Hello ENVI UsersI am trying to run Image Change Workflow on two Regions of Interest. I am new to ENVI and learning to use it as part of my GIS certification.The Error Message reads: "The input files are incompatible. Only one input file is pixel-based"ContextThe first image is from the NHAP program, date September 9, 1985 The second image is from NAIP, dated: September 20, 2015 I used the ROI tool to select a section of the image. I saved and exported the shape. I used the shape to create a spatial subset of the main image. I am running the Image Change Workflow tool on the spatial subsets. Thanks in advance for any responses.Doug
