Hello, I have a basic question regarding retinatopy analysis. In the paradigm files we specify whether the run was mapping eccentricity or polar angle stimulus, and we specify the number of cycles in mkanalysis. Don't we need to be more specific about the stimulus, i.e. how many wedges trace one cycle or the duration of each wedge?
Thanks,
It can determine that once it has loaded in the functional volume as it will have the TR and the number of time points at that time.

Hi, I had a question regarding the labels listed in FreesurferColorsLUT.txt. Does any of the data Freesurfer outputs contain Labels 400-409 (corresponding to various Brodmann's Areas)? I've never seen those labels used in the publicly-released version, but wanted to verify since a coworker was specifically asking about them.
Thanks,

Hi Aaron,
if you look on the wiki there's an online preprint of a forthcoming Cerebral Cortex paper on this. We're happy to distribute the labels and were going to include them in the next release I think in any case.
