# CELLEX
CELLEX (CELL-type EXpression-specificity) is a tool for computing cell-type Expression Specificity (ES) profiles. It employs a "wisdom of the crowd"-approach by integrating multiple ES metrics, thus combining complementary cell-type ES profiles, to capture multiple aspects of ES and obtain improved robustness.

# Documentation
The documentation for CELLEX can be accessed in the following ways:
- **[CELLEX Wiki](https://github.com/perslab/CELLEX/wiki)** : main documentation on the usage of CELLEX
- **[CELLEX API docs](https://perslab.github.io/CELLEX/)**: documentation of CELLEX API/functions

([Timshel eLife, 2020](https://elifesciences.org/articles/55851), Appendix)
We are continually updating the documentation for CELLEX. If some information is missing, please submit your request or question via our [issue tracker](https://github.com/perslab/CELLECT/issues).
# Quick start
This brief tutorial showcases the core features of CELLEX.
## TL;DR
```python
import numpy as np
import pandas as pd
import cellex
data = pd.read_csv("./data.csv", index_col=0)
metadata = pd.read_csv("./metadata.csv", index_col=0)
eso = cellex.ESObject(data=data, annotation=metadata, verbose=True)
eso.compute(verbose=True)
eso.results["esmu"].to_csv("mydataset.esmu.csv.gz")
```
## Walkthrough
### Setup
#### Option A: Install the latest release from PyPi
```
pip install cellex
```
#### Option B: Install the development version from this repo
Clone the development repo and install from source using `pip`. The development version may contain bug fixes that have not been released, as well as experimental features.
```
git clone https://github.com/perslab/CELLEX.git --branch develop --single-branch
cd CELLEX
pip install -e .
```
### Import modules
```python
import numpy as np # needed for formatting data for this tutorial
import pandas as pd # needed for formatting data for this tutorial
import cellex
```
### Load input data and metadata
```python
data = pd.read_csv("./data.csv", index_col=0)
metadata = pd.read_csv("./metadata.csv", index_col=0)
```
#### Data format
Data may consist of UMI counts (integer) for each **gene** and **cell**.
| | cell_1 | ... | cell_9 |
|---------------|-----------------------|-----|------------------------|
| gene_x | 0 | ... | 4 |
| ... | ... | ... | ... |
| gene_z | 3 | ... | 1 |
Shape: *m* genes by *n* cells.
#### Metadata format
Metadata should consist of *unique* cell id's and matching annotation (string).
| cell_id | cell_type |
|------------------------|-----------|
| cell_1 | type_A |
| ... | ... |
| cell_9 | type_C |
Shape: *n* cells by 2.
### Create ESObject and compute ESmu
```python
eso = cellex.ESObject(data=data, annotation=metadata, verbose=True)
eso.compute(verbose=True)
```
### View Expression Specificity scores
All results are accessible via the `results` attribute of the `ESObject`.
```python
eso.results["esmu"]
```
### Save result(s)
#### Pro-tip: Using CELLEX with CELLECT
The ESmu scores may be used with **[CELLECT](https://github.com/perslab/CELLECT)**. CELLECT requires that genes are in the *Human Ensembl Gene ID* format. CELLEX provides a simple renaming utility for this purpose:
```python
cellex.utils.mapping.mouse_ens_to_human_ens(eso.results["esmu"], drop_unmapped=True, verbose=True)
```
#### Save ESmu
```python
eso.results["esmu"].to_csv("mydataset.esmu.csv.gz")
```
#### Save all or specific results
```python
eso.save_as_csv(keys=["all"], verbose=True)
```
#### Output format
Output consist of Expression Specificity Weights (float) for each **gene** and **cell-type**. ESmu values lie in the range [0,1].
| | type_A | ... | type_C |
|---------------|-----------------------|-----|------------------------|
| gene_x | 0.0 | ... | 0.9 |
| ... | ... | ... | ... |
| gene_z | 0.1 | ... | 0.2 |
Shape: *m* genes by *x* unique annotations. N.B. a number of genes may be removed during preprocessing.
