This repository is for competition in the 2032 Algonauts Challenge.

Please join the MedARC Discord to join our team as a volunteer contributor (join our weekly Monday meetings; see our weekly notes).

Installation instructions

1. Download this repository: git clone https://github.com/MedARC-AI/fMRI-Algonauts-Challenge-2023.git

2. Get our webdataset implementation of the Algonauts Challenge training data. If you are on Stability HPC, it is located in /fsx/proj-medarc/fmri/natural-scenes-dataset/algonauts_data/wds. Otherwise, you need to download the NSD dataset yourself and then use src/algo_webdataset_creation.ipynb to convert it to webdataset format.

3. Run setup.sh to create a conda environment that contains the packages necessary to run our scripts; activate the environment with conda activate mindeye.

cd fMRI-Algonauts-Challenge-2023/src
. setup.sh
