Hi,
I need an exponential equation with two time constants to fit a sodium current tracing. You can find two attached images: the equation I need is Two exponentials and the red tracing which is the one I need to fit (the range is between lines 1 and 2).
The clampfit provides custom function, which is good. But I don't understand how to set seed values and I don't even know what seed values mean, and how to determine the seed values? Anyone can help this? Thank you so much
