multi_tissue: data objects for multi-tissues mixing samples
Description
a list containing:
1) x.data:a data frame providing the RPKM of nine mixing samples.
2) x.signatures: a data frame providing the expression values from pure brain, muscle, lung, liver and heart samples.
3) x.signatures.filtered: a data frame providing the expression values from pure brain, muscle, lung, liver and heart samples after filtering.
4) x.signatures.filtered.optimal: a data frame providing the expression values from pure brain, muscle, lung, liver and heart samples used for the example in DeconRNA-Seq.
5)fraction: a data frame providing the fractions from 5 tissues in the mixing samples
Format
A list
1) a matrix with all the genes' expression in the mixing samples: the first two columns are corresponding to the RefSeq accession numbers and gene symbols 2) a martix whose rows are gene symbols and columns are RPKM expressions from pure tissues. 3) a martix whose rows are gene symbols and columns are RPKM expressions from pure tissues: the genes with RPKM less than 200 within any of the five tissues have been filtered. 4) a martix whose rows are gene symbols and columns are RPKM expressions from pure tissues: based on the filtered signature matrix, the optimal number of genes have been selected for the deconvolution according to the condition numbers 5) a martix whose rows are mixing samples' name and columns are fractions from pure tissues including brain, muscle, lung, liver and heart
