Hi Miri,
.mat file import in MITK is not supported. You would either need to
export your matlab datastructure as vtk file format (maybe this site can
help you with that: http://www.exolete.com/recipes/matlab_vtk) or you'd
have to find some other way to import your data into mitk. If its just a
list of points it should not be too difficult to read the file using
fstream.

Dear Peter,
Thank you very much for your kind and detailed explanation.
Please forgive me about the following q:
my fiber's data (fibers.mat) is represented as a structural object in
Matlab.
Does Mitk enable to import such a Matlab's data?
Anyway, how my program can read the data from that fiber.mat file?
Thanks in advance.

Hi Miri,
to represent fiber tracts we use mitkFiberBundleX. This
datastructure is simply initialized using a vtkPolyData containing
all your fiber data.
Simple example:
vtkSmartPointer<vtkPolyData> fiberPolyData =
vtkSmartPointer<vtkPolyData>::New(); // the input datastructure
for mitkFiberBundleX
vtkSmartPointer<vtkCellArray> fiberContainer =
vtkSmartPointer<vtkCellArray>::New();
vtkSmartPointer<vtkPoints> pointContainer =
vtkSmartPointer<vtkPoints>::New();
for (int l=0; l<numlines; l++) // iterate over fibers
{
vtkSmartPointer<vtkPolyLine> fiber =
vtkSmartPointer<vtkPolyLine>::New();
for (int p=0; p<pointsInLine; p++) // iterate over points in fiber
{
vtkIdType id =
pointContainer->InsertNextPoint(yourPoint); // add next point
fiber->GetPointIds()->InsertNextId(id); // add point id
to fiber
}
fiberContainer->InsertNextCell(fiber); // add fiber to
fiber container
}
fiberPolyData->SetPoints(pointContainer);
fiberPolyData->SetLines(fiberContainer);
mitk::FiberBundleX::Pointer fiberBundle =
mitk::FiberBundleX::New(fiberPolyData);

Hi All,
How I should convert my fibers which is represented in .mat file
in order to be represented on mitk view?
i.e., I'd like to view my data as :
http://www.dkfz.de/de/mbi/images/neuro3.jpg
Note that my .mat file consists of [n] number of fibers which
each fiber [i] consists of number of points [j] like this:
fibers[n]
|
|__fiber-i__
|
|___point-j(x,y,z)
Please don't hesitate to ask if a further explanation is required ...
Anyway, any information/ method would be very appreciated!
Miri
