[Freesurfer] Retinotopy and MT+ localization analysis help

To whom it may concern,

I am a beginner at FreeSurfer and using it in my senior biomedical design project at Boston University. I have performed retinotopy and MT+ localization before on a previous subject and obtained good results. However, I have carried out retinotopy and MT+ analysis on another subject using the same commands and have not obtained significant results. I have tried the analysis using motion corrected and motion uncorrected data, and have obtained bad results both times. I have attached the fieldsign image above obtained from the retinotopy analysis. Please let me know, if you would like to see the polar, eccentricity or MT+ images as well. I appreciate your time and concern

Thank You, Anisha
