Dear listers;

I want V4 users to answer the following questions:

*       Rain 0.0 appears in Overview.out file. Why?
*       We have calculated the harvest index with the formula below:
Harvest index= (grain weight/spiky grain weight)*100
            Can you tell me which harvest index I calculated HIAD or
HIAM or Product harvest index(ratio)?
            HIAD: harvest index (grain/top) (unit) in T File
            HIAM:harvest index at maturity in A File
            Product harvest index (ratio) in Overview.out File
*       HWAT.....Harvest product wt (kg/ha) Does this include
spike+leaf+spikelet+grain ?
*       Is tops weight (kg/ha) the quantity of dry material?
*       What do you suggest that I calculate my two different wheat
genotype coefficients ?
V3 doesn't operate and I can't see Gencalc on V4.
*         What is Random number seed in simulation options?
