 # HoVpred
 
+## Installation
 
-usage:
-```python
+The environment requires **Linux with CUDA 11.0**.
+
+```bash
+conda env create -f environment.yml
+conda activate hovpred
+```
+
+## Data
+
+The training data originates from NIST and DIPPR databases, which are not freely available. The CSV files in `data/` contain only the molecular identifiers (SMILES) and temperatures, with the enthalpy of vaporization values redacted. As a result, **only the prediction workflow can be reproduced** using the provided pre-trained model weights; model training and cross-validation require access to the original databases.

+
+Prepare a `molecules_to_predict.csv` file with two columns: `smiles` and `temperature`, then run:

+
+**Note:** The enthalpy of vaporization values originating from NIST and DIPPR have been redacted because these databases are not freely redistributable. The CSV files retain SMILES and temperature columns so that the file structure is preserved, but training and cross-validation cannot be run without populating the missing values from the original sources.
