Hello all, We are using DARTEL for VBM. In the past, we have analyzed a big group (N=98) with DARTEL already and have gotten some decent results. However, now when we are looking at a subset of our previous dataset (N=27) and running DARTEL using the 'existing Template' option, we get the following error. Running "Run DARTEL (existing Templates)" *** rc1V00763 *** Error running job: Error using ==> spm_dartel_warp Incompatible dimensions between images and template Any suggestion and/or help will be much appreciated. Thanks -Muhammad
