Hello,
I am trying to create a Jacobian of the field using --jout option in fnirt command.
What i observed was that the Jacobian maps generated by fnirt' ing images A-->B and B-->A are not inverse consistent.
For example: when i choose a random voxel on the Jacobian map, i see that the value for that particular voxel in both cases (A-->B and B-->A) are greater than 1. Which means that the same voxel is expanding in both trials.
Is there a way to make it inverse consistent, so that i see expansion in one direction (A-->B) and contraction in the opposite direction(B-->A)?
