Thanks for your replies, Jen and Christian. But I want to exclude some
volumes from the middle of the middle of the run. This means they still
need to be there when FEAT calculates the convolution with the hemodynamic
response, whereas if I manipulate the input prior to running FEAT, then
FEAT will have no way of knowing that volumes were removed, so no way of
knowing how to predict the response.
There are several reasons I can think of why one might want to do this:
(1) to exclude volumes in which face/mouth motor tasks are performed (this
is my present goal); (2) to exclude volumes with scanner artifacts; (3) to
exclude volumes where there are saccades, or swallowing, or such, if you
can monitor these.
It would be nice if there was an option to input a file of time points to
be excluded...
best,
Stephen
