Of course, you can specify which tracts you want to reconstruct in the configuration file. Both the sample configuration file in $FREESURFER_HOME/dmrirc.example and the tracula tutorial have the info on how to do this. On Thu, 5 Dec 2013, David Soto wrote: Hi, just a though, would it be

2013-12-05 Thread Douglas N Greve
you cannot do this in QDEC. In fact, it is a tricky analysis to do properly. For each group you will need an offset regressor and an age regressor, but only the patient group will have a burden regressor. This cannot be done with an FSGD file either. You will have to create your own design
