Hi. I have a table with three columns potential, intensity and time from experimental data. The main column is the potential. It increases from 0 to a maximum value and then it returns to cero. If I represent E vs t, its like /\ (increases and decreases). But I repeat it /\/\/\ in different cycles so, in the same table I have different cycles and it increases and decreases few times.
In this way, I have only one table with three columns of all the cycles. I need to separate cycles. Is it possible to indicate in a program that it separate the data in the different cycles from the main table: from 0 to the maximum value (/) and from the maximum to cero (\) (for potential, intensity and time)?.
I have a program but it separates by time and not by potential. The problem is that if I change the potential, the cycle its longer and the time changes too. But here I indicate a constant value of time so it divides it before the E maximum value appears.
wxt test:="col(A)[i]>=0 AND col(A)[i]<=24,75" iw:= [Book1]Sheet1 ow:=[C01]Sheet1;
The E max changes so, I need to indicate that it must separate the data when it arrives to a maximum value of E (whatever it is) and not in a constant time.
I know its complicated and Im a begginer. Thanks!!!

Hi, Fulerena
I'm thinking running a peak finding to locate all peaks, both positive and negative. And then using these peak centers to separate the wks.

Separate data of a table
