[Freesurfer] functional overlay onto the occiptal patch with fieldsign

2006-10-04 Thread Lei . Zhang
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!

Lei

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.
