I just did it; I suppose this is what you mean:

pro veamos, event
;
; Choose the bhtmref.img file
;
ENVI
ENVI_SELECT, fid=fid
;
; Get the dimensions for this
; file and create an ROI
;
ENVI_FILE_QUERY, fid, dims=dims
roi_id = ENVI_CREATE_ROI(ns=ns, nl=nl, $
color=4, name='Square')
;
; Define the square and add
; the polygon object to the ROI
;
xpts = [100, 200, 200, 100, 100]
ypts = [100, 100, 200, 200, 100]
ENVI_DEFINE_ROI, roi_id, /polygon, $
xpts=xpts, ypts=ypts

ENVI_SAVE_ROIS, 'Square.roi', roi_id

end

but it still keeps giving the same error.

Thanks anyway, for your response.

Jose
