I think I wasn't clear... I was making a user interface point, that in order to request simultaneous sampling in two directions, according to the documentation you have to add the line "alchDoubleWideSampling on" in your configuration. I thought it would be intuitive to skip this and activate TI if only "alchLambda" is specified; use straight FEP if both alchLambda and alchLambdaPlusDelta are specified; and run double-wide sampling if alchLambdaMinusDelta is additionally specified.
