Hi,<br>After doing the retinotopy analysis I find I can&#39;t view the fieldsign with command<br><a href="http://surfer.nmr.mgh.harvard.edu/fswiki/surf-sess" target="_blank">surf-sess</a> -s sessid  -a rtopy -retinotopy fieldsign -flat <br>

(I can view ecc/polar data though.)<br>What is shown is a very dark patch almost invisible. <br><br>I read the entire thread in<br><a href="http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg07329.html" target="_blank">http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg07329.html</a><br clear="all">

I am using the latest build for Mac Intel.&nbsp; I could not find convert_fieldsign.m<br><br>Anybody can help?<br>-- <br>----------------------------------------------------------------<br>Xu Cui<br>
