10 | 10 | `ff_dual_datasets.py` is a specialized and powerful script within the MIDAS suite designed for the combined analysis of **two separate but related far-field HEDM datasets**. Its primary purpose is to process two datasets independently through the initial stages, spatially map them into a common reference frame, and then perform a single, unified indexing and refinement on the combined data. |

156 | 156 | - **Mapping Fails (`MapDatasets` error):** The most common issue is incorrect offsets. Double-check the signs and values of your `-offset*` arguments. Small errors in offsets can cause the algorithm to fail to find corresponding volumes. Check `dataset_1_analysis/output/map_err.txt` for details. |
157 | 157 | - **Pre-processing Fails:** If one of the initial stages fails, treat it as a standard `ff_MIDAS.py` failure. Check the `output` directory of the corresponding dataset (e.g., `dataset_2_analysis/output/`) to debug issues with peak finding, data conversion, etc. |
