maigesPreRaw, maigesRaw and
maiges containing a piece of the dataset that was
analysed by the MAIGES (http://www.maiges.org/) and published at
Cancer Research (see the reference below). In this dataset we
evaluated the profiles of expression for 72 gastro-esophagical
samples. Were used cDNA microarrays with slides containing 4800 spots
representing approximately 4400 unique genes. The original dataset was
composed from 86 samples with dye swap (what makes 172 chips). The
dataset available here contain a subgroup of 20 samples (40 chips) and
500 spots (486 unique genes). The objects available are:
- gastro: maigesPreRaw class containing the raw dataset.
- gastro.raw: maigesRaw class containing the
dataset ready for filtration and normalization.
- gastro.raw2: same to the above, after filtration.
- gastro.norm: maiges containing the normalized
data.
- gastro.summ: same to the above, after summary of replicates.
