Hello again!
I saw that some other people had similar issues, but it looks like the assumption is that this
means nothing (can ignore it), but because I am sort of learning as I go, I would like to tell you
what I did and see if maybe the warning is because I didn't handle the data correctly (which I
suspect).
I used MRIConvert to get all the files converted to 3D format.
In each run, there are 290 image files that I had to fix because the sagittals were all upside down.
No sweat there.
I went to FEAT, mostly because I wanted to do motion correction (can't figure out how to separate
this from FEAT, as I am a UNIX idiot), and when I realized I needed 4 D, I went back and
reconverted the files to 4D in MRIConvert. Since I knew the sagittals would be flipped, I did a
fslswapdim on the 4D file (seems to have worked).
I used that swapped file in the FEAT Data where it says 'Select 4D data' (seemed a no brainer that
that was the file they wanted). Because there are 290 images taken in the run, I put 290 in total
volumes (first question- is that incorrect?).
FEAT is Running, but it is giving me rows and rows of this warning:
Prestats
Total original volumes = 290
Deleting 3 volume(s) - BE WARNED for future analysis!

Is there something in this warning that will tell me what I need to correct to get it right?
Let me know if you want the full details of what I actually entered into FEAT to make it work.
