Dear Young,

 

I’m very sorry to take so long to reply. I have been travelling and in meetings for most of the past month. This will finally end this week. I can look at this problem in detail next week.

 

I believe you are correct that there is nothing wrong with your files. I suspect the problem is that MGET did not anticipate that ArcGIS might use a negative number to represent the “no data value” in some of the simulation rasters. The error message comes from a function in the Python numpy package that MGET is using to compute some counts. That function requires there be no negative numbers in the input data. I suspect that MGET needs to change the negative value representing “no data” to zero before calling the numpy function. But I will get back to you next week about it.

 

Best regards,

 

Jason

Dear sir,

 

I came across an error message "The first argument of bincount must be non-negative" after executing "Visualize Larval Dispersal Simulation Results (2012). I couldn't find anything wrong with my files. I believe all values and counts are non-negative. I would really apprecate it if you could help me with this. A whole error message is copied and pasted below. I also attached my three raster files.

 

Thanks,

 

Young
