you can't have half a row of data.
rows must be an integer.

Ahh - so there's an error in the UI, which says:
Number of rows: (rows, float, optional)
Number of columns: (columns, float, optional)

It may be that rows and columns are floating point on the "inside", but the UI should make it clear that integer values are required! I was trying to fiddle the row/column combinations up and down to get the file size right ...

Thanks for the effort, will run in the new version later on (some work to do first), and see what happens.

so there is. now fixed in SVN.

they are really ints on the inside.

no metadata with it?
sometimes the cell-center as coord versus grid confluences as coords
convention can cause the data to be off by 1 row/col from stated size.
