Hi,<br> <br>I have faced a problem using ROI-based, fcseed-config and fcseed-sess<br><br>I used either: <br><br>fcseed-config -roi /cluster/tootell/pitcairn/1/shahin/good_subjects_anat/atou_anat/label/rh.V1.label -fcname mean.R_V1.dat -fsd bold -mean -cfg mean.R_V1.config <br>
<br>OR: <br><br>fcseed-config -roi 
/cluster/tootell/pitcairn/1/shahin/good_subjects_anat/fsaverage/label/rh.V1.label
 -fcname mean.R_V1.dat -fsd bold -mean -cfg mean.R_V1.config <br><br>to generated the mean.R_V1.config file for right V1 area (ROI for V1 is generated automatically and I have not changed it). Then I use below command to generate mean.R_V1.dat for the session of interest (e.g. atou)<br>
<br>fcseed-sess -s atou -cfg mean.R_V1.config -make-mask  <br><br>but I just get a &quot;if: Expression Syntax.&quot; message and the expected dat file is not generated.<br><br>Do you have any idea what is wrong? Any help will be highly appreciated.<br clear="all">
