Hi,

I am trying to get depth/resolution (in bit 12,14,16,20) from several microarray gene expression platforms. Is there any simple way to do it with R ? I have been trying to find detail on ncbi or manufacturers website. I am also using boxplot of log2 transform to guess but I am looking for something more robust.

Best, SK

What exactly do you mean by depth/resolution in bits?

A lots of platform are 16 bits per pixel resolution images, providing color depth of 65536 levels like GPL570 but it is not always the same for example GPL6480 is 20 bits per pixel and it is important to me in the context of meta analysis

Ah, how many bits the camera uses when it encodes the images. I have no clue and I suspect that that's machine dependent, rather than chip-dependent.
