Hi,
I have performed a group analysis and can obtain a % BOLD value for a
selected voxel of interest using Featquery. I have read the Featquery page
and various emails on the FSL JISCmail but can not work out the answers to
these two questions:
1) How would I go about obtaining the individual values that make up the
mean % BOLD signal reported by Featquery? When I click on the “stats/pe1” I
think I only obtain the pe values for each of the participants. In fact
even if I click on “stats/varcope1” or “stats/tstats” or “stats/zstats” I
still obtain the same values as for “stats/pe1” which I think are the pe
values. Should this happen? I would have predicated that for example
clicking on “stats/zstat1” I would obtain the z values for each of my
participants.
2) With the “Convert PE/COPE values to %” option selected I get % BOLD
values that look about right. How do I go about getting a % varcope
associated with this % BOLD change? I can not work out how to convert the
reported stats/varcope1 value to a % varcope1.
I am running FSL version 3.3. I am grateful for any advice.
Best wishes,
Aziz.
