Hi list,
I'm using Siena on a series of MRIs. I might be interested in these options:
-t <t>: ignore from t (mm) upwards in MNI152/Talairach space - if you
need to ignore the top part of the head (e.g. if some subjects have
the top missing and you need consistency across subjects)
-b <b>: ignore from b (mm) downwards in MNI152/Talairach space;
I'd like to know if there is a way to calculate automatically an
optimal value to supply to either of those options based on a series
of MRIs; or, if not an automatic method, at least a convenient one,
short of checking each and every MRI and manually deciding a value. I
can't find anything on the internet.
I'm a bit wary of doing it manually since it seems potentially prone
to errors (besides being time-consuming if one has many MRIs).
Thanks for your time,
Lorenzo
