Dear AFNI Gods,

Having looked at my data as a multitude of different alternative datasets-- with different permutations in their creation such as:

Different smoothing kernels,
Different bandpass-filter application,
Different compositions of indivudual subjects in group merge maps, etc.

it is sometimes a challenge to keep them all straight without having obnoxiously long filenames or a post-it note on your monitor.

While this kind of info on all the preprocessing etc. is all chronicled in '3dinfo', I was wondering if a future AFNI release could incorporate into dataset (headers) a subset of free-entered string text that could be accessed while looking at data with the GUI.

e.g. toggle buttons for "Underlay Notes" and "Overlay Notes" that would access the string of text linked to the header of the two datasets being viewed.

Maybe allow for a command line (or in a script)

-text_note dataset+orig 'This is a merge map of AFNI addicts with outlier patient jb exlcuded'

that would specify what would appear in the pop-up menu in the GUI-- even with tlrc-warped variants.

Also keen would be an feature in the GUI itself to add to the .HEAD file text string easily, such as simply providing a button to allow editing on the fly when notes are opened and viewed!

Part of why this is salient is that my Section Chief (and boss) on occasion needs to look at my data in our image database and it would be helpful for him to be able to click on a button to quickly see exactly what each dataset means.

Perhaps AFNI already does this, and if so, I would appreciate knowing how to activate such an annotation feature.
