Select rows by minimum values of a column considering unique values of another column

I want to select only the rows for each unique name of a column (first column) that have a minimum value in another column (sixth column). This is my data in matlab.

I want to select a row for each unique name_file that has its minimum value in Z_value_Secondcriterion.

Any idea about how to do it Matlab?

A=Results{:,1};
B=str2double(Results{:,6});
C=(1:numel(B)).';

G=findgroups(A);

sel=splitapply(@(b,c) c(find(b==min(b),1)), B,C, G);

Selection=Results(sel,:)
