Can I vary the NOISE SEED in the .vsc text instead of the checkbox?

Post by aliakhavan89 »

Is it possible to manually add this option in the .vsc file as a text? (to avoid the hassle when using cmd/dll)

Not if you're using the File method. But every time you run an mcmc, it now generates a vsc that runs the sample with that box checked.

For other methods (multivariate, latin hypercube) you can add NOISE SEED=VECTOR(...) to the list as an alternative.

Thanks a lot, Tom. Yes, I'm doing sensitivity after MCMC, and all I had to do was to include NOISE SEED as a variable in the model and set MY_SEED = 0, which goes into the Random functions. Such a nice feature! Thanks a lot!
