After estimating the cointegration, I am interested to estimate the vecm model

. So i want to know the following parameter on error correction term on each equation for the spot and futures price respectively. I want to know how to get the parameter after estimating in CATS.

While you can get that out of CATS, you're better off with a system like that to let CATS help you figure out the rank and do various diagnostics, but then have RATS actually estimate the VECM once you've settled on the specification. Use @JOHMLE to estimate the cointegration vector (it will give identical results for an identical model) and SYSTEM with an ECT instruction to set up the VECM. See Section 7.8 and Example 7.7 in the v8 User's Guide.
