The MERFISH spatial transcriptomics dataset (MERFISH-C57BL6J-638850) was mapped to the whole mouse brain taxonomy (WMB-taxonomy) using a hierarchical correlation method. To further integrate the transcriptomics and spatial profiles of each cell type, 10Xv3 expression was projected or imputed into the MERFISH space. The basic idea is to compute the k-nearest neighbors (KNNs) among the 10Xv3 cells for each MERFISH cell and use the average expression of these neighbors for each gene as the imputed values. Imputed expression values were generated for 8,460 marker genes. Further details can be found in the methods section of Yao et. al.
