[Gate-users] washout actor

[Rohling Heide]

Dear Gate-community,


could you please help me with the washout actor that I am trying to apply to a back2back source. 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:


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]


Gate tells me this:


[Actor-0] GateWashOutActor -- ReadWashOutTable : fileName: washouttable.txt
[Actor-0] WARNING :: Total WashOut Ratio non equal to 1.

    Ratio Second WashOut Component: 155.7
    Half Life Second WashOut Component (ns): 0
    Ratio Third WashOut Component: 0

What is wrong? Is there an example for a correct washouttable available (order and units of entries)?

 Thank you, Heide
