Geez, I feel stupid, I figured out that erd2grass is the r.in.erdas command.
I have replaced one problem with another... this is the output from when I
run erd2grass:
OPTION: Name of erdas input file
key: erdas
required: YES
enter option > kong
You have chosen:
erdas=kong
Is this correct? (y/n) [y]
OPTION: The files for the n bands will be:
grasscellfile.1 ....... grasscellfile.n
key: prefix
required: YES
enter option > kong.1
You have chosen:
prefix=kong.1
Is this correct? (y/n) [y]
Error can not open ERDAS file
I have the erdas files stored under ./data/acheron/stacey/erdas
with rw-r-r permissions. Where does erd2grass look for the data files?
