What would you suggest as the convolutin kernel and the
FWHM for an epi data set with the following parameters:
64X64, xyz 3.75 3.75 7.50 which includes a 5mm gap in
the z direction, TR 2.5, Task, Rest, Task, Rest 10 scans
each, total 40 images. The task consists of showing
stimuli (5 pictures shown at 3s each interspersed with
2s rest intervals). 1.5T magnet
I have tried a 5x5 convolution kernel and a 2X2X2 FWHM
but this shows no difference when compared to
non-smoothed data.
Any information would be extremely helpful!
