Michael;
1) Are you using measured weather data? If so, the weather methods code in simulation controls should be "M" for measured, not "W" for generated with WGEN method.
2) Use the day of year format for your fertilizer dates. Negative days after planting are not supported by the model.
3) Each planting date should be in a different planting level, unlike fertilizers which can have more than one application per level.

Subject: Questions for tomato experiments
Dear all,
I am programming a tomato experiment and i have the following questions
1) I have generated my weather file using Weatherman, when i try to run the experiment i am receiving the following error message:
Missing WGEN data in climate file
Line 27 Error key: WGEIN
Does this mean that the weather file has not been imported properly or that the data are corrupted? In the weatherman the file seems perfectly fine
2) I want to incorporate in the model pre-plant fertilizing. On the management days for fertilized can i chose the days after planting and include a negative number (i.e. -7 indicating a week before planting) or i can only put reported dates for pre-plant?
3) On the planting dates, when i add different plant dates, after i do save, when i restart the program, on the level 1 section it keeps appears the same, while in every other section i.e. fertilizer, irrigation etc. when i add days then they appear differently on the section below
Thank you very much for your help!
