Dear minisharmaa,
You are correct in what you state above. The most straightforward solution to the problem of different sized ROIs is using rMEA (R-package), where you can apply the z-transformation of your raw MEA-data (withoug centering the data).
e.g. –>
## rescale with standard deviation
mea_scaled = MEAscale(mea_raw, scale = “sd”, center = F, removeNA = TRUE)

For more details, see:
