Cannot load './results/options.mat' while running flandmark_learn.m file

[khalidiitdu]

I am trying to run 'flandmark_learn.m' file, but it's getting following error:

Error using load
Unable to read file ./results/options.mat: No such file or directory.

Error in prepDataForLBP (line 27)
load('./results/options.mat');

I noticed that 'options.mat' is saved into './code/MAT/' directory (save('./code/MAT/options.mat', 'options');--->flandmark_learn.m, line no: 83 )

If I make changes in 'prepDataForLBP.m' file from "load('./results/options.mat');" to "load('./MAT/options.mat');", In that case it shows following error message:

Reference to non-existent field 'S'.

Error in prepDataForLBP (line 30)
S = options.S;

Error in run (line 57)
evalin('caller', [s ';']);

Error in flandmark_learn (line 160)
run './code/prepDataForLBP.m';

run
Error using run (line 23)
Not enough input arguments.

What should I do???
