Hi Tim Thanks for the quick reply -- what is the format of the "label-list-file"? I've generated a text file of <value> <red> <green> <blue> <alpha> rows (1 row for each new label), without the <labelname> part, and am getting:
"ERROR: label list file is malformed for entry #91" (which corresponds to the last row in my file), even though this row is the same format as the others. Thoughts?
