Dear Serena,
The problem is nothing to do with your EV file
but due instead to the phase setting for the
Double-Gamma HRF. It seems that Phase
values of -1.25 (= -TR/2) or less cause this
problem, which looks like a bug in FEAT.
In the meantime you could either use a
different convolution (e.g. Gamma) or a
different Phase value. Is there any reason
you are trying to use such a large value?
We will hopefully be able to fix this and get
it patched soon, but I cannot be sure when.
All the best,
Mark
