    Hello, I'm performing simulation on head models reconstructed from MRI scans and I integrate the white matter anisotropy obtained from DTI as shown in the jupiter notebook tutorial. I'm interested in extracting electric field in small boxes, is there a way to extract also FA and eigen vector in just those boxes?

      This question is quite old. Maybe you found a solution?

      Otherwise I guess you could use one of these options:

      • you can crop the field, e.g. via the bounding box (or the extent if you have an E-field on a rectilinear grid)
      • you could use the interpolation filter: define your little box grids, and interpolate from the field sensor field to your box grids
      • you could define small field sensors in the simulation setup (not sure it is scalable to hundreds of sensors)
