can't run density.Explain

[mrtn...@gmail.com]

Hi All,

When trying to run an explain.bat file I get a java.lang.NullPointerException after all (17) the environmental layers have been loaded so no GUI is displayed. Can anybody give me an idea of where to look to fix this?

The traceback is as follows:

Loading X:\MaxEnt\Environ\WC1.4\02.5m\Core_x_ER\BIO9.grd

Columns ncols 192

Rows nrows 384

MinX xmin -70

MaxX xmax -62

MinY ymin -30

MaxY ymax -14

Exception in thread "main" java.lang.NullPointerException

        at density.Explain.response(Explain.java:210)

        at density.Explain.<init>(Explain.java:138)

        at density.Explain.main(Explain.java:355)

The command line producing the errors was:

java -mx1820m -cp "/C:/MaxEnt/maxent.jar;C:\MaxEnt\maxent.jar" density.Explain -l X:\MaxEnt\ ... \C_tupizensis_0.lambdas X:\MaxEnt\ ... \C_tupizensis_0.grd X:\MaxEnt\Environ\WC1.4\02.5m\Core_x_ER (pathnames abbreviated)

My PC has 16GB of RAM so memory shouldn't be an issue.  

Thanks,

Martin
