In Rietveld refinement, I'm using a "Linear Interpolation" for the background (BG) data. I used the WinPlotr to manually select the BG points (file containing 133 points).
In the attachement, you will notice that when the BG file in imported to the pcr Editor, only 100 points are imported (missing the rest of the file).
I got a message saying "some fields are undefined". Does this mean that the number of points in file is limited and should not surpass a 100?
