About OHBM BrainHack 2021

The event will take place on Sparkle! Every registered participants will receive the credentials via email, if you did not get the email please get in touch!

What is OHBM? OHBM is the Organization for Human Brain Mapping. A Society of scientists dedicated to mapping the brain using all neuroimaging technologies.
What is Brainhack? An event where people get together to learn about open science and to collaborate on projects they’re interested in - it can be on anything!

The OHBM Brainhack is a chance for anyone interested in brains to work collaboratively on common projects (during the hacktrack) and learn about new ideas and tools in open science (during the traintrack).

Brainhacks are not the typical academic conference. Here, attendees can actively take part in the program and learn from each other - sounds something you would like? You can become a part of the event as a volunteer filling this form. Many Brainhack projects might involve coding, but it is not a requirement and you can contribute in most cases even without coding skills.

We look for neuroimagers of all modalities from all over the world at different career stages, and coming from all racial and gender backgrounds who are interested in working together with others to build an open science community. If you're new to the Brainhack community, please join us! If you belong to any minority groups we want to reiterate that we want you here and are excited to have you join us!

NeuroDesk - A scalable and easy to use data analysis environment for reproducible neuroimaging

Time slot : Rising sun

PROJECT DESCRIPTION

Neuroimaging researchers require a diverse collection of bespoke command-line and graphical tools to analyse data and answer research questions. Installing and maintaining a neuroimaging software setup is challenging and often results in un-reproducible environments. Container technology, such as docker or singularity, enables the execution of software on different operating systems and could aid in distributing scientific software. We are developing NeuroDesk, a platform build on container technology for processing and analysing neuroimaging data with the aim to lower the barrier of using various neuroimaging software in a reproducible environment, so that researchers spend less time on setting up and maintaining an analysis environment.

Brain QR Modem - A setup to stream MRI images unidirectionally to the cloud via QR code animations

Time slot : Atlantis

PROJECT DESCRIPTION

Have you ever been annoyed how hard it is to get brain data off the scanner? The fact that scanners usually contain private information about patients and are thus embedded in maximally restrictive clinical cyber-security environments, makes it quite complicated to get access to the data. Especially when visiting collaborative sites. In this Hackathon project, we aim to develop a purely uni-directional (safe) data streaming “hack” to transfer MRI data directly to the cloud by means dynamic QR codes. In the early days of the Internet, modems (modulator-demodulator) were used to (i) convert digital information into audio streams, (ii) transfer them across telephone lines, and (iii) convert them back into the digital domain. Here, we aim to do the same thing with pixel data of MRI scans. However, instead of audio signal we will use machine-readable visual information: QR codes.

Flooding brains: Mesmerizing & relaxing volumetric brain animations

Time slot : Atlantis

PROJECT DESCRIPTION

After 🎆 exploding brains 🎆 in the last year's brainhack, now it is time for animations of a more relaxing sort. I will be mainly using a few LayNii programs that I have been developing for high resolution imaging over the last year (e.g. layers, columns) to generate mesmerizing brain animations. I will focus on using animal brains from one of my favorite projects: https://braincatalogue.org/.

Phys2BIDScoin: Integrating BIDScoin and phys2bids for a user-friendly GUI based BIDS conversion of physiological files

Time slot : Atlantis

PROJECT DESCRIPTION

Phys2bids is a python3 toolkit meant to format physiological files in BIDS. BIDScoin is also a python3 toolkit that is meant to format MRI source files in BIDS. BIDScoin comes with a data discovery routine and a graphical interface to customize the formatting heuristics. The actual data discovery and formatting is done using plugins and the BIDScoin framework itself is agnostic about the source modality. Phys2bids currently lacks data discovery functionality and BIDScoin lacks a formatting backend for physiological data. The goal of this project is to develop the plugin interface between BIDScoin and phys2bids and hence combine their complementary functionality for both projects.

Physiological signal classification challenge

Time slot : Atlantis

PROJECT DESCRIPTION

Phys2bids is a python3 library to format physiological files in BIDS. One of the current development goals is to make phys2bids smarter by implementing an automatic signal classificator. Ideally, given a physiological signal as input, phys2bids should be able to determine the type of the signal (cardiac, respiratory …).

To move forward, this project is structured as a challenge: we provide time-series data of 4 kinds of physiological signals (cardiac, respiratory_chest, O2 and CO2) and the goal will be to collaborate to find robust features that allow discerning between them.

ARTEM-IS web app: working towards an Agreed Reporting Template for EEG Methodology (International Standard)

Time slot : Atlantis+Rising sun

PROJECT DESCRIPTION

The dense data streams and analytical flexibility of electroencephalography (EEG), result in a substantial ‘Garden of Forking Paths’. Recent research (Šoškić et al 2021) shows that most research reports do not contain sufficient detail in their methods to know which path has been taken, hampering reproducibility, replication and meta-science. Our initiative to create an Agreed Reporting Template for an International Standard (ARTEM-IS) includes a draft template designed to make reporting EEG methodology easier and more accurate, by providing fields for researchers to input specific methodological details. Read more about why we need this tool and how you can help to make it better in our (preprint).

The courtois-neuromod physiological data as a use-case for phys2bids

Time slot : Atlantis

PROJECT DESCRIPTION

Phys2bids provides a way to convert physiological recording files to bids format. This brainhack project acts as user testing for the software by applying its workflow to a large-scale dataset. The Courtois Neuromod project is a longitudinal program which collects massive amounts of multimodal data (neuroimaging, peripheral physiologicals signal and eye-tracking) with the same 6 subjects throughout different tasks. We want to apply the phys2bids workflow to the entire physiological signals (electrocardiographic, electrodermal, respiration and pulse) dataset.

Developing collective action campaigns for the neuroimaging community

Time slot : Rising sun

PROJECT DESCRIPTION

Academia is trapped in a collective action problem: we all know there are better ways we could be doing things, but feel pressured to 'play the game' in order to survive a competitive career in science. Historically, collective action problems like this have been solved with collective action, i.e. the mass uptake of new behaviours that aim to further the group's interests. More recently, online conditional pledge platforms (e.g., Kickstarter) have demonstrated that collective action can be organised on a global scale with zero risk to users, serving to cut out middle-men and directly benefit the users themselves. At present, however, this strategy has yet to take hold in academia.

Project Free Our Knowledge (FOK) aims to rectify this by organising collective action in the research community. Using our platform, researchers can pledge to support open science practices, subject to there being a critical mass of support for the proposed behaviour. If the threshold is achieved, everyone who has pledged is contacted and directed to carry out the action together, thus motivating cultural change with minimal risk to individuals.

Nipype 2.0: building new ecosystem around Pydra

Time slot : Atlantis

PROJECT DESCRIPTION

We are creating Nipype 2.0 ecosystem around Pydra package. Pydra is a new dataflow engine, coordinating the movement of data from the output of one computational node to the input of another node. A workflow is represented as a graph, and each node is a Task object, which may be a Python function or an interface to an external tool.

During this hackathon we want to work on the core package, but also prepare converters for Nipype 1.0 interfaces. We are also planning to improve documentation and tutorials.

Pyrda is a lightweight, Py3.7+ dataflow engine for computational graph construction, manipulation, and distributed execution.

Snakebids: Snakemake + BIDS

Time slot : Atlantis

PROJECT DESCRIPTION

Snakemake (url, paper) is a fast-growing open source workflow management system that provides a high level of transparency, reproducibility and adaptability. Despite its wide adoption in the scientific community (>5 new citations per week), Snakemake has not yet had significant uptake in the neuroimaging community.

We have been working on an extension, Snakebids, to ease working with neuroimaging (specifically BIDS) data, and allow the creation of BIDS Apps with Snakemake (e.g. https://github.com/khanlab/hippunfold).

cleanBibImpact: Evaluating the impact of citation diversity statements

Time slot : Atlantis

PROJECT DESCRIPTION

Gender imbalance is a big problem in academic research, and it is even reflected in our citation behavior. Our goal is to assess the 'impact' of the cleanBib tool, which was created to make researchers more aware of this problem. his tool can be used to assess the gender balance of authors in a reference list. Specifically, we want to find papers that cite the cleanBib code/paper/preprint, and see whether those citing papers have better gender balance n their reference lists than papers that do not.

In previous hackathons, we created this figure by manually collecting citation diversity data from papers with citation diversity statements. It shows the relative gender proportions in reference lists of papers with diversity statements (relative to the expected gender proportions).

Opscientia: Decentralised Open Science Stack

Time slot : Atlantis

PROJECT DESCRIPTION

Opscientia is a decentralised autonomous organisation (DAO) aiming to catalyse the pace of scientific discovery — starting with Neuroscience. Today, progress is limited by centralised systems built on outdated infrastructure. This restricts global access to study participation, research funding, scientific collaboration and knowledge creation. Participants also do not retain ownership or control over their own data. Our solution is a decentralised open science stack leveraging blockchain technologies. Global citizens are empowered to take part in studies whilst retaining full ownership and control over their data, and scientists are incentivised to share data and collaborate with their peers. Our solution empowers both citizens and scientists to become the new shareholders of scientific progress.

About the Open-Science Special Interest Group

The OHBM Open Science SIG mission is to advance neuroimaging research by fostering the open sharing of ideas, data, and tools between members of the OHBM community. This will be accomplished by organizing educational events, supporting collaborative initiatives, and providing mentorship to junior researchers.As with previous years, our three main contributions to the OHBM annual meetings are:

  1. organizing a Brainhack to precede the annual meeting
  2. introducing the tools of open science via interactive tutorials as part of the TrainTrack
  3. facilitating collaborative work on a wide range of open science projects

This year the event is happening virtually, and we look forward to this opportunity to reach out to a larger and more diverse audience and to introduce a number of innovations that will enhance virtual collaborations!
