Hello,
I have a quick question regarding computing Jacobian using "J" function of
Diffeomap. I registered a smaller volume data to a bigger volume data using
LDDMM and used "J" function to compute Jacobian of this transformation. I
used Kimap,vtk as input file and got the Jacobain values. Instead of giving
a positive Jacobian number, the Jacobian_Kimap,dat gave me negative
Jacobian values, This seems counter-intuitive.
I would appreciate if somebody can guide me if I am doing something wrong
or what is the correct way to compute this Jacobian using LDDMM.
Thanks,
Regards,
Virendra
