The projections can be run directly from a Hist object using the Project function:

myMSE <- Project(myHist, MPs=c("AvC", "FMSYref", "Itarget1"))

## Checking MPs

## 1 / 3 Running MSE for AvC

## ..................................................

## 2 / 3 Running MSE for FMSYref

## ..................................................

## 3 / 3 Running MSE for Itarget1

## ..................................................

Note that the runMSE function is a wrapper for Simulate and Projects, and:

myMSE <- runMSE(OM, MPs=c("AvC", "FMSYref", "Itarget1"))

would result in an identical MSE object.
