diffpy.fourigui package

Tool for visualizing 3D diffraction and PDF Images.

Submodules

diffpy.fourigui.fourigui module

class diffpy.fourigui.fourigui.Gui(*args: Any, **kwargs: Any)

Bases: Frame

animation()

slices through the 3D array along the selected axis

applycutoff()

shape the reciprocal-space array

reassign all voxels with distance smaller than qmin and greater than qmax to np.nan.

parameters:

qmin, qmax is loaded from the qmin, qmax input panel currently operates in units of pixels

Returns:

nothing

colorrange_upd()

change color range in plot

fft()

Fourier transform 3D array from reciprocal to real space the origin of reciprocal and real space is expected to be the central voxel

ifft()

Inverse Fourier transform 3D array from real to reciprocal space the origin of real and reciprocal space is expected to be the central voxel

initUI()

Initialize the GUI for fourigui

intensity_upd_global()

Load global intensity minimum, maximum and sum of 3D array

intensity_upd_local()

show local intensity minimum, maximum and sum of current plotted plane

load_cube()

loads 3D array in h5py file format from the filename input panel 3D array is expected to be a reconstructed reciprocal scattering volume when executed, one slide perpendicular to the selected axis will be plotted in the plot panel

multiple_funcs()

Executes multiple functions passed as arguments in sequence.

newcutoff()

Apply a new cutoff based on the current space and cutoff settings.

plot_next_plane()

Plot the next plane in the dataset, looping back to the first if at the end.

plot_plane()

update plotted plane perpendicular to the selected axis

redocutuff()

Redo the cutoff operation depending on the current space (real or reciprocal).
