Elegant way to know in which iteration of for I am

At the moment I have something of the sort:
n_runs=0;
N_categories=[17, 8];
for protocol_ID=[4 1 7 6]
for t=1:nTrialsPerBlock
n_runs=n_runs+1;
if n_runs > N_categories
(--code--)
end
(---code---)
end
end
What I am looking for is a way to evaluate in which protocol the first for is (meaning if it is in 4, 1, 7 or 6) and then if it is in the first two, should be n_runs > N_categories( 1 ) and if it's the second pair N_categories( 2 ).
I am trying to code it so that it determines in which protocol I am, and according to that evaluate if the number of runs is bigger than the corresponding N_categories. Note that protocol_ID could have any of the numbers (4,1,7,6) in no particular order.
I am not seeing a better way than a bunch of switches/if's. Anyone could give a hand? :)

...Can a switch work if I do:
switch protocol_ID
case 1 || 4
case 6 || 7
Not in that exact syntax, no, but
switch protocol_ID
case {1, 4}
...
case {6, 7}
...
otherwise
...
doc switch % etc., for details...

I don't follow what the end objective is from the description, but to know which iteration numerically is being evaluated you've got the indicator variable being incremented in the wrong place--
iter=0;
N_categories=[17, 8];
for protocol_ID=[4 1 7 6]
iter=iter+1;
if round(iter/2)==1
% stuff for first two
else
% second two
end
...
