Netgen coordinates conversion from world coordinates to 3D mesh

Hello everybody,

I use netgen to create a 3D mesh from a STL in world coordinates, based on a segmentation from a brain using 3D slicer. It seems I have a mismatch between my stl coordinates and my .mesh ones, hence my question. Is there any kind of coordinate transformation when going .stl->.mesh that would be done by netgen. Additionally, is there a way to ensure I remain in world coordinate when converting to .mesh?
