Hi Bruce,
After unpacking the data, I simply run the selxavg command below and allow it to do the automatic pre-processing.
selxavg3-sess -s Subjects/myla -a LOC_fsaverage_5p3.rh
The analysis was generated with the following command:
mkanalysis-sess -analysis LOC_fsaverage_5p3.rh -surface fsaverage rh -fwhm 5 -paradigm LOC.par -event-related -polyfit 1 -gammafit 2.25 1.25 -mcextreg -TR 2.000 -nconditions 2 -refeventdur 16 -per-run -force -fsd bold
After fixing up the registration I saved the registration file under :Subjects/myla/bold/014/register.dof6.dat" and ran bbregister for all the runs within the subject folder as below.
bbregister --mov Subjects/myla/bold/015/f.nii --reg Subjects/myla/bold/015/register.dof6.dat --init-reg Subjects/myla/bold/014/register.dof6.dat --bold
I then ran the selxavg3-sess again.
Let me know if you need any more information to help.
Thanks! Cesar

Hi Cesar
what command lines did you run to register and sample?

Hello freesurfer experts,
The functional overlay for one of our subjects looks like the image attached. You'll notice the "holes" on the overlay that have a value of 0. I'm trying to get ride of these as I expect (as with other subjects) to have values for these vertices that are not 0. Myself and a colleague have tried improving the registration as much as we see possible, but the problem remains. Any tips on how to correct this issue would be greatly appreciated.
Thanks in advance for your help! [cleardot.gif] Cesar Echavarria Research AssistantMartinos Center for Biomedical Imaging, Harvard-MGH
