Mset mset sets up a relationship between molecular states and movie frames. This makes it possible to control which states are shown in which frame. The related command madd appends to the end of a movie. It is identical to the mset command, except for the default value of the frame argument (0 instead of 1). Usage mset specification [, frame ] madd specification [, frame ] Arguments specification = str: state sequence (see below for syntax), or empty string to delete movie {default: } frame = int: start frame, or 0 to append to the end of an existing movie {default: 1 (0 for madd)} Specification Syntax The state sequence specification consists of numbers, and the operators "x" and "-". Spaces between operators are optional. Operator semantic: state x count: Repeat state state for count frames state1 - state2: Iterate from state1 to state2, yields abs(state1 - state2) + 1 frames Formal syntax description: ..→
