The way I was doing this previously really sucked. But today I
completely rewrote the code for loading in multiple files and it is
now very nice. Basically, you just do the same thing you would do if
you were loading in a single file, but now you have the ability to
select several files at the same time. When you push the load button
with several files selected, all of them will be loaded separately and
then the intensity of each of images will be added together. The text
input where the one file's name is displayed will instead be a comma
separated list of all the file names. Since the input is kind of
small, it is hard to read exactly what the different files are when
you have loaded several. So if you go into the File menu bar up top,
there is a option "Opened Fille(s)". When you mouse over it, it will
present a nice list of all the files that the program has currently
loaded in. This will provide a nice sanity check if you are not sure
what files are supposed to be inside of the program.
With multiple files loaded, you can do the rest of the analysis just
like normal. When you save caked data or intensity integration data to
a file, the program will put into the comment string all of the file
names. The only think that the program can not currently do is load in
multiple files at once from inside of a macro. I am still trying to
figure out exactly how that should work.
