Analysing RNA seq data

Question

[windsur]

Hello all! I am new analysing RNA-seq data. They give me a directory containing: 1 normal sample and 15 tumor samples, each one has its cel file, exp file, and dcl file. They ask me to do a reanalysis, but I think I need more information, like the plataform (e.g. affimetrix) and the annotation database. Am I correct? How should I proced to do the analysis? I have followed this tutorial, but I do not have all the data here. Is there a way to get the probe annotation or is something that they should give me?

Thanks!!

My CEL files look like that:

You should get the GPL number

This is the first time that I am trying to analyse a microarray. Do you know if I can get the GPL from another source? thanks!

Usually you can get the GPL form where the data from，you should ask the one who give you the data or the company that performed the sequencing.
