This paper describes the program snapin which is used to prepare data for transport analysis with the snap code. The data input to snap includes diagnostic profiles [ne(R), Te(R), Ti(R), vφ(R), Zeff(R), Prad(R)] and measurements such as total plasma current, Rmajor, beam power, gas puff rate, etc. snapin reads in the necessary TFTR data, allows editing of that data, including graphical editing of profile data and the selection of physics models. snapin allows comparison of profile data from all diagnostics that measure a quantity, for example, electron temperature profiles from Thomson scattering and electron cyclotron emission (ECE). A powerful user interface is important to help the user prepare input data sets quickly and consistently, because hundreds of variables must be specified for each analysis. snapin facilitates this by a careful organization of menus, display of all scalar data and switch settings within the menus, the graphical editing and comparison of profiles, and step-by-step checking for consistent physics controls [J. Murphy, S. Scott, and H. Towner, The snap User's Guide, Technical Report PPPL-TM-393, Princeton Plasma Physics Laboratory (1992)].
