[GRASS-user] i.gensigset - constraints to generate a sig file

[Christian Braun]

Dear GRASS users,

I am trying to generate a signature file with i.gensigset as an input for i.smap.
So far I am struggling with the creation of the sig file.
Are there any constraints in terms of minimum number of input pixels per class (related to the input image size)?
Is there a relationship between the number of input images in the image group and the maximum classes you can use for training or classification?

Thanks in advance and greetings from Luxembourg,
Christian
