[Freesurfer] more on fieldsign problems-

Dear all, I've been having issues with my fieldsign images all I get are speckles. I did the following and did not get any errors:

1) ran recon-all -all 2) cut and saved occipital patches (rh.occip.patch.3d) from inflated surface 3) ran mris_flatten -w 0 distances 20 7 rh.occip.patch.3d rh.occip.patch.flat 4)mkanalysis-sess -rtopy.self.rh -surface self rh -TR 2 -retinotopy 48 paradigm rtopy.par -nskip 4 fwhm 0 5) selxavg3-sess -a rtopy.self.rh -s sj09 6) fieldsign-sess -a rtopy.self.rh -occip -s sj09

When I looked at the fieldsign map using: 7) tksurfer-sess -a rtopy.self.rh -s sj09 -fieldsign

all I got were blue and red speckles. The polar and eccentricity maps seemed ok.

Any help would be great.
