Confusion related to a term probe-by-background interaction I just found out that it is just the product of the probe values and the background values. However, they have mentioned probe-by-background term(paired t-test P-value=7,5*10^-5, paired Mann-Whitney test P-value=5.2*10^-5). What is meant by this? |

Confusion related to a term probe-by-background interaction I am wondering if they used the ttest values for the interaction term? |

Confusion related to a term probe-by-background interaction I didn't understand how it is calculated. I mean probes are the original probes. Background are formed by applying PCA and taking the best 6. I didn't understand how this interaction term is calculated. How do I know which background a probe is in. Also I didn't get why it is called background. I mean they have just applied PCA to capture the decorrelated basis which capture the most variance. Why is it called background? |

Confusion related to gene expression I need to get the gene id for the corresponding probe it. For that I need the CDF file. So I was actually wondering where I can get them? |

Confusion related to gene expression Thanks I will try that. However it looks like I will need some CDF files as well. Where can I get them? In particular I need the CDF files for chip type HG-U133_Plus_2 and HG-U133A. Any suggestions? I looked a couple of places but looks like I have to pay for it. It was supposed to be free I guess |

Confusion related to gene expression @rg255. Also I didn't get the link you said this website. I didn't find the link attached |

Confusion related to gene expression @rg255. I didn't get how the processed data is generated. As you can see here ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE7904 there are two data sets. One is raw CEL files and the other is Series Matrix File(s). How is this processed data generated. Also if I look at the number of rows. In the case of Cel files, the number of probes is huge 1354896. But when I look at the series matrix data it is around 50000. I didn't get it. Any suggestions? |
