How to save high resolution images (OSX)

• Use 'Screenshot' to capture the screen and copy it to the clipboard, making sure the EvoLaps map is displayed at its maximum size.
• Open 'Keynote', select a basic slide type, and resize it (for example, to 4000px x 4000px in the 'Document' section).
• Paste the clipboard content onto the Keynote slide, annotate if necessary, group all elements, and then copy them (press Command-C).
• Open 'Preview'. From the 'File' menu, select 'New from Clipboard'.
• Save the image as a PDF or PNG file. You can adjust the size and DPI of the image. If resizing, uncheck 'Resample image' to keep a high DPI (> 300 dpi).

How to save high resolution images (Chrome)

• Open DevTools (bottom of the “View” menu)
• From the DevTools, go to the “Elements” tab
• In the DOM tree, locate and expand the element named makeitmove1
• Select the div with the id "geographicmap"
• Right-click on that line in the DOM tree and choose “Capture node screenshot”
• Chrome will generate and download a PNG of exactly that container—map background included—pixel-perfect
• Press 'Ctrl +' keys to increase the global scale (eg 500%) of the entire web interface (make sure to zoom in/out slightly afterwards to refresh the rendering)

Problems with the import phase

Issues may occur during the import phase due to differences in software versions or analysis options, which can affect how data are structured in the NEXUS file.
To resolve common problems, open your NEXUS file and check the following:

• The 'location1' and 'location2' variables should store the latitude and longitude of sample locations, respectively.
• The 'location1_median' and 'location2_median' variables should store the latitude and longitude of ancestral locations.
• The 'location1_xx%HPD' and 'location2_xx%HPD' variables represent uncertainty areas, corresponding to xx% credibility regions.

If editing the file does not resolve your issue, please contact me. This will help me review and improve the EvoLaps parser used during the import phase.

MapBox and OpenStreetMap copyright

EvoLaps uses MapBox and OpenStreetMap for map display. For scientific publication :

• check on the display of the copyright of MapBox and OpenStreetMap on the map (see DATA tab, preferences section)
• you can also add the figure comment with the following statement: "Prints use map data from Mapbox and OpenStreetMap and their data sources. To learn more, visit https://www.mapbox.com/about/maps/ and http://www.openstreetmap.org/copyright"

For a printed map and similar media (that is ebooks, PDFs and so on), the credit must appear beside the map if that is where other such credits appear, or in a footnote/endnote if that is where other credits appear, or in the “acknowledgements” section of the publication (often at the start of a book or magazine) if that is where other credits appear. The URL to openstreetmap.org/copyright must be printed out.
