Dear. Freesurfer experts.

Hi. I'm trying retinotopy analysis using freesurfer version 5.3.0.

I'm having a problem when running selxavg3-sess...

Could you please help me with this issue?

I have 3 runs under bold_retino and all 3 scans have the same dimension..

The command line that I entered are:

mkanalysis-sess -analysis retino.lh -TR 2 -paradigm para.para -event-related -funcstem fmcpr.sm0.self.lh -nconditions 4 -timewindow 34 -inorm -gammafit 2.25 1.25 -polyfit 2 -nuisreg mcprextreg 3 -force -fsd bold_retino -per-run -surface self lh -refeventdur 8

mkcontrast-sess -analysis retino.lh -contrast HorVer -a 1 -c 2 mkcontrast-sess -analysis retino.lh -contrast UpperLower -a 3 -c 4

preproc-sess -s $SUBJECT -df sessdirfile -fsd bold_retino -per-run -force -surface self lhrh -fwhm 0

selxavg3-sess -s $SUBJECT -analysis retino.lh -df sessdirfile

Then I get the error:

I'm getting confused what's causing this issue.

Please help!

I appreciate your advice in advance.

Thanks, Ji Won
