Save data as ASCII

Is there an option to save data as ASCII instead of binary?

Thanks!

You can get the voxel data as numpy array and write that to a text file. But it would terribly inefficient, van be 10-100x slower read/write than binary.

Thanks, professor Lassoan. Is there any python code for numpy to read a stl file in 3d slicer?

You can load STL file using slicer.util.loadModel() and then get point coordinates or scalar values as numpy array by calling slicer.util.arrayFromModelPoints() and slicer.util.arrayFromModelPointData().
