ERROR: Incorrect input current [A]. For constant current, type a single value (for example, -0.015). Positive values correspond to cell charging where the anode is lithiating and the cathode is delithiating. Negative values correspond to discharge. For time-varying currents, provide a two-column table (the first column is the time in seconds, the second column is the current in Amperes). The table can be copied and pasted into the field directly from a spreadsheet (e.g. MS Excel). The values between the points will be linearly interpolated.
