Find index of specific rows of a table with value greater than a threshold

Hey, I have a data table (143 x 8). From this table, for column 8, I want to search row numbers 72 to 112, for values greater than 0.54. I want to then use these indices to give these points a different color in my scatter plot. I am currently using find:

ind2 = find(T{72:112,8} > 0.5426)  %Correctly classified test points 
ind3 = find(T{113:143,8} < 0.5426)  %Correctly classified test points 
scatter(X1(ind1),Y1(ind1),'b','filled') %Cal data is blue
scatter(X1(ind2),Y1(ind2),'g','filled') %Correctly classified data is green
scatter(X1(ind3),Y1(ind3),'g','filled') %Correctly classified data is green
scatter(X1(69),Y1(69),'k','filled') 
hold off

The ind2 output is : 1 2 4 5 6 8 10 etc

i.e. it tells me that starting from the 72nd row, the 1st value meets my criteria (> 0.54), the 2nd does, the 3rd does not and so on, which I verified is correct. But I want to now the row index, in order to shade the accurate points in the plot!

The find works fine with variables, i.e. it outputs the row number. I don't know the issue with tables :(

Please help!

Try the code by adding (initial index - 1) to the find function

ind = find(T{initial_index:final_index,column_index} > threshold) + (initial_index - 1)
