File Upload

Uploading data

1. To upload, add a new device, select Upload a file and a new popup will appear

2. Here, you must upload the original zip file used for the recording. You may also make small changes and compress the files into a new zip, but the web app may fail to reproduce those files.

The object that is being played back should behave similarly to a connected device. You need to click on the play button to start streaming the data. Once the file ends, playback will stop, but you have the option to start again, rewind, or loop.

Recording data

1. To record a file, simply start streaming using your device and press the record button, accessible at any time from the "devices" window.

2. It will save the streamed data to your computer as a .zip with multiple .csv files that contain data points, timestamps, and some metadata.

Avoid deletion of the .zip file if you ever want to play back the pre-recorded data.

Information about pre-recorded data

The files recorded for this application will typically follow the convention deviceName_datetime. They will be downloaded as a zip file with the following minimum contents:

• README.txt with basic information about the folder and its contents.

• metadata.csv where the devices and files are described and correlated

The other files will be .csv recordings of the datastreams. If you ever want to unzip a folder, modify a file, compress it, and re-upload it, it is important to avoid modifying the files above, otherwise it might not work.
