It is the very procedure I am now seeking. My matrix files (.spe) are generated by Princeton Instruments Camera.
I understand that I have to load .spe files instead of .dat by using this useful procedure "Load All .dat Matrix Files From Folder", and I also noticed that there was a procedure "Winspec.ipf" or "SpeLoader.ipf" available.It can help load .spe files. http://www.igorexchange.com/node/2756
My question here is how to combine these two together to get a new procedure to directly load .spe files. Many thanks.


Make some changes before you have to.
