   - run [GrainMapping_assemble_vol.m](https://gricad-gitlab.univ-grenoble-alpes.fr/TomoX_SIMaP/GrainRecon/-/blob/master/GrainMapping_assemble_vol.m), it will generate a .h5 file, a .dream3d file and a .xdmf file, which you can use ParaView for 3D visualization
   - Optionally, you can force this function to use the strategy of "completeness competing" to correct suspicious voxels and compute for empty voxels. By default, grains with fewer than 5 voxels or with seeding completeness lower than a threshold will be checked by this strategy.
 ## 4) Geometry fitting
-  - If geometry is needed to be fitting (this is usually the case with the first time grain reconstruction), run [GrainMapping_geo_fit.m](https://gricad-gitlab.univ-grenoble-alpes.fr/TomoX_SIMaP/GrainRecon/-/blob/master/GrainMapping_fit_geo.m) to fit 7 parameters, including P0y, P0z, dety00, detz00, tilt_x, tilt_y and tilt_z.

   - After geometry fitting, you may repeat steps of 2-3 to redo/refine grain mapping results.<br>
