Write a MongoDB query (to extract a portion of data) that will be passed through MATLAB.

Job ID: 32643598

Budget: $30 – $250 USD

I have a very huge JSON file data (specifically an ECG recordings for a very long hours) that was imported into MongoDB in chunks (due to been large size).

The main task is to write a MongoDB query that will be passed from MATLAB to extract a portion of the data (for example I want to extract a 60 secs recordings of the ECG from the long hours of data recorded).

A sample of the data is attached, please note, there are over 2 million documents in the database collection.
