I love that it is easy for me as a user to create new analysis types by simply adding parameters or creating entirely new equations from scratch without having to go through lengthy certification procedures. It would be nice if there were more options under 'advanced' features since they do sometimes disappear when you close out a tab after using them. If you are looking for something simple but robust then give this software a try. We have been able to use our own custom analysis instead of waiting for approval from other groups who might not understand what we need.
