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! Cesar Echavarria Research Assistant Martinos Center for Biomedical Imaging, Harvard-MGH Brain & Cognitive Sciences | MIT 2012
Hi Cesar
what command lines did you run to register and sample?

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

It could be that the brain mask is too aggressive. Try looking at Subjects/myla/bold/RRR/masks/brain.nii.gz

I used the command below to check the brain mask relative to the subject's anatomy:
tkmedit myla_anat orig.mgz -over Subjects/myla/bold/masks/brain.nii.gz
The mask looked fine in that no portion of the brain appeared to lie outside the mask.

Have you checked the registration? If so, are you sure that the activation is exactly 0? Also, look at cortex.label to check whether somehow those vertices were not labeled.

Hi Doug,
Me and Shahin have looked at the registration and it looks fine. I know the activation is 0 because when I click on those vertices it tells me the tksconcat.nii value is "**0.000000**". I looked at the cortex.label file and found the 0-valued vertices within the file. We have scanned the same subject for different experiments but it is only for this session that we find the problem. Let me know if there's anything else we can check.
Thanks! Cesar

I looked at the surface mask and it seems those 0-valued vertices are 0-valued in the mask as well (image attached). Is there a way to correct this? To reiterate we have already tried revising the registration.

Hi Doug,
Me and Shahin have looked at the registration and it looks fine. I know the activation is 0 because when I click on those vertices it tells me the tksconcat.nii value is "**0.000000**". I looked at the cortex.label file and found the 0-valued vertices within the file. We have scanned the same subject for different experiments but it is only for this session that we find the problem. Let me know if there's anything else we can check.
Thanks! Cesar

To add to my previous e-mail, it seems the surface masks differ from run to run. The run whose registration we revised manually seems to have no problem. We then use the registration from this run as the initial point for the registration of subsequent runs. These later runs do show those "holes" on the surface mask. Is there anything we can try with the bbregister command to prevent it from getting stuck in local minima or the like?
Thanks
Cesar
