What is the ArcGIS error? I tried these files on ArcMap 9.3 and 10.0 and had no issues that I realized. (to display in a meaningful manner, I had to change the symbology which required the calculation of statistics in ArcGIS. I also changed the cellsize to .1 so I could more easily examine the pixels and values.) Below looks like a 3x4 grid that is labeled as 5x5 but even that worked for me in ArcGIS (didn't throw error but values were not where 'expected'). > > > ncols 5 > nrows 5 > xllcorner 100.000000000000 > yllcorner 100.000000000000 > cellsize 0.000010000000 > 1 1.4809201955795288 1.4809201955795288 > 0.25947147607803345 0.71342569589614868 2.8101832866668701 > 0.11773009598255157 0.15476560592651367 0.86710774898529053 > 0.17429724335670471 0.76037305593490601 10 0.74458205699920654 > All 4 of of Even's files worked for me too.
