Hi Mark,
Got some registration questions...
1. There used to be a description of the transformation matrix in the FAQ, but I can't find it anymore. Can you say which rows/columns refer to translation, rotation, scale, and skew?
2. Given that Mcflirt uses 6 dofs, why do the mat files in prefilted_func_data_mcf.mat look like this? Shouldn't two of the columns/rows have only zeros and ones?
1.000000 0.000000 -0.000824 0.067939
0.000012 0.999895 0.014511 -1.009597
0.000824 -0.014511 0.999894 1.050450
0.000000 0.000000 0.000000 1.000000
3. In avscale, is the forward half transform, the transform to the midpoint from the current volume to the next volume or to the midpoint from the current volume to the reference volume?
4. I want to interpolate the matrix between two endpoints. Can I just interpolate each position in the matrix independently?
thanks!!!
