TUFLOW Message 2334

TUFLOW Message
ERROR 2334 - Reading ESRI Grid file or premature end of file.

Alternate Message
ERROR 2334 - Exceeded limit of rainfall grids in file

Message Type
ERROR

Description
This indicates that the ESRI ascii grid file does not contain a valid grid, or the file is incomplete. This file format (usually has the extension .asc or .txt) and is a plain text file (not binary) and can be opened in a text editor. At the top of the file, information on the size of the grid, the cell size and coordinates should be displayed. An example is below:
ncols 2284
nrows 3916
xllcorner 0.0
yllcorner 0.0
cellsize 5.0
NODATA_value -9999
After the header information should follow the ncols x nrows of data. If the file is not in a similar format to the above, the file is most likely not in the correct format.

Suggestions
