Selecting highest values from 2 channels to create a new channel

[siddharth_sancheti]

Hello

I am analysing two data channels with time as the x axis and a kind of random y values (both positive and negative values). I want to create a new channel which selects the highest value from the above two channels at each point on the x-axis. So, a new channel which will have the bigger value from the two channels is to be created.  I would like to create a VB script for this process of creating a new channel which will select the higher y value from the two channels (in the negative direction, it should have the minimum value). It would be of great help if someone could guide me.

PS: The red and the green channels in the image are the input channels from which the new channel is to be created. The mask channel in the image is a later step which is not of importance at this point of time.

Hello,

can you please calrify how the algorithm is supossed to work:

"Green"   "Red"    "Result"

  10             12        12

   5               6          6

   0               0          0

  -1             -2          -2

 2               -2          ???

Can you please confirm that the rows 1-4 show the right logic? and can you please add what should happen if one signal is positive and the other is negative ?
