• The goal of the ELIXIR proteomics community is to
develop and maintain sustainable proteomics
tools and data resources
• An essential part of the development will also be the
‘FAIRification’ of the resources (i.e. making the
resources FAIR)
• Integrate proteomics bioinformatics activities in
ELIXIR
Overall objectives

• Title: ‘’Mining the proteome: Enabling automated processing and analysis
of large-scale proteomics data”.
• Development of open, reproducible, and robust analysis pipelines for
DDA (Data Dependent Acquisition) approaches.
• Deployment in the EMBL-”Embassy Cloud” (and optionally later other
clouds)
• Connected to PRIDE, bringing analysis closer to the data.
• Who is involved?
• EMBL-EBI (Vizcaíno & Newhouse).
• ELIXIR-DE (Kohlbacher, EKUT, Eisenacher, RUB)
ELIXIR Implementation Study (Feb 2017-June 2018)

ELIXIR Webinar
11 April 2018
Develop exemplary proteomics data analysis workflows and deploy
them in the EMBL-EBI "Embassy Cloud”:
(1) Standard identification workflow
(2) Identification workflow for PTMs
(3) Quantification (label-free/label-based approaches)
(4) Quality Control (to aid data set interpretation/reanalysis
evaluation)
(5) Versions of quantification approaches (including PTMs)

Consolidating data access and provision of robust
analysis pipelines
• Development of free-to-use, scalable, and user-
friendly data analysis pipelines including cloud
deployment
• Cloud-based data analysis pipelines’ appeal
1. Increasingly large datasets
2. Local struggle with the ‘compute task’

Cloud workflow in genomics:
Simplified workflow launcher
• One workflow
• For AWS
• Enabling co-analysis with the larger PanCancer dataset
“Running a >30x whole genome alignment is [...] roughly 4 days
and ~$10 on a single m4.2 xlarge instance.”*

Existing clouds for genomics… one example

Infrastructure as a Service:
• Compute power not necessarily local but remote
• Still from compute centres, but on a larger scale
The ‘service’ is:
• Customer gets infrastructure, but it’s virtualized
• This Abstraction yields better
utilisation and scalability (but...)
• Developer/Customer has to interface with these abstraction layers
What’s a cloud environment?

Analysis pipeline construction

ELIXIR Webinar

We opted for the framework
Features:
• Tool modularisation
• Solutions for data handover between tools with standardised
(PSI) formats
• Adapters for integrating third-party software (Search Engines,
LuciPHOr, FIDO, percolator, etc.)
• Integration into various workflow systems as a basis

Kubernetes & container advantages
• Software in containers
Ø readily usable and well isolated modules
• Resilient system, working in different infrastructure
environments

ELIXIR Webinar
11 April 2018
Summarising the benefits of a cloud based pipeline
• The containerisation of workflow steps makes execution
resource efficient and version aware
• Compute infrastructure can be added dynamically,
infrastructure is setup on-demand (and released after use)
• Bring the analysis to the data

• PRIDE data connection into the cloud is being optimised
• The workflows are deployed into the EMBL-EBI
“Embassy Cloud” Portal and fitted with a dashboard as a
proof of concept.
• Conceptually, these workflows can be deployed in
different cloud infrastructures in the future so they can be
used openly by the wider community.

• Follow-up of the implementation study just mentioned.
• Title: "Extending open proteomics data analysis pipelines in the
cloud: Additional tools and focus on scalability, supporting the

• It will start on August 2018 (1 year):
• Led by ELIXIR-Belgium (Martens).
• Participation of EMBL-EBI (Vizcaíno, Newhouse), ELIXIR-
Germany (Kohlbacher), ELIXIR-France (Bouyssie), ELIXIR-
Spain (Sabidó)
• It will include other tools and additional pipelines (Compomics tools,
QCloud, PROFI tools, etc).
Just approved Implementation Study (2018-2019)

ELIXIR Webinar

• Assigned to the Community (10 ELIXIR nodes involved). It will start
on June 2018 (1 year).
• Title: ”Crowd-sourcing the annotation of public proteomics
datasets to improve data reusability”.
• Apply software developed in the different nodes to improve
automatic annotation pipelines linked to PRIDE (and QC
assessment).
• Improve re-usability of public data.

• Proteomics bioinformatics activities in Europe are
very prominent world-wide
• Analysis infrastructure: work in progress
• Plans for the future:
• Data integration approaches with other ‘omics’
technologies (e.g. genomics, metabolomics, etc).
• Add pipelines for other popular experimental techniques
• Improve data management practises (metadata
annotation, management of clinical data, …)
