[…] was analyzed using genechip® human transcriptome array 2.0 microarrays (affymetrix; thermo fisher scientific, inc.) according to the manufacturer's protocol. the raw data were analyzed by using the affy package (version 1.55.0; affymetrix; thermo fisher scientific, inc.) in r (10). the robust multi-array average method was employed to corrects probe intensity values and the microarray data […]

[…] identify potential drug targets for ras. we firstly downloaded the gene microarray datasets with the accession number of gse37265 from geo and performed robust multi-array (rma) normalization with affy r programming package. secondly, differential expression genes (degs) in ras samples compared with control samples were identified based on limma package. enriched gene ontology (go) terms […]

[…] medical campus microarray and sequencing resource. cel files were normalized to produce gene-level expression values using the implementation of the robust multiarray average (rma) [32] in the affy package (version 1.36.1)[33] included within in the bioconductor software suite (version 2.11) and an entrez gene-specific probeset mapping (version 17.0.0) from the molecular and behavioral […]

[…] meta-analyses were conducted to increase the statistical significance and to minimize the noise intrinsic to gene expression measurements. microarray datasets were normalized using frma61 from the r affy package67. when multiple probes matched the same gene symbol, probes presenting the greatest inter-quartile range were selected. only genes present in all the selected platforms were considered […]

[…] and 14 osteosarcoma specimens, were available based on the affymetrix human genome u133a array., we converted the probe-level data in cel files into expression measures using the rma function of the affy package in r [14]. then, the r/bioconductor notes package of the microarray data platform was used to map probe sets to genes. for each sample, the expression values of all probes for a given […]
