## Decription:
-The scripts here support publication in SoftwareX journal [1] to ensure
-reproducibility of the research.
+The scripts here support publication in SoftwareX journal [1] to ensure reproducibility of the research. The scripts linked with data shared at Zenodo.
## Data:
+Data is shared at Zenodo [here](https://doi.org/10.5281/zenodo.2578893)
## Dependencies:
+1. [ASTRA toolbox](https://github.com/astra-toolbox/astra-toolbox): `conda install -c astra-toolbox astra-toolbox`
+2. [TomoRec](https://github.com/dkazanc/TomoRec): `conda install -c dkazanc tomorec`
+3. [Tomophantom](https://github.com/dkazanc/TomoPhantom): `conda install tomophantom -c ccpi`
## Files description:
-
+- `Demo_SimulData_SX.py` - simulates 3D projection data using [Tomophantom](https://github.com/dkazanc/TomoPhantom) software. One can skip this module if the data is taken from [Zenodo](https://doi.org/10.5281/zenodo.2578893)
+- `Demo_SimulData_ParOptimis_SX.py` - runs computationally extensive calculations for optimal regularisation parameters, the result are saved into directory `optim_param`. This script can be also skipped.
+- `Demo_SimulData_Recon_SX.py` - using established regularisation parameters, one runs iterative reconstruction
+- `Demo_RealData_Recon_SX.py` - runs real data reconstructions. Can be quite intense on memory so reduce the size of the reconstructed volume if needed.
