Hi Theo, 

- not sure what test you mean. Have a second person correct the data and 
compare ?

- you can run 1.5. and 3 T data in the longitudinal pipeline, however (similar 
to cross sectional processing) you will not know if the differences of the 
results are due to anatomical changes or due to scanner differences. 

Best, Martin
