Here's an interesting thing...

I am doing QC on some fits that I have created - I'm staying "in touch" with my data. I load several sessions at once using:

afni -R *5.fid &

Then I set up an image window with my fit bucket overlayed to look at the stat map. And a plot window to look at the fits. I load the first session and use Opt->Tran 1D to select and overlay the fit data set - and I leave the Dataset#N plugin window open. Then I switch sessions and change the overlay Dataset#N and Set+Keep... etc.

This works for a while, then at some point, I'm not sure when, I start to get the following: The fit overlay does not display correctly. The figures I attached show the fit as a overlay on the data (fitover) and the data as an overlay on the fit (fitunder). As you can see, the fit is[/is] correct, but doesn't display correctly in the fitover.

Any advice? TIA.
