I tried the following but I always get the same error: OPENW: Filename argument must be a scalar string: FILE.

for i=0L, n-1 do begin
cgDisplay, 500, 550
Image = BYTSCL(Image, min=0.,max=160.)
cgimage,Reform(Image[i,*,*])
cgDrawVectors, REFORM(VX[i,*,*]), REFORM(VY[i,*,*]), pos_x, pos_y,VECCOLORS='yellow', /ORDERED, overplot = 1
write_gif,file, Reform(Image[i,*,*]), /multiple
endfor

write_gif, file, /close
