[Rcicr-users] ColMeans question

[Daniel Albohn]

Thanks, Ron. I saw the error after I sent the email. However, after
accounting for it, I still get the same colMeans error. That is, I
seperated the data by base image and tried call the batchGenerateCI2IFC
function again with no success. Do you have any idea what variable this the
colMeans(weighted) is referring to?

To answer your other question, all participants saw both base image faces.

Thanks,
Dan
