Bioinformatics

The Bioinformatics Core Facility in the Cancer Research Division at Peter Mac provides a range of services and know-how for data analysis.

Bioinformatics Consulting Core Facility

The aim of the Bioinformatics Core is to provide all levels of bioinformatics support to research laboratories within Peter Mac and, more broadly, within the Victorian Comprehensive Cancer Centre (VCCC). The team of bioinformaticians and postdoctoral scientists at the core work alongside laboratory and clinical researchers and contribute to their experimental design, grant applications and the analysis and publication of genomic and transcriptomic data. Data types analysed by the core include whole-genome and whole-exome sequencing, targeted re-sequencing, radiological images, RNA-sequencing, single-cell RNA sequencing, ChIP-sequencing, NanoString and various types of microarray data. The core also develops and maintains software infrastructure required for bioinformatics processing, including pipelines and cloud provision systems.

Cost recovery

Fees apply to project work. Support to larger projects is available via EFT (part salary) contribution, while smaller projects are charged via a fee-for-service model. The core has a fixed pricing structure, which is updated quarterly, for the most common analysis services. For custom or larger-scale analyses, a quotation will be provided after understanding the requirements and priorities of the project.

Consultation services are available free of charge for Peter Mac staff.

Types of services

Project work

Bioinformatics needs are often unique, and different laboratories may require different levels of support from the core. The team at the Bioinformatics Core can help to analyse project requirements, discuss solutions with the investigators, and subsequently perform the analysis. The team also has extensive experience in generating publication-quality plots that can be used in articles, as well as publishing data as per journal requirements.

Grant applications

Bioinformaticians at the core can contribute to grant applications by generating pilot data, and helping to describe in the application the infrastructure and bioinformatics analyses that are available to support the proposed research.

Consulting

The core can provide consultation on experimental designs and analyses options. For research groups that perform bioinformatics analyses by themselves, the core can share know-how and help troubleshoot as needed.

Methods/software development

Existing tools often fail to answer unique research questions, giving rise to the need for new bioinformatics workflows and/or methods. The team at the Bioinformatics Core has a track record of building robust, highly cited bioinformatics software, and can discuss collaboration opportunities with research groups who are interested.

Deep machine learning

The core is committed to aiding cancer research through the development and application of deep learning (DL) and other machine learning techniques. We have been working on DL projects that involve whole-slide images, radiological images and multi-omics data, and are keen to explore further cancer application areas. 

Pipeline development

Behind the scenes, the core actively develops and maintains analysis pipelines for efficient processing of sequencing data. We also actively collaborate in the maintenance of open-source software for building portable pipelines, and are currently leading the development of Janis. Bioinformatics pipelines are an integral part of high-throughput genomic facilities, and are considered by us as a fundamental software-level infrastructure. The pipelines are available to and have been extensively used by all bioinformaticians at Peter Mac, both within and outside the core.

Partners

The Bioinformatics Core works closely with the Molecular Genomics Core Facility, Research Computing Facility, Papenfuss Lab, and other lab-based bioinformaticians at Peter Mac.
