The remaining control file for GAMIT is :file:`autcln.cmd`.
It is complicated but can almost always be left unchanged.
Cases for which you might want alter the default settings include data from codeless receivers, stations for which you cannot get *a priori* coordinates better than 10 m, or short sessions (< ~ 3 hours).
For a detailed discussion of the :program:`autcln` settings, see Section 4.2 of the `GAMIT Reference Manual <http://geoweb.mit.edu/gg/docs/GAMIT_Ref.pdf>`_.
