GPL200.arrays.1_to_500: Data: A compendium of C. elegans Affymetrix microarry data

In MPCary/DEXDATA.Celegans: C. elegans data files for DEXICA analysis

Description

A 22,625 x 1386 matrix containing Affymetrix microarray data gathered from the GEO database for the model orgnaism C. elegans. The matrix was preprared by running the rma algorithm on all of the arrays from a particular experiment (arrays with the same GSE ID in GEO), followed by bias correction using the biasCorrection algorithm. Between-array quantile normalization was not performed, as this tended to degrade the performance of the fastICA algorithm.

Usage

GPL200.arrays.1_to_500

GPL200.arrays.501_to_1000

GPL200.arrays.1001_to_1386

Format

A numeric matrix with probesets in rows and arrays in columns.

Details

The original matrix has been split into three pieces in order to comply with GitHub file size limits; users should combine the three matrices using cbind to work with the full matrix (see examples).

Examples

## Not run: 
# Combine pieces into single matrix
x = cbind(GPL200.arrays.1_to_500, GPL200.arrays.501_to_1000,
  GPL200.arrays.1001_to_1386)
