Collaborative AFNI projects at DC code convergence #10
Last week (Sept 10-14), I attended Code convergence in Washington DC, a 5-day hackathon organized by the NIH in collaboration with the AFNI team. Twenty brain imaging researchers and members of the NIH worked collaboratively on improving AFNI and building bridges with other tools.
We had a very productive week! The projects included: an automated testing framework for AFNI | creating machine-readable documentation and interfaces for AFNI through Boutiques | improving support for multi-echo EPI denoising with tedana | NIDM in JSON-LD | and three BIDS projects: understanding modelling of affine matrices in AFNI | refining BIDS model specification in anticipation of AFNI integration | drafting BIDS common transform file format.
I led the NIDM export in AFNI project, to convert AFNI fMRI results into NIDM-compliant archives (or "NIDM packs"). NIDM-Results standardises how fMRI results are represented across neuroimaging software packages. With the NIDASH team, we have developed NIDM exporters for SPM and FSL. As one of the most popular software for fMRI analysis, AFNI was a natural next target.
During this code convergence, I had the chance to work with Rick Reynolds and Justin Rajendra and to get feedback from Gang Chen, three AFNI experts. By the end of the week, we had a first prototype to export an example analysis and upload the resulting NIDM archive to NeuroVault. Future work, will include better integration with AFNI tool, such as leveraging the metadata extracted by the
This week was also the opportunity to hear about other standardisation efforts such as HAWG, a standardised format for human brain atlases.
I would like to thank Dylan Nielson, Adam Thomas, John Lee and Bob Cox for organising this code reunion as well as all the AFNI team!
