[GRASS-user] about i.gensigset warning message

[P.T.M Thy]

Hi all,

I ran i.gensigset to make the training map for SMAP-classification but I had
several warnings as below:

Warning: Removed a singular subsignature
I am running GRASS-6.2.3 on linux. Can someone tell me what this warning
means.

Thanks in advance

Mai Thy
