Expression data obtained from the Allen Brain Atlas project [1-4].
get_expression(structure_ids, gene_ids, dataset = "adult")
vector of brain structure IDs, e.g. 'Allen:10208'.
vector of gene identifiers, either Entrez-ID, Ensembl-ID or gene-symbol.
'adult' (default) for the microarray dataset of adult human brains; '5_stages' for RNA-seq expression data of the developing human brain, grouped into 5 developmental stages; 'dev_effect' for a developmental effect score.
Get gene expression in defined brain regions from adult or developing humans, or a developmental effect score for the developing human brain.
Expression data is obtained from the Allen Brain Atlas project [1-4], averaged across donors, and for the developing human brain divided into five major age categories.
The developmental effect score is based on expression data of the developing human brain.
If a requested brain region has no expression data annotated, data from sampled substructures of this region is returned.
Please refer to the
ABAData package vignette for details on the datasets.
A matrix with expression values or developmental effect scores per brain region (rows) and gene (columns).
For expression data from the developing human brain ('5_stages') it is a list with an expression matrix for each of the 5 developmental stages.

## get expression data of six genes in two brain regions ## from the developing human brain, ## each of the five list elements corresponds to an age category get_expression(structure_ids=c('Allen:10657','Allen:10208'), gene_ids=c('ENSG00000168036','ENSG00000157764','ENSG00000182158', 'ENSG00000147889'), dataset='5_stages') ## see the package vignette for more examples
