Structure Field/Value mismatch when importing in R

[Nodragem]

Hello,
I have this code in MATLAB:

for row = 1:size(sim_values, 1) % we run only 1 simulation of 100 iterations/trials here
    disp('Current Simulation:  '); disp(sim_values{row, :});
    tic
    % run the simulation 100 times:
    [targ_RTs, dist_RTs, rall, uall]= runDinasaur2(sim_values(row,:));
    disp('time of simulation')
    toc

    tic
    results(row).keys = sim_keys;
    results(row).values = sim_values(row,:);
    results(row).target_RTs = targ_RTs;
    results(row).distractor_RTs = dist_RTs;
    results(row).firing_rate = rall;
    results(row).membrane_potential = uall;
    save('./results/distances/results_distance.mat', 'results')
    disp('time saving data')
    toc

end

That generates this:

However, when I am in R and run this code:

setwd("/home/c1248317/Bitbucket/Dinasaur/results")
library(R.matlab)
r <- readMat("distances/results_distance.mat")
r$results

I obtain:

So it seems that the last array (that should be [49,]) is not loaded.
Then the data are not attributed to the good fields.

Any idea of what is happening?
