hi, i'm trying to render my func data so it can be overlaid onto my high
resolution structural image. it seemed to have worked for one contrast
(based on what was outputted into my hr directory) but then in the terminal
from where i launched the renderhighres_gui, i got a bunch of error messages
that read: ERROR:: Empty mask image.
when i overlay all but one of the hr/rendered_*.nii.gz onto my
hr/background.nii.gz everything turns RED?
the mask in the hr directory, masknz.nii.gz, when viewed in fslview is empty
but it does have a file size of 751?
also, the mask in my feat directory, mask.nii.gz looks like a normal mask in
fslview, but here too, the masknz.nii.gz seems to be empty.
any thoughts? could it be my threshold is too high? but in my feat report
there are voxels that survive thresholding...
thanks!
