Matrixtable instance has no field - Error message

Hello Everyone,

I was following the tutorial for workshop resources where I was able to see the below two commands

mt.DP.summarize()
mt.AD.summarize()

But when I execute them, I get the below error

AttributeError: MatrixTable instance has no field, method, or property 'DP'
    Did you mean:
        MatrixTable method: 'drop'

AttributeError: MatrixTable instance has no field, method, or property 'AD'
    Did you mean:
        MatrixTable method: 'head'

But in the YouTube tutorial I see the same code working. May I know whats the issue here?

Is it due to VCF files?

yeah, I’m guessing your VCF doesn’t have these fields. You can look at the schema with mt.describe().
