The analysis is done by creating two regressors: a sine and cosine, both at the stimulation frequency. Each has a regression coefficient computed (ie, a 'beta'). The p-value is computed from an F-test on these two betas.

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!
Thomas
