We don't have a way to do a power analysis directly from QDEC. I have some matlab code that does it for univariate analysis.
In the QDEC output folder, you will see a glm folder. In that there will be folders for each contrast. In the contrast folder, you will see an F.mgh file which will be the F-values. You can convert this to a t = sign(gamma.mgh)*sqrt(F)

Hi Would you please let me know if it is possible to calculate the power for a group comparison in cortical thickness? Also, a referee is requesting F-values and T map , are they generated by q-dec? That would be great if I can get an answer in more detail since I have seen the post in FAQ, just need more information in detail regarding calculating the power ! -- Best regards, Amirhossein Manzouri
