Affy CEL files for Tilescope

I was trying to use the TILESCOPE program for analyzing Arabidopsis tiling array data, but was unsuccessful. First of all, the .CEL files were not uploaded as it always showed that the file extension is incorrect. I was wondering if tilescope does not support .CEL files? But in the sample you have provided, there is an option for the same but that never appears on my computer (I am using a Mac machine). Do you think I should be downloading the program in order to solve it?

Tilescope does support CEL files. It is possible that it doesn't recognize your extension if it is not in all lower case. Since it is a web program, it doesn't matter if you're using a Mac or PC or any other OS as long as you're using a browser.
