Zati,
I don't have Origin 6 installed but you can try this.
Once you have your data in column 2, open the Script Window. Add the following script, select it all, and press the Enter key to run it.
The first three variables are the values based on the image in your initial post.
It should populate column 1 with data starting with the "LEFT" value to the "RIGHT" value with the number of rows being the same as the "SIZE" value.
double dX1 = 220.01409912109375;
double dX2 = -18.90661953002647;
double dNumPts = 32768;
double dInt = (dX2 - dX1)/(dNumPts - 1);
col(1) = data(dX1, dX2, dInt);
I would suggest that, since you are very new to Origin, you considering trying the latest version (Origin 2015). Considering that there is much to be learned, you might as well learn by using the most recent version rather than investing time learning in a considerably older, more limited, version.
