to a phase shift of half a cycle for the
"neg" runs compared to the "pos" runs.
However, this problem is solved by changing the code for the "neg" runs to: the
real part equals -cos(phz) and the imaginary part equals sin(phz).
This small change fixed the problem

Hi,
I am currently analyzing some retinotopy data.
For the polar angle stimulus we had both clockwise and counterclockwise stimuli.
Both of them started at the top of the screen (12 o'clock), each run includes 4
full cycles and ends with the last wedge slightly before/after 12o'clock.
We have c
Hi,
I performed a retinotopy analyses with freesurfer using selxavg3-sess.
One of the nii-files that is created with this command is sig.nii.
How is the significance map in sig.nii calculated for retinotopy? which
p-values are used in this calculation?
Thanks!

from the gamma model. It seems that there is more than 2
times differences between these two values. Is it normal, or we need another
scale factor for the fir model?
Thanks for the answers!

My selxavg3-sess analysis was done using the following parameters in the
