Dear SPM users,
I have a question regarding changing the voxel size.
I have fmri data which I want to analyze with a manually traced anatomical
mask (on a t1). In order to use this mask I want to analyze the data in native
space. After realigning and slice-time correction I coregistered the EPI's to the
T1, and resliced them to use as input for my design. This reslice option
interpolates the EPI however to the 1x1x1 voxel size of the T1 template,
thereby leading to an explosion of my data (as I have 1500 epi's per subject
and 70 subjects). Is it possible to reduce the voxel-size again, or does anyone
has another good suggestion to do this analysis? I already tried coregistering
the T1 and the mask to the epi, but this grossly distorts the masks.
Thanks in advance,
