Sergi, Your VTI file extents should only describe the region of the whole image they occupy, so you are on the right track. In situations like these where it isn't obvious what is wrong, I tend to start from the beginning with a very small example and build up from there. For example, you could start with a small image - say 2 x 4 pixels (2D) split into two pieces. Start with one data array for this example and make sure it works - use ASCII encoding so that you know for sure what is in the XML file and then switch to raw binary, then zipped binary. Then add a second data array. When you are confident that works, change the example to four pieces, then make the image 3D and so on.
It can take a while to do this, but you'll come out really understanding the file format and will probably figure out what you had wrong in the first place.
