Consistency issue:

     DSI Studio has a very high turning rate, and it is possible that the computation outcome may differ slightly between versions. Therefore, I would recommend users keep a local copy of DSI Studio for each research project and only update DSI Studio if a new project is initiated.

Hardware recommendation:

     DSI Studio uses a lot of multi-thread processing. Although it can be used on most laptop or desktop, the best performance will need a computer with multi-cores that have of many processors (e.g. A minimum memory of 2GB is needed, but if a large number of tracks or image volumes are expected, DSI Studio may need 32GB of memory or more. GPU computation is not yet supported in DSI Studio.
