DeSide 1.3.3

A unified DEep-learning and SIngle-cell based DEconvolution method for solid tumors

DeSide: Cellular Deconvolution of Bulk RNA-seq

What is DeSide?

DeSide is a DEep-learning and SIngle-cell based DEconvolution method for solid tumors, which can be used to infer cellular proportions of different cell types from bulk RNA-seq data.

DeSide consists of the following four parts (see figure below):

• DNN Model
• Single Cell Dataset Integration
• Cell Proportion Generation
• Bulk Tumor Synthesis

In this repository, we provide the code for implementing these four parts and visualizing the results.

Requirements

DeSide requires Python 3.8 or higher. It has been tested on Linux and MacOS, but should work on Windows as well.

• tensorflow>=2.11.1
• scikit-learn==0.24.2
• anndata>=0.8.0
• scanpy==1.8.0
• umap-learn==0.5.1
• pandas==1.5.3
• numpy>=1.22
• matplotlib
• seaborn>=0.11.2
• bbknn==1.5.1
• SciencePlots
• matplotlib<3.7

Installation

pip should work out of the box:

# creating a virtual environment is recommended
conda create -n deside python=3.8
conda activate deside
# update pip
python3 -m pip install --upgrade pip
# install deside
pip install deside

Usage Examples

Usage examples can be found: DeSide_mini_example

Three examples are provided:

• Using pre-trained model
• Training a model from scratch
• Generating a synthetic dataset

Example 1 can now be run with one function call after import:

import deside

deside.predict_with_pretrained_model(
    input_file="path/xx_TPM.csv",
    output_file_path="./results/y_pred.csv"
)

This helper expects the same local assets used in the mini example:

• ./DeSide_model/ for the pre-trained model files
• ./datasets/gene_set/ for the pathway .gmt files

By default, missing Example 1 assets will be downloaded automatically into those folders (with explicit download logs). To disable auto-download, pass auto_download=False.

You can also run Example 1 from this repository as a script:

python examples/example1_pretrained_model.py \
  --input-file path/xx_TPM.csv \
  --output-file ./results/y_pred.csv

Documentation

For all detailed documentation, please check https://deside.readthedocs.io/. The documentation will demonstrate the usage of DeSide from the following aspects:

• Installation in a virtual environment
• Usage examples
• Datasets used in DeSide
• Functions and classes in DeSide

Changelog

See docs/changelog.md for the full change history.

• v1.3.3 (June 16, 2026): add a one-call pre-trained model API, automatic downloads for Example 1 assets, and a runnable Example 1 script.
