[GRASS-user] Create Manning's n map

[Rich Shepard]

   For the defined region I want to create a map of the Manning's n friction
value (0.030) in each cell. v.in.ascii tells me it cannot find the input
text file:

v.in.ascii -n -b input=manning.txt output=manning format=point
ERROR: Unable to open input file <manning.txt>

   The file has no coordinates, only the single value 0.030. I am not finding
what is missing here. A pointer is needed.
