Hi Xiaopeng

this is more a general C++ question than itk, but I guess you can do something like that:

 

(inside the loop)

 

std::stringstream filename;

filename << "D:\\fast_marching_simulation\\3D" << sigma<< ".dcm";

writer->SetFileName( filename.str() );

 

 

thus, adding each time the sigma value to the filename .

 

 

Hope it helps

 

Regards

Hi ITK users,

 

In the fast marching level set method, I tried to program a simulation process for changing parameter “sigma” to get different outputs. Thus I tried for loop. The problem is how to save the different results in different file names. I think I need to change the code of “SetFileName”. If I do not change it, then the later result will replace the previous result automatically. Anyone has any good idea? 

 

for (double sigma = 1.0; sigma <=1.4; sigma += .1) {

 

...

 

writer->SetFileName( "D:/fast_marching_simulation/3D.dcm" );

 

...

 

}

 

Thank you very much!

 

Xiaopeng
