choose_file(path=None)

estimate_file_inversion(alpha, nfunc, d_max, path, q_min=None, q_max=None, bck=False, height=0, width=0)

estimate_plot_inversion(alpha, nfunc, d_max, q_min=None, q_max=None, bck=False, height=0, width=0)

get_context_menu(graph=None)

Get the context menu items available for P(r)

Parameters:

• graph – the Graph object to which we attach the context menu

Returns:

a list of menu items with call-back function

get_npts()

Returns the number of points in the I(q) data

get_panels(parent)

Create and return a list of panel objects

get_perspective()

Get the list of panel names for this perspective

help(evt)

Show a general help dialog.

Todo :replace the text with a nice image

load(path)

Load data. This will eventually be replaced by our standard DataLoader class.

load_abs(path)

Load an IGOR .ABS reduced file

Parameters:

• path – file path

Returns:

x, y, err vectors

load_columns(path='sphere_60_q0_2.txt')

Load 2- or 3- column ascii

on_perspective(event)

Call back function for the perspective menu item. We notify the parent window that the perspective has changed.

perform_estimate()

perform_estimateNT()

perform_inversion()

populate_menu(id, owner)

Create a menu for the plug-in

post_init()

Post initialization call back to close the loose ends [Somehow openGL needs this call]

pr_theory(r, R)

save_data(filepath, prstate=None)

Save data in provided state object.

Todo :

move the state code away from inversion_panel and move it here. Then remove the “prstate” input and make this method private.

Parameters:

• filepath – path of file to write to
• prstate – P(r) inversion state

set_state(state, datainfo=None)

Call-back method for the inversion state reader. This method is called when a .prv file is loaded.

Parameters:

• state – InversionState object
• datainfo – Data1D object [optional]

setup_file_inversion(alpha, nfunc, d_max, path, q_min=None, q_max=None, bck=False, height=0, width=0)

setup_plot_inversion(alpha, nfunc, d_max, q_min=None, q_max=None, bck=False, height=0, width=0)

show_data(path=None, reset=False)

Show data read from a file

Parameters:

• path – file path
• reset – if True all other plottables will be cleared

show_iq(out, pr, q=None)

show_pr(out, pr, cov=None)

show_shpere(x, radius=70.0, x_range=70.0)
