Quick start: QUB Online Fitness X-Means Movie Maker
QMJ format encodes a QUB state model in JavaScript Object Notation (JSON). Here's an example:
{
    "channelCount":1,
    "IeqFv":false,
    "balanceLoops":true,
    "vRev":0,
    "states": [
	{"Class":0,"Pr":0,"x":25,"y":50,"Label":"","Index":0},
	{"Class":1,"Pr":0,"x":75,"y":50,"Label":"","Index":1}
    ],
    "classes": [
	{"Amp":0,"Std":0.1,"Cond":0,"CondStd":0.1,"Index":0},
	{"Amp":1,"Std":0.1,"Cond":10,"CondStd":0.1,"Index":1}
    ],
    "rates":[
	{"From":0,"To":1,"k0":10,"k1":0,"k2":0,"Ligand":"","Voltage":"","Pressure":"","Index":0},
	{"From":1,"To":0,"k0":100,"k1":0,"k2":0,"Ligand":"","Voltage":"","Pressure":"","Index":1}
    ],
    "constraints":[
	{"Type":"FixRate","States":[1,0],"Index":0}
    ],
    "modelName":"twostate",
    "modelAbout":"Basic closed-open model, with a constraint fixing the value of k0 closing"
}
