Niche Analyst setup & installation on Windows

How to install Niche Analyst on Windows. ------- http://biodiversity-informatics-training.org/software-data-sources/nichea/ Niche Analyst (NicheA) is an open-source, cross-platform application released under a GNU Public License (GPL). NicheA is written in Java, combining several toolkits, such as R, Weka, JAMA, GDAL and QuickHull3D. The platform is a window-based, user-friendly application that executes on most common operating systems, including Microsoft Windows, Mac OS X, and some Linux releases, such as Ubuntu. Users can use NicheA (1) to re-orient and re-cast environmental variables through principal component analysis (PCA), (2) visualize species' distributions in linked E and G spaces, (3) design barriers to dispersal in G, (4) estimate and display Grinnellian niches in E, and (5) map objects between G and E. Fig. 2 shows functions and feasible action flows in NicheA. NicheA can also import and display results of widely-used ENMs, and export SDSs in formats compatible with various ENM platforms. The unique functionality in NicheA, not available in other software programs, is that of estimating Grinnellian niches of species based on environmental variables and occurrence records, but with a clear focus on fundamental ecological niches. We have implemented two algorithms, a minimum volume ellipsoid (MVE) and a convex hull, both designed to approximate the full dimensions of fundamental niches via approximation of convex shapes in multivariate environmental spaces. NicheA can display ecological niches; calculate their shape, density, location, and other attributes; and quantify similarity among multiple niches based on MVE overlap. A few studies have used convex hulls to estimate niches, but this approach has not been implemented easily owing to the complexity of its formulas.
