple, adjacent heatmaps, hold Shift down, then click the first, then the last of the heatmaps you want to export.
   The border of the selected heatmaps becomes highlighted in red.
2. On the toolbar click the Export Image icon. If you have selected some heatmaps, you can also right-click anywhere over the selected heatmaps and choose Export Image.
3. Under Export, choose one of the options: To Separate Image Files or To One Image File.
4. Select the image Resolution (width x height) in pixels. Tip: To ensure that each heatmap has a sufficient resolution, under Export select first To Separate Image Files, select the resolution you require and then choose To One Image File. The image resolution (width, height, or both) is increased by a number of times depending on how many heatmaps are in the rows and columns.
5. Choose Independent Variable as overlay to have the trial information (headers) displayed on the exported images.
6. Click Export. In the Export Image window, enter the name and location of your image file, choose the image format and click Save.

Notes

• The available image resolutions depend on the aspect ratio of the original background pictures. The zoom level chosen for the plots affects the default resolution.
• To choose the appropriate information to display on the heatmaps, see Custom Layout in Arrange Heatmaps.
• The suggested export file name is Heatmap Image plus a progressive number. For heatmaps exported to separate files, the name of the exported file is the name you enter in the Export Image window followed by the row headers and the column headers. For example: Heatmap Image 0001 - Trial 1 - Center Point.

Plot Integrated Data

Overview

Choose Integrated Visualization to visualize a set of tracks obtained from one tracking session (trial), together with video, external data (if applicable), and plots of your dependent variables (including manually scored behaviors and external data). This function is particularly useful when you want to compare tracks with the corresponding video.

Important: You can visualize up to 200 plots at the same time. If the number of subjects/arenas times the number of dependent variables currently selected exceeds this limit, filter the subjects or arenas in your Data Profile, or remove some dependent variables from your Analysis Profile.

Prerequisite

Make sure that the dependent variables you want to plot are specified in the active Analysis Profile.

To Plot Integrated Data

1. Choose Analysis > Results > Plot Integrated Data, or in the Experiment Explorer, under Results, click Integrated Visualization.
2. On the toolbar, choose the Track Smoothing profile, the Data Profile, and the Analysis Profile that you want to use.
3. On the toolbar, choose the selection result and the trial you want to visualize. By default, the first trial is selected. To select the next/previous trial, click the buttons next to the drop-down list. The selection result list is available if your current Data Profile includes two or more selection results.
4. Optionally, customize tracks and plots.
5. View and interpret variable plots.

Notes

• In the Integrated Visualization screen you can also find one or more External Data plots, depending on how many external data files have been imported in that trial.
• Not all playback speeds might be available. Depending on the video format, you may not be able to play the video at a specific speed.
• If your data selection contains nesting criteria, all samples are plotted but the samples excluded by nesting are shown shaded.
• You can visualize up to 200 plots per trial. If the number of dependent variables in your Analysis Profile times the number of subjects/arenas exceeds this limit, a message informs you that not all charts are visualized. Filter the subjects/arenas in your Data Profile, or remove some variables in your Analysis Profile.
• The begin time in the video window is the time of the first sample acquired in all arenas.
• The end time in the video window is the time of the last sample from all arenas. Within each arena, the last sample is marked by the message End of Track over the top-left corner of the corresponding arena.
• For multi-arena setups, the tracks are synchronized; that is, samples of different arenas visualized at a given moment were acquired at the same absolute time.
