Dear all,
I want to ask you some questions about melodic ICA.
I am working on drug response data on anesthetic monkeys. Since we don't know the exact response curve of the drug effect on monkeys, ICA must be a perfect method for our exploratory purpose. Furthermore, as the design (onset time of drug injection) are the same across the monkeys, tensor ICA is preferred, right? Based on the components from tensor ICA, we might get several components related to the drug effect. If I go the "report" folder, I can find time courses of each component with files named begin with t*.txt. For each component, is the first column the time course for the group component and are the other columns for all individual subjects? How can we get the individual IC maps? Using dual regression approach? What do the reconstructed IC maps mean? Beta values (is it equal to response amplitude?) for drug activation? What maps should we used for further statistic analysis?
Thanks a lot in advance!
