262- Downloading and Installing
27
28        2.1- System Requirements:
29                - Python version >= 2.4 should be running on the system
30
31        2.2- Installing:
32                - Get the code from svn://danse.us/sans/releases/sansmodels-0.4.0
33                - Execute the following:
34                        python setup.py install
35
363- Known Issues
37
38        3.1- All systems:
39                - Q range validity of I(q) calculations.
40                        Our 1D models of I(q) use the function of the NCNR library
41                        for their IGOR package (Klein, 2006). That library uses a
42                        fsat integration technique in some of its models (cylinders
43                        and ellipsoids). Integration is done using 76 points in the
44                        angle between the axis of the object and the q-vector, which
45                        translates in a larger inaccuracy at high q. Integratiing
46                        the 2D model I(q,phi) over all orientations of the object
47                        will not yield the exact same result as the NCNR calculation
48                        for q > 0.3 A-1.
49                - Refactoring needs to be done to update the model base class.
50                  We should get rid of the useless arithmetics and store the parameters
51                  as class objects rather than values. This would eliminate the multitude
52                  of dictionaries needed to store all the various aspects of a parameter
53                  (limits, units, dispersity information). The C++ design it relies
54                  on is much cleaner in that respect, but it still depends on the old
55                  C computation. Those should be incorporated in the C++ classes.
