Matthew

Hello,
thanks a lot for your help,

it is more clear, now.
In my special case, I have 1mm voxel size, but how could define what are my voxels dimensions? I use MNI 152 coordinate space.

Hi AV,

The TR is generally only relevant if you are dealing with fMRI time series - for other types of 4D data, you can just set it to 1.

Cheers,

Paul

OK for the tsize,
but in the case of the TR is not clear: I am using a txt file that is the join
of different txt files that were generated from FSL atlases. How can I cope
with the TR in this case?

Thanks
AV
