Just a small clarification of the previously posed question. The data structure of the file is ordered the following way:
First 6 images belong to slice 1 with 6 increments of TE (20, 40, 60, ..., 120 ms). Next 6 images belong to slice 2 with 6 increments of TE, etc. In other words:
Image Slice TE(ms)
1 1 20
2 1 40
3 1 60
4 1 80
5 1 100
6 1 120
7 2 20
8 2 40
etc...
I hope that helps.
