Dear Chao,

It is easy to use this application on the command line:

    mps_overlap --mps1 MPS1.task.out.chkp --mps2 MPS2.task.out.chkp

You can also type `mps_overlap -h` to see help text. If you want to use python, `subprocesses.call()` function from `subprocesses` module or `os.system()' from `os` module will help you.

Best,

Rongyang

Dear All

I would like to use application 'mps_overlap' to calculate the overlap of two MPS wavefunctions with the checkpoint files MPS1.task.out.chkp and MPS2.task.out.chkp. However, I do not see any tutorial or document about how to use 'mps_overlap' with python. So how can I get the overlap of these wavefunctions?

Best wishes!

Yang Chao
