Dear Experts,

I am running my polar angle and eccentricity following the freesurfer retinotopy analysis. Saddly, i figured out that my eccentricity script has a shorter cycle compared to the polar angle (38sec vs 40sec pro cycle).

To bypass this error im splitting the analysis and i run the retinotopy separately on polar angle and eccentricity using two different folders and copying the polar angle as eccentricity ( same for eccentricity as polar angle) just in order to run selxavg3-sess. Is this a legal step for the analysis? Furthermore, im getting negative values for masked angles… is this indicating any specific problem?

Many thanks for your help! Giorgio
