From the contents in your
MNI_ICBM_2009b_NLIN_ASYM/dartel folder as you showed, it seems the function
ea_create_tpm_darteltemplate (which will generate all the dartel and shoot files) didn’t run through. Maybe you can delete the folder
MNI_ICBM_2009b_NLIN_ASYM/dartel and the file
MNI_ICBM_2009b_NLIN_ASYM/TPM.nii, and run
ea_create_tpm_darteltemplate again from MATLAB command window. You can then send me the full log. I will check out what’s happening during the template generation.
