The source for raw data: Source: https://portal.brain-map.org/atlases-and-data/rnaseq/ The Protocol: Gene Expression by Cluster, trimmed means obtained from http://transcriptomic-viewer-downloads.s3-us-west-2.amazonaws.com/human/trimmed-means.zip/ The dataset for the MySQLdatabase was created after normalization using the expression of GAPDH as 100. Latest GeneID, synonyms and descriptions were downloaded (ftp://ftp.ncbi.nih.gov/gene/) and added to each gene symbol of the ABA trimmed means output . The human cortex data was split into either excitatory or inhibitory based on the notation on the cell type nomenclature. The final table was saved as a csv file and uploaded to the MySQL database online which served as the source for searching the expression data using either GeneID, symbol, synonyms or name (description) as the search input. The normalized dataset is also accessible by clicking on the dataset tab on the header. Babru Samal May 2, 2020
