# Overview

IOBR is the acronym for Immuno-Oncology Biological Research to perform multi-omics immuno-oncology biological research to decipher tumour microenvironment and signatures for clinical translation.

# Module Introduction

IOBR encompasses six functional modules:

- Transcriptome data prepare module : pre-procession of transcriptome data, as well as pertinent batch statistical analyses;
- TME deconvolution and signature estimation module : estimation of signature scores and identification of phenotype relevant signatures, along with decoding immune contexture;
- TME interaction module : clustering TME characteristics and analyzing receptor-ligand interactions;
- Genome and TME interaction module : analysis of signature associated mutations;
- TME data visualization and Statistical analysis module : visual representation and statistical examination of TME data;
- TME modeling module : fast model construction and the assessment of model performance.

# Methodology

IOBR integrates eight open-source deconvolution methodologies: CIBERSORT , ESTIMATE , quanTIseq , TIMER , IPS , MCPCounter , xCell and EPIC . In addition, 323 published signature gene sets have been collected by IOBR covering tumour microenvironment , tumour metabolism , m6A , exosomes , microsatellite instability and tertiary lymphoid structure. IOBR has used three computational methods to calculate the signature score, including PCA , z-score and ssGSEA.

# Visualization

IOBR integrates visualization function, including boxplots , heatmaps , percentage bar charts , scatter plots , KM plot , PCA plot etc.
