Ubuntu installation instructions

If MeshFix is used for research purposes, please cite the following paper: M. Attene - A lightweight approach to repairing digitized polygon meshes. The Visual Computer, 2010. (c) Springer.

Accepted input formats are OFF, PLY and STL. Other formats (like .msh for gmsh) are supported only partially.

Example

>>> import nipype.interfaces.meshfix as mf
>>> fix = mf.MeshFix()
>>> fix.inputs.in_file1 = 'lh-pial.stl'
>>> fix.inputs.in_file2 = 'rh-pial.stl'
>>> fix.run()                                    
>>> fix.cmdline
'meshfix lh-pial.stl rh-pial.stl -o lh-pial_fixed.off'
