How do I remove the drift from this signal? I want the "flat" lines in beginning and the end to be at the same level.

There seems to be an integrated square-wave pulse in the centre half of the data. What are your data and how are you acquiring and initially processing them?

Image shows what I meant with baseline. Baseline 1 and Baseline 2 are suppose to be at same level, but I had a drift in my measurement (signal = intensity). I want to remove the drift without distorting (changing) the amplitude of my bump.
What I am interested of here is the amplitude of this "bump" and the response time.
Many thanks!

Use the detrend function.
