Dear All,
I have noticed that spm_fmri_spm_ui.m line 407 goes:
LParam = LParam/sqrt(8*log(2));
such that selecting a Gaussian low-pass filter of 4 seconds FWHM
for example, actually results in a value of 1.69 being passed
to spm_filter as the "Gaussian parameter in seconds".
I'm sure there is a simple explanation for this but wish I knew
it.
Yours,
Afraim
