I can confirm that it gives such a message (6.4.svn). > howewer the file appear in the subgroup folder Right. The problem is that i.maxlik apparently no longer writes the image statistics. It used to work. What I get (North Carolina example): i.class lsat7_2002_20 group=lsat7_2002 subgroup=lsat7_2002 outsig=testsig GRASS 6.4.0svn (nc_spm_08):~/grassdata/nc_spm_08/neteler/group/lsat7_2002/subgroup/lsat7_2002/sig/ > cat testsig # #water 525 #terrain 897 -> no statistics! Now this would follow but is useless due to the broken sigfile: i.maxlik group=lsat7_2002 subgroup=lsat7_2002 sig=ciao class=class Its error message is unhelpful. In the i.class ChangeLog I don't see relevant changes, so it must be a bug in I_write_signatures() perhaps?
