% This script prepares experimental electron ptycho. data for PtychoShelves
|
|
%% Step 1: download sample data from Zenodo:
|
|
% DOI :
|
|
% link:
|
|
% Note: it's a good practice to store data (and reconstructions) in a
|
|
% different folder from fold_slice
|
|
|
|
%% Step 2: load data
|
|
data_dir = '/path/to/file/'; %change this
|
|
dp = h5read(strcat(data_dir,'SupFig1a_MEP_Planar_Interface.hdf5'), '/dp');
|
|
|
|
%% Step 3: any preprocessing steps if required
|
|
ADU = 3661; % Analog to Digital units for EMPAD-1 detector
|
|
dp = dp / ADU; % convert to electron count
|
|
|
|
%% Step 4: save .hdf5 file in the folder structure used in PtychoShelves
|
|
scan_number = 1; %Ptychoshelves needs
|
|
save_dir = strcat(data_dir,num2str(scan_number),'/');
|
|
mkdir(save_dir)
|
|
roi_label = '0_Ndp255';
|
|
saveName = strcat('data_roi',roi_label,'_dp.hdf5');
|
|
h5create(strcat(save_dir,saveName), '/dp', size(dp),'ChunkSize',[size(dp,1), size(dp,2), 1],'Deflate',4)
|
|
h5write(strcat(save_dir,saveName), '/dp', dp) |
