Experience with Matlab's TMG

I have been playing with Matlab's TMG and here are my 2 cents from experience with the software

Pros: Easy to install, Easy to index a corpus and queries.
Cons: Proprietary code. Impossible to contribute modify or fix bugs in the code. Is not maintained well. Does not have any discussion forum where users and developers can communicate. Last citation was 2009

I was unable to even run some basic retrieval tasks due to bug in the code. norm2 does not work for sparse arrays and one needs to replace norm2 with normset, and I was unable to make the change because the code is protected and proprietary.
