    Hi David,

    My apologies for the delay in answering you! If you haven't gotten this to work yet, I recommend gridding the data using the nearest neighbor gridding method (you'll need a z column, but you can just choose your x or y column for z if you don't have data measurements). Enter the x and y min and max from your data file, and the desired spacing you were trying to collect points at, and then save the result as an x,y,z DAT file. This will result in a very similar file to what you have, but with evenly spaced x,y points. If desired, you can open this DAT file in Surfer's worksheet to delete the z column.

    Thanks!
