Unable to find response variable in the workspace

My dataset has two columns, time and strain.I am trying to load my data that is in .txt format in the Classification Learner App, but it says the following-" Unable to find response variable in the dataset ".

What does that mean and what should I do to fix this?

Hi Krati,

As per my understanding, you are facing an error message “Unable to find response variable in the dataset” when trying to load data to Classification Learner app.

Please note that response variables can be numeric, categorical, string, or logical vectors, cell arrays of character vectors, or character arrays and that the response variable cannot contain more than 500 unique class labels. Please check if your input data matches the above mentioned categories. To know more about selecting data for Classification Learner app, refer to the following documentation https://www.mathworks.com/help/stats/select-data-and-validation-for-classification-problem.html.
