Dear all,
Is it valid to do PPI or DCM on multi-shots images? I have some fMRI data which
were acquired with a 2-shots spiral approach. I would like to do connectivity
analysis between the motor cortex and the insular cortex on this data set but
worry about the timing of multi-shots data may not be as accurate as that of
single shot data. So, can we use PPI or DCM to work with this 2-shots data? or
is there any alternative approach for connectivity analysis? Any suggestion is
highly appreciated.
Many thanks,
savio
