Hi Anisha, when you are debugging these things, it's best to go back as
close to the raw data as possible (rather than looking at the final
product on the flat map). Eg, try looking at the eccen and polar
significance maps separately in the volume, then on the surface, then
look at the phase maps in the volume and on the surface, etc.

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
