Are you sure the viewing threshold is set correctly for that data? Check out the View->Configure->Overlay dialog box and try changing the values.

Hi Dear FreeSurfers,
I'm using the new version of FreeSurfer to process retinotopic data. I can view the finial results of eccen, polar and fieldsign on the occiptal patch. Now I want to overlay another block designed activations onto the fieldsign patch with file---load overlay--select the corresponding fsig_000.bfloat---select register.dat---OK, but actually no activations appeared on the patch altough the fsig_000.bfloat can be shown on the overlay layer. Would smeone let me know how to overlay the functional activations onto the retinotopic patch?
Thanks in advance!
