I use a raster calculator to get Flow Accumulation above 3000 or 5000.

But it could not execute.

I have done this calculator with other rasters many times and they all worked out very well.

I don't know why this time is not ok.

I googled it but could not find a solution.

Please help me out of this.

Thank you very much.

what was the raster calculator expression?  you have scrolled to the bottom of the error and not shown the full error message.

Doe it just fail for esri grid output? or did you try saving to a *.tif in a folder?

Thank you, Sir. It is very helpful.

I did not save it as a .tif. 

It worked out when saved as .tif.

I will find out why.
