# Embedding exploration

This folder contains all the data and code needed to run embedding exploration (Fig. S3). 

### Data download
To help select TF (transcription factor) and Kinase-containing fusions for investigation (Fig. S3a), Supplementary Table 3 from [Salokas et al. 2020](https://doi.org/10.1038/s41598-020-71040-8) was downloaded as a reference of transcription factors and kinases.

- **`data/salokas_2020_tableS3.csv`**: Supplementary Table 3 from [Salokas et al. 2020](https://doi.org/10.1038/s41598-020-71040-8)
- **`data/tf_and_kinase_fusions.csv`**: set of TF::TF and Kinase::Kinase fusion oncoproteins from FusOn-DB database. Curated in `plot.py` 
- **`data/top_genes.csv`**: fusion oncoproteins (and their head and tail components) visualized in Fig. S3b. Sequences for head and tail components were pulled from the best-aligned sequences in `fuson_plm/data/blast/blast_outputs/best_htg_alignments_swissprot_seqs.pkl`

### Plotting

Run `plot.py` to regenerate plots in Figure S3:

```
# Dictionary: key = run name, values = epochs. (use this option if you've trained your own model)
# # Or "FusOn-pLM" to use official model
FUSON_PLM_CKPT= "FusOn-pLM"                                            

# Type of dim reduction
PLOT_UMAP = True
PLOT_TSNE = False

# Overwriting configs
PERMISSION_TO_OVERWRITE = False                     # if False, script will halt if it believes these embeddings have already been made. 
```

To run, use:
```
nohup python plot.py > plot.out 2> plot.err &
```
- All **results** are stored in `embedding_exploration/results/<timestamp>`, where `timestamp` is a unique string encoding the date and time when you started training. 

Below are the FusOn-pLM paper results in `results/final/umap_plots/fuson_plm/best/`:
