Population-averaged template using GQI reconstructions

[Yuliya Patsyuk]

Dear Frank,

Is it possible to create a population-averaged template using GQI reconstructions? Having partial field-of-view my analysis would benefit from a population-specific template, but it seems that only QSDR reconstruction can be used as input in “P1: Create Population-Averaged Template”: this defeats my purpose as QSDR reconstructions are already warped to a template.

Could you kindly suggest what would be the optimal way to proceed in this case?

Thank you!

Kind regards,
Yuliya Patsyuk

No, because the voxels won't be aligned. QSDR can supports partial view of view but I may need to re revise code and test if it works.

Are you analyzing human data? Which part is the fov located?

Best regards,

Frank

Hi Frank,

It is, indeed, human data. The field-of-view is centered around the brainstem and excludes the parietal cortex partially ("cut" on the top), with some variability among subjects.

Kind regards,

I have existing code to perform partial registration to the template.
If possible, you may upload a sample dataset using website's private
upload link, and I will figure out a solution.

Best regards,
Frank

Hi Frank,

Thank you for your response. I have uploaded the requested data.

Kind regards,

Hi Yuliya,

DSI Studio is updated to support partial FOV with QSDR.

The updated version has a "Partial FOV" at step T2b(2) when you
select QSDR as the method. There you can specify the range of MNI
coordinates to focus on the region you are interested in.

If you have questions about using this function, please let me know.

Best,
Frank
