We have put together a few tutorials to get you quickly started with GenGIS.
Tutorial 0: Obtaining Custom Digital Elevation Maps (DEM)
The simple way to obtain DEMs suitable for use in GenGIS is described here. An older set of instructions on how to manually contruct a custom DEM is available here. You can also obtain 2D maps compatible with GenGIS using MapMaker.
Tutorial 1: Banza Katydids of the Hawaiian Islands
In this tutorial, we consider the phylogenetic tree of Banza katydids (acoustic insects) from the Hawaiian Islands recently recovered by Shapiro et al., 2006. GenGIS will be used to investigate whether or not this phylogeny is related to the geography of the Hawaiian Islands. This tutorial gives an overview of the GenGIS interface, demonstrates how to load data, and illustrates how to change the visual properties of a map, location markers, and trees. The tutorial concludes with an analysis which suggests geography has had a substantial influence on the evolution of Banza katydids.
Tutorial 2: Marine Microbial Communities from the Atlantic Seaboard
In this tutorial, we examine samples collected as part of the Global Ocean Sampling expedition (Rusch et al., 2007) in order to investigate the influence of environmental factors on the composition of microbial communities from marine ecosystems.
Tutorial 3: Custom Data Visualizations and Movies
We have put together a number of examples illustrating how custom data visualizations and movies can be created using the API exposed to the Python console:
- Short examples of using the API are available in the GenGIS manual.
- An example showing how GenGIS can be used to visualize the mobility rates of HIV-1 subtype B in Europe as proposed by Paraskevis et al. (2009) has been posted here. This example includes a Python class demonstrating how a custom visualization can be made.
