Dear FSLers,
I have two questions, and I would really appreciate if anyone could help me
out on this rather simple matter.
I compare 5 individuals that have done two slightly different experiments.
So far, I've done a FFX higher level, regional analysis of both
experiments. I rerun the higher level analysis with each of the eight
masks. I then extract the peak vxl from rendered_zstats (avwstats) and then
create a mask containing peak vxl and the 26 surrounding ones (avwmaths). I
then run featquery with that new mask to get mean BOLD % change.
I can't help thinking that this could be solved by running avwstats -x with
some kind of mask option and then create the 27 vxl ROI with avwmaths. Any
suggestions?
Also, is there any way of dilating a mask?
Best regards,
Benny Liberg
Instead of rerunning the higher analysis with new pre-thr masks applied
masks (8) for each anatomical strucuture, I would like to:
1. extract the peak vxl within a mask (avwstats) and
2. create a new mask containing 26 vxls around the peak vxl (avwmaths) and
extract mean %BOLD change from these 27 vxls.
I know how to do 1 and 2 but can't figure out how to avoid
