Hi Bianca, it is not currently possible to this since it expects to have one cycle duration. You can analyze them separately, then create a field sign map outside of the regular stream.

Dear Freesurfers,
When I only had 3 runs of polar angle data for retinotopic mapping, I used for example this command to make the analysis:
mkanalysis-sess -a rtopy.self.lh -surface self lh -TR 2 -retinotopy 12 -paradigm rtopy.par -fwhm 5 -fsd bold
For some new subjects I have 3 runs of polar angle mapping and 3 runs of eccentricity mapping, with different parameters (cycle duration differs). Is it possible to analyse polar angle and eccentricity in one go? If so, what do I put under the -retinotopy flag?
Thanks, Bianca
