| # SAII-CLDM Data | |
| This dataset package supports the official SAII-CLDM open-source implementation. | |
| Payload files: | |
| ```text | |
| Pwavevelocity.mat | |
| marmousi/marmousi_256_train.npz | |
| overthrust/Overthrust_trueimp.mat | |
| prepare_marmousi_256_train.py | |
| vgg.pth | |
| ``` | |
| `Pwavevelocity.mat` is the official Marmousi velocity model file used by the default Stage 1 VQGAN multi-scale training config and the experimental Diffusers VQGAN trainer. | |
| `marmousi_256_train.npz` is derived from the official Marmousi model and contains `256 x 256` log-velocity patches with flip and elastic-deformation augmentations. It is used by Stage 2 training and the experimental Diffusers LDDPM trainer. | |
| `Overthrust_trueimp.mat` is the Overthrust benchmark file used by the evaluation code. | |
| `prepare_marmousi_256_train.py` is a minimal data preparation script documenting the Marmousi-derived training data recipe. It expects `Pwavevelocity.mat` and writes the training `.npz` file. | |
| `vgg.pth` is the LPIPS linear-weight checkpoint used by the VQGAN perceptual loss. The training code copies it to `tmp/vgg.pth` automatically when present in this data directory. | |
| Example `.env` entries for the code repository: | |
| ```bash | |

| MARMousi_NPZ=./data/saii-cldm-data/marmousi/marmousi_256_train.npz | |
| OVERTHRUST_DATA_DIR=./data/saii-cldm-data/overthrust | |
