Fslvbm in nipype

Hello ppl,
I am trying to implement some VBM analysis using python and compare it to CAT. Therefore I would like to use the FslVBM but i cannot find it in nipype. Is it under some different name or it does not exist? If it does not exist, is there any specific reason for that (such as technical issues) or it is just not there yet due to lack of time etc?
So far I only found Fluid_NiPype. Does anyone know another python tool for VBM?
