Hi, even if I can imagine such change in principle, I feel that more appropiate solution could be: - if this operation is performed systematically (and I think that for forward and backwards scans this would be practical in many cases, not only for dIdV maps) and a reasonable functionality is discussed (what could be options, what kinds of results can be determined), a module could be created for forward/backward scans handling, - if you use Python scripting interface in Gwyddion you can do much more than only combine channels with offset. And it can be really fast. Best regards, Petr ------------------------------------------------------------------------------ What Every C/C++ and Fortran developer Should Know!
