[Insight-users] Error on running Diffeomorphic Demons method

[Ganesh Narayanasamy]

http://www.insight-journal.org/browse/publication/154
While registering a pair of 3D-CTs using Diffeomorphic Demons method and most of the default parameters, I noticed an error that cropped up about 2/3rd the way through. This is a 3 level resolution registration process and the error cropped up after the 2nd level saying "Failed to allocate memory for image.". Can you guide me to complete the entire registration using this method. The error message displayed on the screen is shown below (briefly).

Can someone also educate me what is meant here by MSE (mean square error?) and also the "harmo".


Thanks,
Ganesh
