Re: [Freesurfer] two vol fields for retinotopic analysis?

I don't know what you mean by 3D coordinates or a 1d array of corresponding phase values. In any case, use the mri.vol. This should be in voxel-for-voxel correspondence with your input data.

Dear freesurfer experts:

I noticed that there are two 'vol' fields when I use MRIread.

1. mri.vol
2. mri.analyzehdr.vol

My question is:

I have two arrays, one with 3D coordinates and a second 1 dimensional array with corresponding phase values.

Which 'vol' field do I put the 3D coordinates in and which do I put the phase values in?

Many thanks!
