Dear freesurfer users, Maybe somebody could help me with the following problem: On my retinotopic map I observe extensive blobs with max. values (turquoise and yellow, heat color map), that rather look like noise. However these blobs always appear in the same region, around the anterior portion of the calcarine sulcus in every subject, independent of which paradigm we used for the retinotopy. I use the standard protocol as described for freesurfer/FsFast Individual Retinotopy Analysis on FreeSurferWiki, to analyze my data, however use sfa2fieldsign to display the color map on the inflated surface. If someone has an explanation or a clue why I observe these blobs and/or has suggestions how to prevent them , I'm very thankful. Thanks a lot Best, Elvira
