Hi,
Has anyone ever tried to run the Texas-2000 bus test system in MATPOWER to
find its power flow and optimal power flow solution. I am getting the
message like the following while trying to run it,

For Power-flow:

Struct contents reference from a non-struct array object.

Error in newtonpf (line 34)
tol     = mpopt.pf.tol;

Error in runpf (line 220)
            [V, success, iterations] = newtonpf(Ybus, Sbus, V0, ref, pv,
pq, mpopt);

And for optimal power flow:
Struct contents reference from a non-struct array object.

Error in opf_setup (line 20)
dc  = strcmp(upper(mpopt.model), 'DC');

Error in opf (line 198)
om = opf_setup(mpc, mpopt);

Error in runopf (line 75)
[r, success] = opf(casedata, mpopt);

Though to me it looks like the MPC like other cases. I have loaded the case
file : case_ACTIVSg2000.m

from Texas A&M university's repository.

Regards,
Jubeyer
