# 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.

Result: 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 + 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.
