Matlab Production Server Error Using Load Command

Hello,

When using the load command in a script compiled to a CTF file running on Matlab Production Server, for example:

dataset_load = load('results/dataset_scaled_fixedBins.mat');

I get the following error:

Error: Unable to read file 'results/dataset_scaled_fixedBins.mat'. No such file or directory.

I put the .mat file in the auto_deploy folder, but it is not found. I then put the script in the script's .m file path

C:\\Program Files\\MATLAB\\MATLAB Production Server\\R2019b\\script\\mps1\\.mps_deployed\\phase22_generate_histogram2_27\\phase22_gene\\phase22_generate_histogram2.m

but that does not work either.

Where does a script look when using the load command from a CFT file?

I ran into the same issue while trying to load a file in a deployed application. Because you know the structure of the folders you deploy, you can make use of Matlab's mfilename function. The following worked for me:

path = mfilename('fullpath');                                   % retrieve full path of current script
path = strrep(path,'\[folder]\[current_function]','');          % remove part of the path
path = fullfile(path, 'results\dataset_scaled_fixedBins.mat');  % add new end to the path
load(path);

Where [folder]\[current_function] represent the folder structure of where this code resides, while 'results\dataset_scaled_fixedBins.mat' is the structure that is added to complete the path.

I hope this helps!

You can check by the work folder of the CTF file by using pwd in MATLAB Production Server. I suppose now the work folder is C:\Program Files\MATLAB\MATLAB Production Server\R2019b\script\mps1.

So, if you put dataset_scaled_fixedBins.mat file in C:\Program Files\MATLAB\MATLAB Production Server\R2019b\script\mps1\results, it would work.

But C:\Program Files\MATLAB\MATLAB Production Server\R2019b is installation folder and it's not a good way to put input data or CTF files in this folder.

I recommend to set up an instance in other folders than C:\Progam Files.

For example,

mps-new C:\Work\mps1
