Hi,
I need help interpreting the IC maps. I'm confused about the color coding
scheme.
assuming my stimulus paradigm is such: 0001100011000
Instance 1: i get a component with time series 0001100011000. How do i
interpret the red and blue voxels?
Instance 2: i get a component with time series 1110011100111. How do i
interpret the red and blue voxels?
As a separate question;
Using TICA on 10 datasets, i got the task related component. Is it true that
the time series for this component represents the time course of every
activated voxel in the respective spatial map? if so, can i trial average
this time course and validly estimate the shape of the BOLD response in
those voxels?
These ten datasets belong to one paradigm. Can i do a similar analysis on
data from another paradigm(with different stimulus timings) and compare the
effect sizes between the two paradigms? or would i have to run one single
analysis for both?
Thanks!
