5 Initialization and bootstrapping
6 ================================
7
8 There are three ways to start PISM:
9
10 - option :opt:`-i` reads a previously-saved "complete" PISM model state in a NetCDF file,
11 or
12 - option :opt:`-i` :opt:`-bootstrap` reads an "incomplete" NetCDF file and uses heuristics
13 to fill in needed fields, or
14 - one of the executables ``pisms`` or ``pismv`` is used to initialize simplified-geometry
15 experiments or verification tests from formulas in the source code, and thus no input
16 file is required.
17
18 One of the first two choices is required when using the executable ``pismr``. Modeling
19 usually starts with the ``-i input.nc -bootstrap`` option because real ice sheet
20 observations are never complete initial conditions. Runs with multiple stages often use
21 the :opt:`-i` option after the first stage.
