ePSIC Submitter GUI

A modern, high-performance Streamlit-based web graphical user interface for raw MIB data conversion and Slurm cluster job submission at ePSIC.

This application replaces the older Jupyter-notebook-based ipywidgets interface with a clean, web-based workflow, grouping tasks into logical pages:

1. MIB to HDF5 Conversion: Submitting raw MIB files for cluster conversion to HDF5.
2. Virtual Images (py4DSTEM): Creating virtual images and viewing metadata of converted HDF5 files.
3. Ptychography (PtyREX): Generating PtyREX configurations, dynamically editing parameters, and submitting batch/single reconstruction jobs to the GPU cluster.
4. Calibration & Transformation: Running automatic gold diffraction ring calibration and polar-elliptical coordinate transformations.

Installation

To install the package in editable mode:

pip install -e .

Running the Web App

Once the package is installed, you can start the GUI from any directory by running:

epsic-gui

Alternatively, you can run it directly using Streamlit without installing:

streamlit run app.py

This will launch the app in your default browser (typically at http://localhost:8501).
