I am having a problem in creating new signatures in Signature Editor in ERDAS 2014. Whenever I click on the icon (i.e., after selecting the aoi), it shows an error which says "unable to open associated image: Image association may be edited with Edit menu (Image Association...)". After I had set the associated image from the edit menu of the Signature Editor and tried to create new signature, it displayed "Viewer image does not match associated image for signature set. Image association may be edited with Edit menu (Image Association...)". PLEASE HELP!!!
