Thank you Dan, I appreciate your help! ATOM has allowed me to see the text code unadulterated and helped me troubleshoot; I've managed to achieve what I wanted to: I am adding stage coordinates to an existing *.spd file already containing a sample reference position. I'm calculating the new positions, relative to the reference position, in Excel after spd import; then saving to tab delimited text file; then opening in Notepad to remove extra space added by Excel between all text via Find/Copy/Replace; then re-saving the file to remove the *.txt at the end of the filename; then opening in ATOM to check that there is one extra line at the end of the code (and modifying if I need to); and then re-importing into PC-SEM. Best, Deon. **** JEOL Probe Users Listserver Moderator: Anette von der Handt, [log in to unmask], Electron Microprobe Lab, University of Minnesota Post a message: send your message to [log in to unmask] Unsubscribe: send "SIGNOFF PROBEUSERS" to [log in to unmask] On-line help and FAQ: http://probelab.geo.umn.edu/jeoluserlist.html *
