Mimie - see xlsread for how you can read in the data from the spreadsheet, and in particular, the red and green columns. For your case, you may want to do something like
filename = 'microarrayMimie.xls';
firstPair = xlsread(filename,'E:F');
secondPair = xlsread(filename,'H:I')
where you read in two columns at a time, those in E and F, and those in H and I.
Your next step is that you want to compare to one value. Please elaborate - which elements of the columns are you comparing, and to what?

Mimie - see the find for how you can determine which elements of your vector exceed some threshold. For example, if hData is your column H and you wish to know how many elements exceed 100 then
find(hData>100)
will return all row indices of hData whose element is greater than 100. Now use length to determine how many rows of hData exceed this threshold
length(find(hData>100))
