ROI analyses with fslmeants and featquery not working with fMRIPrep data due to different sizes

[Jacob_Elder]

I got an ROI to work in fslmeants by following the instructions described here of resampling the mask to the the fMRIPrep MNI152NLin2009cAsym space. Featquery still returns an error though, even with the resampled mask.

Is this the best way to get atlas structures to work with fMRIPrep output?

How to transform mask from MNI to native space using fmriprep outputs?

I have a mask of visual cortex created in MNI space. I pre-processed my fMRI data with fmriprep. Now I want to get my mask from MNI to native (functional BOLD) space. How can I make use of the fmriprep outputs to achieve this? Previously, I combined the inverse of the co-registration from anatomical to MNI space and the inverted transformation matrices of the co-registration from functional to anatomical space using FSL’s applywarp. Thanks in advance for your help and please let me know if you n…
