Alternative reconstruction engines alternative
Beyond SHARP, several sections expose reconstruction engines directly, useful for method development and comparison.
py4Dstem — direct py4DSTEM reconstructions
| # | Title | What it does |
|---|---|---|
| 10 | Parallax reconstruction | Performs a parallax (tilt-corrected bright-field) reconstruction. |
| 20 | Parallax Analysis | Analyses the parallax reconstruction result. |
| 50 | Singleslice ptychography reconstruction | Performs a single-slice ptychography reconstruction. |
| 60 | Parallax reconstruction (draft) | A draft/raw variant of the parallax reconstruction. |
Torchslice — PyTorch-based tools
| # | Title | What it does |
|---|---|---|
| 10 | Neighbour correlation alignment | Aligns patterns by neighbour cross-correlation. |
| 15 | Parallax reconstruction | Performs a parallax reconstruction. |
| 20 | Shadow Montage | Computes shadow-montage reconstructions at several assumed inter-pattern distances and picks the most accurate by a metric. |
| 21 | Shadow Montage (rotate patterns) | A shadow-montage variant that rotates patterns while testing several distances. |
| 60 | Compute Correlation Metric | Estimates resolution via the correlation metric of Descloux et al., Nature Methods (2019). |
PtychoBones — multislice for tilted planes
Berk Kücükoglu's PtychoBones package for multislice ptychography of tilted sample planes.
| # | Title | What it does |
|---|---|---|
| 10 | Find Pattern Center | Determines the dimensions/center of the CBED pattern. |
| 50 | Multislice ptychography for tilted sample planes | Runs multislice ptychography on a 4D dataset. |
| 99 | Backup of Berk's Multislice Script | Backup copy of the multislice reconstruction script. |
