MCCL troubleshooting on Mac for Jun 22 Version Release

[Samantha Zerafa]

Hello,

I have been trying to utilize the MCCL application on my MacBook and perform the subsequent visualization in MATLAB and seem to be running into some issues. I have been following the tutorial here and the command line portion runs well, however when I try to visualize in MATLAB like the example given, I run into some errors. I have my load_results_script.m in the same working directory as the JSON files, however I get an error on line 1498 of the loadMCResults.m file that there is an unrecognized file "loadjson". I am happy to elaborate/attach photos of the error.

Sorry if this is a user error or very simple question, I was just wondering if this is a known bug or if I somehow am following the example incorrectly. I am using MATLAB version 2020a. 

Thanks!

Hi Samantha,

Thanks for your interest in our software!  I *think* the problem is that it can't either find the folder "jsonlab" or that the filename and/or location where the results reside is incorrect.  To solve the first, on the left hand panel "Current Folder", right click the folder "jsonlab" and select "Add to Path -> Selected Folders and Subfolders".   To debug the second, let me know what you've specified for "datanames" and "outdir" in load_results_script.m.  A photo of the error would definitely help debug this one.

Thanks!

Hi Carole,

Thanks for your quick response! On the first point, there actually is no "jsonlab" folder within the zip file I downloaded "MC_v6.0.0_Mac_x64" rather, a ton of individual icons labled "jasonlab\jsave.m" etc.  Should all these files just be within the folder jsonlab rather than in the main folder with "jasonlab\" in their title? I made sure to add that whole MC_v6.0.0 folder to my pathway like you described and I still get the error.

On the second point, the datanames and outdir lines are as follows:

datanames = { 'one_layer_all_detectors' };

outdir = '.';

So it is possible I am defining. one of these wrong since I left them as is for the first example. For reference the file I ran in line is this:

"./mc infile=infile_one_layer_all_detectors.txt"

Here is a picture of some of the errors I have been getting:

Thanks!

Hi Samantha,

Yes, all of the files that start with "jsonlab/" should be in a subfolder named "jsonlab" (no "a" after "j").  When you extracted the zip, what did you use?  Unfortunately I don't have access to a Mac, however on Linux I use "unzip".  I see that you're trying to plot the results from the example infile.  Great!  Since your "outdir" is set to ".", just make sure that the results folder "one_layer_all_detectors" is sitting in the directory you are running MATLAB (the MATLAB command "pwd" verifies what the current working directory is).  I think once you have the jsonlab files in the correct folder, all should run.

Keep me posted.

Thanks,

Carole

Hi Carole,

Thanks for your help! I think my zip file originally had some sort of error, once I tried it again with the terminal command unzip I was able to get the proper folders and the MATLAb is now running without error. Once I dive into this a bit more I may have follow up questions on the time domain functionality of VTS, but I will create a separate chain for that since it is a different topic.

Thanks!
