Hi Jason,
Are the grids in your .gpr file all of the same size as specified in the
layout argument? The kooperberg function assumes this and will produce
an error like the one you are getting if they aren't. You might also
have a problem doing print-tip loess normalization on this data if the
layout argument and number of spots on the array don't agree. If this
isn't the problem, perhaps you can send me one of your .gpr files and
I'll take a more careful look. Best wishes,
Matt
