Dear Lukas, > ...hoops... > > I've forgotten to ask a second question: > > Is there any way to get the registration parameters into an ascii file??? Yes: Be fname.mat the filename of the mat-file with the registration parameters in it. (fname.mat is written as a result of the realignment procedure.) Then type within matlab: load fname.mat save fname.asc M -ascii where fname.asc is a filename of your choice. Best wishes, Stefan -- Stefan J.
