Introduction:This set of R tools is an implementation the Subset Prediction from Enrichment Correlation (SPEC) method described in Bolen et al. (BMC Bioinformatics, 2011). This microarray deconvolution technique is designed to provide a simple, easy-to-implement alternative to standard deconvolution techniques, and is designed predict the cellular source for a pre-defined list of genes (i.e. a gene signature) using only data from total PBMCs. SPEC does not rely on the occurrence of cell subset-specific genes in the signature, but rather takes advantage of correlations with subset-specific genes across a set of samples. In addition, SPEC provides tools to compare datasets and calculate p-values for comparisons of interest.
SPEC has been implemented as a set of R scripts, available for download below.
