Dear all,
I'm trying to display the fieldsign map. I used standard
rotating-wedge and expanding-ring paradigm, and I followed the steps
described in FsFastIndividualRetinotopy Analysis.
I'm running freesurfer on Ubuntu 14.04.
Polar angle and eccentricity map look good but I can't properly
display the fieldsign map as an alternation of two colours. I attached
a screen-shot as example.
Any suggestion?
Thanks for the help!
Francesca
The command line is;
tksurfer-sess -a rtopy.DM.lh -s SUBJ01 -fieldsign
and that's the output:
shalim-ubuntu:/usr/local/freesurfer/fsfast/MeytalRetinotopy>
tksurfer-sess -a rtopy.DM.lh -s SUBJ01 -fieldsign
