Hi Doug and Freesurfers,
I am currently analyzing data acquired from the Sternberg memory
task, which involves memorizing sets of 1, 3, 5, and 7 letters. I
have created an analysis (see attached analysis.info and paradigm
example) which allows me to create maps of the load-based activation
when going from 1 to 3 to 5 to 7 letters, which accounts for the
analysis' single "contrast".
My PI was hoping that, for some subjects, we could look at the
regression from JUST 1 to 3 to 5, since they have poor 7-letter data.
>From looking at the analysis setup, it looks like I would have to
make this change at the paradigm level since subjects have already
been run with the current analysis with just the 1,3,5,7 regression
contrast. I would probably have to change the "2"s in the paradigm
file to "1"s for the 7-letter sets (since the contrast is 2vFix, and
this alteration would essentially "ignore" the 7-letter condition),
but a change at the paradigm file level, I believe, would essentially
necessitate the formation of a new analysis entirely, which would
then have to be run again individually on subjects, which can be a
time consuming process.
I was wondering if there was a way I could bypass this step and
modify the analysis to suit these newer needs, or will I have to
essentially make a new analysis based on my current one for this to
work?Thanks, Adam Nitenson, B.S. Brain Genomics Lab Massachusetts General Hospital niten...@nmr.mgh.harvard.edu Phone: 617-643-3215
