[Insight-users] Why when I use "Gradient Anisotropic Diffusion" and input a time step "0.25" the program shows me a warning that the time step minmum for the image is 0.125?

[Luis Ibanez]

Hi Godspeed,

The error message is indeed misleading.

It says:

   " Minimum stable time step for this image is 0.125"

but it actually means:

"Stable time step for this image must be smaller than 0.125".

So, for a 2D image you should use a time step that is
smaller than 0.125.

We just committed a fix in CVS (for the error message).

    Regards,


          Luis
