[Insight-users] Re: how to read analyze files

[Luis Ibanez]

Hi Dhaval,

Regarding your questions on DeformableRegistration4.cxx

1) "How to change the code for 3D images?"

   A) Just edit the file, go to line 106, and replace

         "const unsigned int Dimension = 2;"

      with

         "const unsigned int Dimension = 3;"


   B)  in line 208 add the third component of the initial
       parameters (for the Z axis)

   initialParameters[0] = 0.0;  // Initial offset in mm along X
   initialParameters[1] = 0.0;  // Initial offset in mm along Y
   initialParameters[2] = 0.0;  // Initial offset in mm along Z


               Then recompile...




2)  "How do i change the code in there to read analyze files?"

            You have not done your homework !

from the previous email:

    If you do your homework, there will be no need for
    repeating the same question over and over again.
