Once a transformation matrix has been computed by
'vreg3d', it can be
applied to the 2D anatomical slices acquired during the fMRI experiment (or to a 2D zmap).
The program 'vdotrans' rotates and translates the input data according to the information
contained in the transformation matrix that is specified by '-trans'.
The input image must be either one of the following two types:
- 2D anatomical slices: the 2D anatomical slices that are acquired during the fMRT session.
- 2D zmap: a 2D zmap generated from the 2D fMRT data.
Example:
vdotrans -in file2D.v -out file3D.v
-trans transmatrix.v
The registration accuracy can be checked by
applying the transformation to 2D anatomical slices, and comparing the resulting image with the reference image.
Now click onto several easily identifiable landmarks and check whether they
match in the two images.
Example:
vlview -in /home/newbdb/024/mr024_t1_pl.v file3D.v
If the result is not satisfactory, then redo 'vreg3d' using different parameters.
