Purpose:

This WAIR command is used to obtain the Cluster Group Classification (CGC) and the induced warp ranking having a family of warps applied to a group of data sets.

The CGC Classification of family of image-registration techniques is determined based on the warp performance on a group of data sets. You need to have executed "WT_IWT" and "wave_space_varThresh" first before you call "CGC_WTC", if wavelet-space analysis is to be done!

Usage:

CGC_WTC Num_Dim x_1_Dim_Size [ [x_k_Dim_Size] ] Num_Data_Sets Num_Warps [[Data_1_Warp_k]] [[Data_2_Warp_k]] ... [[Data_n_Warp_k]] results_Data_CGC.text

where the following definitions are used:
Num_Dim
the number of dimensions of the data set
x_1_Dim_Size
the the size of the first (fastest varying index) dimension of the data. Remember, all dimension sizes need to be powers of 2
x_k_Dim_Size
the the size of the k-th dimension of the data
Num_Data_Sets
the number of data sets in the group
Num_Warps
the number of warps involved in the study
Data_1_Warp_k
data "l" resliced using warp "k", 1<=l<=Num_Data, 1<=k<=Num_Warps
results_Data_CGC.text
file that will contain the output of the CGC analysis

Examples:

./CGC_WTC 3 256 256 128 5 3 ./WTmri1_Wp1.img ./WTmri1_WP2.img ./WTmri1_Wp3.img ./WTmri2_Wp1.img ./WTmri2_Wp2.img ./WTmri2_Wp3.img ./WTmri3_Wp1.img ./WTmri3_Wp2.img ./WTmri3_Wp3.img ./WTmri4_Wp1.img ./WTmri4_Wp2.img ./WTmri4_Wp3.img ./WTmri5_Wp1.img ./WTmri5_Wp2.img ./WTmri5_Wp3.img ./resultsMRI_CGC.text

This command will quantify, using CGC, the performance of 3 warps (Wp1, Wp2, Wp3) applied to a group of 5 (thresholded) stereotactic (3D) WT's of the images of size 256*256*128 (mri1, ..., mri5). The results of the CGC analysis will be saved in the output file "resultsMRI_CGC.text", in the current directory. Also look at the batch file "batch_CGC". Note that the above example represents a single command-line.
