[Insight-users] Estimate PCA Model

[Robin Huang]

Hi Again,
Sorry to bother you all, but I've figured it out now. Unfortunately I've ran into another problem. I keep getting a null result "svd[0]: 0 norm: -nan" when I run this sample code. Is there a specific criteria for the input image?

Hi,
I've been trying to make use of the sample code on ITK/Examples/WishList/Segmentation/EstimatePCAModel However, I do not quite understand the required input
if( argc < 5 )    {    std::cerr << "Missing Parameters " << std::endl;    std::cerr << "Usage: " << argv[0];    std::cerr << " nbTrain  trainFilePattern";    std::cerr << " nbModes  modeFilePattern";    std::cerr << std::endl;    return 1;}
What is trainFilePattern and modeFilePattern?
ThanksRobin
