I am still having difficulties converting a numpy array to a raster.
I have created a raster for my cell sizes and have found the latitude min and longitude min for the lower_left_corner and use the following code:

from numpy import *
myarray=genfromtxt("E:/test/rasterise/myfile.txt")
mylon=genfromtxt("E:/test/rasterise/LATout.txt")
mylat=genfromtxt("E:/test/rasterise/LONout.txt")

corner=arcpy.Point(139.8, -39.2)
myRaster=arcpy.NumPyArrayToRaster(myarray, corner, mylon, mylat)

but I receive an error message:
Runtime error <type 'exceptions.TypeError'>: Argument x_cell_size: Expected a numeric value, Raster instance or path name.

however the documentation says that you can use a raster for the cell size. Not sure where I am going wrong here.
Any feedback will be greatly appreciated.
