Using this as "washouttable" (only medium washout component): 2 twogamma Brain 0.0 2.0 1.0 155.7 0.0 9000 twogamma Bone 0.0 2.0 1.0 155.7 0.0 9000 according to what can be found in the Gate user-manual: <pre>2 [SOURCE 1 NAME] [MATERIAL 1 NAME] [Mf VALUE] [Tf VALUE IN SEC] [Mm VALUE] [Tm VALUE IN SEC] [Ms VALUE] [Ts VALUE IN SEC] [SOURCE 2 NAME] [MATERIAL 2 NAME] [Mf VALUE] [Tf VALUE IN SEC] [Mm VALUE] [Tm VALUE IN SEC] [Ms VALUE] [Ts VALUE IN SEC] </pre> Gate tells me this: [Actor-0] GateWashOutActor -- ReadWashOutTable : fileName: washouttable.txt [Actor-0] WARNING :: Total WashOut Ratio non equal to 1.
