PtychoShelves_EM, source code for multislice electron ptychography

This repository contains codes for multislice electron ptychography. This source code is developed based on an older version of PtychoShelves package from Paul Scherrer Institut (PSI). It was modified for multislice electron ptychography at Cornell University, USA.
