The dataset consists of two data types, seq-FISH data was provided by Zhu et al. (2018), while scRNA-seq data was provided by Tasic et al. (2016).
Data have been retrievedas part of the Hackathon in the Mathematical Frameworks for Integrative Analysis of Emerging Biological DataTypes workshop.
The user can see the available dataset by using the default options

This shows that about 1597 cells match across both modalities / assays.
The scRNA-seq data are accessible with $scRNAseq
