The first thing you should be greeted by when you start a CellexalVR session is one or more blue boxes and a weird blue machine. You may need to turn your head and look around before finding them. The boxes around you each represents a folder of data that can be loaded. If you don't see any boxes you probably forgot your data and/or placed it in the wrong folder. The folder with your data should be placed inside a folder called 'Data' inside the folder where CellexalVR is installed. If you need help locating this folder, you can press escape on your keyboard to bring up the settings menu, scroll to the bottom and click the "Open data folder" button.
The names of the datasets (the names of the folders) are written on the boxes. If you have many datasets, you can use the small keyboard located to the left of the loading machine to search for a dataset.
To load a dataset, move a controller close to the box and it will open. Use the "grip buttons" on the controllers to pick up the balls inside and throw them into the funnel of the loading machine. The boxes and the loading machine should fall down and you should see your data. Just like you just picked up the balls you can now pick up and interact with the graphs. Loading Data & Using the Menu
