    extracting threhold values from a data set

    Dear all,

    I have a data set containing multiple verticle ground reaction force curves recorded from a running session on a treadmill which has strain guages that measure the vGRF for each step.

    I will then be dividing the vGRF data by body weight to get the acceleration of the curve

    from that I will then be looking at the impulse etc.

    what I would like to do is develop a code/script or formula that will pick out data points that are above a certain threshold (~3m/s/s) in the acceleration curve data and then put that data into a seperate column. I am a complete beginner with VBA and my excel skills are very basic so any help and advice on where to start with this would be much appreciated.

    I have attached some sample data to this post to help with the explanation of what I am trying to achieve.

    kind regards

    Hi,

    thank you for the reply. I have attached the example data again. In the acceleration column (column C) i have highlighted all the cells green that have a value less than 3m/s/s which is my threshold cut off. I have then shown a scatter plot of the data that I would like to be left with in column D. I hope this is clearer

    best wishes

    will

    Drag Down (this is a helper column for results in column E,can be hidden if you like)

    In E2:

    Format as number with 2 decimal places (so it matches column C display), Drag down
    See Attached

    Hope this helps
