This normally means that a list, a set or something else that consists of more than one element was expected. One possible cause for this error message is a construct of the following type:
(%i1) l:[1,2,3]; (%o1) [1, 2, 3]
(%i2) append(l,4); append: argument must be a non-atomic expression; found 4 -- an error. To debug this try: debugmode(true);
The correct way to append variables or numbers to a list is to wrap them in a single-element list first:
(%i1) l:[1,2,3]; (%o1) [1, 2, 3]
(%i2) append(l,[4]); (%o2) [1, 2, 3, 4]
