Dear Vistrails users,

We are currently working on setting up a relatively complex system based on 
Vistrails.
This requires many different VT’s to be called from the command line, each with 
several different input parameters.
The processes themselves are relatively short (a few seconds), but starting 
Vistrails takes substantially longer (approximately 30 seconds)

At the moment I can successfully do this in sequence; however, that does give a 
lot of overhead because the startup process is repeated for every batch call.
Is it possible to first give one command to start Vistrails and have subsequent 
batch commands make use of the previously started instance of Vistrails?

As a second question, is it possible to trace, for example in the Provenance, 
the values of the input parameters that Vistrails was called with?

Thanks in advance.

Best regards,

Pieter Boelen
