Hello Jim, I made some changes to the code essentially I substitute each 4 lines DS1-4 with one. I estimate VC which in an ideal world should be a matrix with 4 columns one for every exceedance_probability_1-4 and 2 rowsfor each unique combination of taxonomy and IM.Type. Coukd you please check the code I sent last and based on that give your solution?
Many thanks.

Just extract the columns you want from D and assign that to E.
