I am somewhat surprised that the estimation takes so long. On a similar computer system it should take about 15-30 minutes. Do you have images with spatial resolution of 0.5mm or smaller? However, even for images with 0.5mm isotropic resolution the execution time is too long. There is a debug option in VBM8 that prints out your configuration. This might help to find the bottleneck.

The estimation is independent from the previous subjects, thus you can restart with subject #44.

In VBM8 no custom template is created anymore.
