ROI stack [message #60816]

Hello,
Can anyone see where I'm going wrong here? I'm trying to generate a
binary mask of a multislice MRI image. When I run this at the
command line it works, but when I put it in a loop, it fails to return
anything. i.e. all variables of interest are "undefined"
Any help/tips would be appreciated!
Thanks,
Megan
AT COMMAND LINE:
xroi, img[*,*,i], regions_out = roi, /Block
mask = roi -> ComputeMask(Dimensions = dims, Mask_Rule=2)
masks[*,*,i] = mask
LOOP:
pro twodmask
img = read_nifti(dialog_pickfile())
dims = size(img[*,*,3], /dimensions)
s = size(img, /dimensions)
n_slices = 2 ;s[2]
masks = fltarr(dims[0], dims[1], s[2])
for i = 0,n_slices-1 do begin
xroi, img[*,*,i], regions_out = roi, /Block
mask = roi -> ComputeMask(Dimensions = dims, Mask_Rule=2)
masks[*,*,i] = mask
endfor

end
