Finding maximum point for each echo

Hello everyone,

I am measure 1H T2 times of a basic polymer by solid state, and the data I acquire is given in 50 echoes of about the same size. I tried to create a pulse sequence to acquire only the echo maxima for each point, however this effort was futile and never seemed to work.

I have attached a copy of my data, and what I was wondering was if there was any way to write a formula that could pick out the maximum points for each echo. I can do this by hand, but later when I have large number of data sets of various sizes, a formula would definitely help. In the end, I need 50 points for each data set, not the ~7000.

Thank you very much!

Thank you very much! That seemed to work well with a little modification (see attached). Now my only question is how do I find the x-point that matches with the value for the echo maxima (in column D)?

Thanks!

This should have it for you. I used the offset function with the Match Function to get the proper row offset.
