Robust multi-array average (RMA) is a
method for deriving expression
measurements from the probe level data
contained in an Affymetrix CEL file.
GeneSifter users have the option to
perform RMA or GC-RMA during the
upload of CEL files. The normalized data
is saved in the user’s account for further
analysis.
1. Locate the Affymetrix .CEL files
you want to load on your local
computer.
2. All the files to be uploaded and
transformed using RMA need to
be compressed into a single ZIP
file for upload.
3. Select Upload Tools from the
Control Panel.
4. Click on Run Advanced
Upload Methods to begin.
