sas.qtgui.Perspectives.Inversion.DMaxExplorerWidget module

Dialog panel to explore the P(r) inversion results for a range of D_max value. User picks a number of points and a range of distances, then can toggle between inversion outputs and see their distribution as a function of D_max.

class sas.qtgui.Perspectives.Inversion.DMaxExplorerWidget.DmaxWindow(pr_state, nfunc, parent=None)

Bases: PyQt5.QtWidgets.QDialog, sas.qtgui.Perspectives.Inversion.UI.DMaxExplorer.Ui_DmaxExplorer

closeEvent(event)

Override close event

modelChanged(item)

name = 'Dmax Explorer'

setupMapper()

setupModel()

setupSlots()

setupValidators()

Add validators on relevant line edits

sas.qtgui.Perspectives.Inversion.InversionLogic module

class sas.qtgui.Perspectives.Inversion.InversionLogic.InversionLogic(data=None)

Bases: object

All the data-related logic. This class deals exclusively with Data1D/2D No QStandardModelIndex here.

add_errors(sigma=0.05)

Adds errors to data set is they are not available. Uses \(\Delta y = \sigma | y |\).

computeDataRange()

Wrapper for calculating the data range based on local dataset

computeRangeFromData(data)

Compute the minimum and the maximum range of the data return the npts contains in data

data
