Hi Leon,

SCIRun isn't currently setup to be run / controlled by external applications. This is something that we are working on, but at the moment, it's far more efficient if SCIRun can act as the "driver". There are several examples of SCIRun driving an optimization loop that we release with the SCIRun distribution -- for example the SCIRun/src/Packages/BioPSE/nets/conductivity-search.net network.

Cheers,
Dave

G'day,

I am using a program that can estimate the parameters values in a model.
It does this by running the model, and then compares the experimental
measured data with the model output data. It then adjusts the model
parameters values to minimise the difference between the two sets of
data. It repeats this process over and over until there is little
difference between the measured data and the simulated data.

I have created a network in SCIRun to setup a mesh, assign parameters,
setup a finite element matrix, and then solve it.
I was thinking of running the parameter estimation program within SCIRun
by created a module that runs it, e.g. system(“/home/lgraham/paramest/”).
When preparing the parameter estimation program, it requires the
executable file name (or command line) of the model to run it, which is
defined in its setup file.
I was thinking of some how executing the network by a command line, so
that the parameter estimation program can run it.

Does anyone know how to do this? Or know of a more better way?



Leon
