[Vv] How can I pass a "patient mask" to clitkExtractLung?

[黄成]

Hi all,

         I'm using clitkExtractLung.exe to extract the lung from a CT
image, and I run it using command line: "clitkExtractLung.exe -i
myImage.nii"
         Then I get an error message:

itk::ExceptionObject (00000000009EF4B0)
Location: "Unknown"
File: ..\..\..\Source\clitk\common\clitkImageToImageGenericFilterBase.cxx
Line: 243
Description: **Error** The filter <ExtractLung> is not available for 3D
images with pixel=float and 1 component.
The filter <ExtractLung> manages:
Dim: 3, Type: short

         Since the help information of clitkExtractLung.exe tells me that a
patient mask image is needed, I guess I should pass a patient mask image as
an argument to it. However, I cannot figure out how to do this because
there is no argument for "patient mask". How can I make this work?
