[Mristudio-users] FA map problem

[susumu mori]

well, you can always do image-domain interpolation. I'm not sure if it
looks as pretty as the time-domain interpolation by scanners. Some people
say that they are the same thing.

One thing I can comment is, if you will use our atlas-based pipeline for
image quantification, regardless of your image resolution, they are all
resampled to 1x1x1 mm / 181x217x181, as defined by the MNI coordinates. So,
you can just proceed to our MriStudio pipeline without any interpolation.
You feed in your 2.5 mm resolution data and 1mm data will come out.
