Hello @faizal , welcome to the forums!

It appears that the quoting has gotten very messed up in your CSV formatting. All of your criteria table rows are quoted like this:

"recruitment rate,2,2,2,2,2,2,3,2,2,C,""<enter (3) every 2+ yrs,  (2) every 1-2 yrs, (1) every <1 yrs, or (0) no score>"""

You can see that there are an increasing number of quotes every time one appears (not sure how that happened). Your best bet here will be to open up Notepad or your text editor of choice and properly quote all of the text fields so that each field is individually quoted:

"recruitment rate",2,2,2,2,2,2,3,2,2,"C","<enter (3) every 2+ yrs,  (2) every 1-2 yrs, (1) every <1 yrs, or (0) no score>"

And you’ll need to do this for the entire file. Once you have finished this, please try re-running the model with the new table.

Let us know if you have any questions,
James

Hi @jdouglass thank you for your prompt response. I just find the problem, there is a different format of csv in my office, and now the problem was solved.

I have another problem, since I ran the HRA model, the result of total_risk_ecosystem looks only half of the area of interest, here I attached the pic.

Well, the fact that there are some areas present and not others make this look like a data issue. I can’t identify just from this image which layer might be at fault, but could you make sure that your AOI covers the whole area you expect, and also that each of the aligned_* rasters in your intermediate folder look as you would expect?

If that doesn’t get you to the specific layer that’s missing data, please share your complete set of inputs so I can take a closer look. The easiest way to do this is by sharing a data archive from the InVEST workbench.

Thanks,
James
