Hello,

I am trying to analyze microarray data (E-BUGS-55 and E-BUGS-56) and determine differential expression. I am not sure if you could guide me to some code that can be used for this purpose. The array design information can be found at:

http://www.ebi.ac.uk/arrayexpress/arrays/A-BUGS-20/

I emailed ArrayExpress earlier and they were extremely helpful! The expression values in the data files are in the same order as the Reporter (probe) and gene IDs in the array design files.

I asked this question earlier (Help with microarray analysis (forming cdf files)) and there appears to be an error when conducting the analysis.

I would really appreciate ur help as I am very new to this field and need this analysis as part of a bigger project. Any information or guidance would be greatly appreciated.

Many thanks!

I see that the maintainer of ArrayExpress hasn't responded. You might try contacting him directly:
