Purpose:

This WAIR command is used to obtain the compressed wavelet-space triangle warp classification for single or multiple data. The induced warp ranking reflects various GS's (gold-standards) along the line connecting the data to the target in compressed wavelet space. You need to have executed "WT_IWT" and "wave_space_varThresh" first before you call "triangleWTC"!

Usage:

triangleWTC Num_Dim x_1_Dim_Size [ [x_k_Dim_Size] ] Num_Data_Sets Num_Warps Target Data_1 [[Data_1_Warp_k]] Data_2 [[Data_2_Warp_k]] ... Data_n [[Data_n_Warp_k]] results_Data_Tri.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

Target

the name of the data-file used as a target of the warps

Data_l

the name of the l-th original data set (prior to warping) 1<=l<=n

Data_1_Warp_k

data "l" resliced using warp "k", 1<=l<=Num_Data, 1<=k<=Num_Warps

results_Data_Tri.text

file that will contain the output of the wavelet space triangle warp ranking

Examples:

./triangleWTC 4 128 128 256 512 5 3 ./WTtarget.img ./WTpet1.img ./WTpet1_Wp1.img ./WTpet1_Wp2.img ./WTpet1_Wp3.img ./WTpet2.img ./WTpet2_Wp1.img ./WTpet2_Wp2.img ./WTpet2_Wp3.img ./WTpet3.img ./WTpet3_Wp1.img ./WTpet3_Wp2.img ./WTpet3_Wp3.img ./WTpet4.img ./WTpet4_Wp1.img ./WTpet4_Wp2.img ./WTpet4_Wp3.img ./WTpet5.img ./WTpet5_Wp1.img ./WTpet5_Wp2.img ./WTpet5_Wp3.img ./resultsPET_Tri.text

• This command will quantify, using the "triangle" wavelet-space approach, the performance of 3 warps (Wp1, Wp2, Wp3) applied to a group of 5 4D images of size 128*128*256*512 (pet1, ..., pet5). The warp rankings and results of this analysis will be saved in the output file "resultsPET_Tri.text", in the current directory. Also look at the batch file "batch_triangle". Note that the above example represents a single command-line.
