Hi, my name is David Kiamanesh and I am a second year medical student
at WashU. I am beginning to learn Caret so that I could map fMRI data
which I have collected from published papers. I have been working on
learning how to use the stereotaxix foci feature which Caret has and
it is great. I have come across a couple of things however that I was
hoping you could help me out with.
1) For some reason every once in a while, in the D/C under Foci, in
the colors tab the new foci I entered will be awkwardly placed, not
indented like the rest of the list. Any subsequent foci that I define
would then be listed directly on top of the last one, i.e. the words
will be on top of each other, therefore unreadable. I really have no
idea why it does that, I've tried saving the data file and restarting
it and it appears that the problem goes away, so I really dont know
what the deal is with it.
I have never seen this myself. Like you, I have no idea what the deal
is with it.
2) I'm unclear what the foci projections are. I saved the foci
projections and then loaded it the next time and some of the foci were
duplicated in the foci report, off by about 0.000002. I'm not sure if
I need these projections or what exactly they are.
Projecting foci allows you to to view them on a surface other than the
fiducial surface. I think of foci as free points out in space;
projecting them attaches them to the closest tile in the active
fiducial. If you load both the foci and fociproj files concurrently,
you will see duplicates. You shouldn't see dups when viewing one or the
other.
I appreciate any help that you can give me and would like to thank you
for offering such a powerful and well designed program for free use.
Sincerely,
David Kiamanesh
