Hi, I am a student in physics working on ptychography. For my FPM experiment I need to reconstruct the images so I gave PtyLab a try. Actually I manage to preprocess my datas, reconstruct and the plots look correct. But my problem is that whenever I try to save the results with the saveResults() function (put right after _engine.reconstruct()_ just like in your jupyter tutorial)of the _Reconstruction_ file I keep getting empty datas. This seems to be coming from the self.object array being an empty array of zeros but cannot find why. The same thing happens if I try to plot _reconstruction.object_ directly after the reconstruction. Does anyone have a solution? Or another way to save the reconstructed image in its upscaled resolution? Thank you very much, NG
