This is a very neat feature that has been released for Affymetrix microarray gene expression data (only for datasets for which RAW data is available and currently limited to certain platforms):
- All samples from different studies have been normalized with fRMA
- Samples can be “Cherry-Picked” and combined into a “meta-dataset”
- Subsetting is also possible
If samples from various platforms are selected, they will be grouped by platform resulting in one dataset per platform.
