Collecting multiple .json objects in one .json file?

Hello everyone, I'm developing a deep learning Mask R-CNN training.

I have labeled images through imageLabeler and I got the annotations as gTruth file. Then I have converted these files in .json objects using the following code :

annotationsFileName='gTruth_coco.json';

exportGroundTruthToJSON(gTruth,annotationsFileName,'COCO',true)

Now, the problem is I have to collect these .json files in one .json file.

How can I do that?

Many thanks for your attention and your kind help.

You can open the json files and append them one after another. Following is how you can achieve it.

st1 = fileread('data/label_data_1.json');
st2 = fileread('data/label_data_2.json');
[fid,msg] = fopen('combined.json','wt');
fprintf(fid,'%s\n%s',st1,st2);
fclose(fid);

Here 'combined.json' will be your desired json file.

To perform the above operation on Linux system without MATLAB, you may run the following commands in terminal

touch combined.json
cat data/label_data_1.json >> combined.json 
cat data/label_data_2.json >> combined.json
