How to know if it is 'one-color' or 'two-color' microarray?

[r4bioinf]

Hello members,

I would like to know how to check if the studied microarray (such as GSE13105 from GEO) is one-color or two-color array?

For example, I can obtain the raw data (e.g., A.CEL), if there is a way to know the A.CEL is one-color or two-color microarray?

Thanks,

Kevin

.CEL is affymetrix one-color array. If you look GSE13105 description carefully, you would see Channel1 (Cy3) and Channel2 (Cy5), clearly two-color array.
