Bioinformatics
Cancer research

Background:

Integrative approaches are increasingly used in statistical genomics.
The Cancer Genome Atlas (TCGA) utilizes integrative clustering to identify cancer molecular subtypes.
Realistic datasets are crucial for comparing integrative methods.

Purpose of the Study:

To develop a method for simulating multiple, interrelated omics data types.
To provide realistic datasets for assessing and comparing integrative bioinformatics tools.

Main Methods:

The InterSIM software tool was developed for data simulation.
InterSIM simulates DNA methylation, mRNA gene expression, and protein expression.
Simulations are based on TCGA ovarian cancer study data, capturing realistic correlations.

Main Results:

InterSIM generates realistic, interrelated multi-omics datasets.
These datasets can be used to evaluate the performance of integrative bioinformatics methods.
Example heatmaps demonstrate the application of InterSIM.

Conclusions:

InterSIM facilitates the evaluation and testing of novel integrative bioinformatics methods.
The software enables researchers to use realistic, interrelated genomic datasets.
InterSIM is freely available as an R package from CRAN.
