Expression data obtained from the Allen Brain Atlas project [1-4].
vector of brain structure ids, e.g. 'Allen:10208'.
vector of gene identifiers, either Entrez-ID, Ensembl-ID or HGNC-symbol. If not defined, genes from previous enrichment analysis with
'adult' 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. If not defined, dataset from last enrichment analysis with
logical indicating whether expression from background genes should be included. Only used when
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
dataset are not specified, the genes and dataset from the last enrichment analysis with
aba_enrich are used, since it may be a common case to first run the enrichment analysis and then look at the expression data. 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.
