Hello,I just submitted a tech support ticket for this, but I thought I share this here too...I was very happy to see that class names and colors can be easily edited now in ENVI 5.3, but it looks like it's not quite working right yet. The steps below explain my workflow that resulted in some unwanted results:1. I did a very simple K-means classification of a Landsat 6-band subset, which worked fine.2. I edited class names and colors by right-clicking the 'Classes' and did my color and names edits, which worked too.3. I noticed in the Data Manager that the file information loses all the projection and some other info - not good.It seems to be that this might be a bug, so I wonder if others experienced something similar. My workaround for now would be to do the classification and save its header file under a different name. Then do all the class edits, which removes some important header info after the edits are saved. From the header that was edited, I then copy/paste the updated class color and name info into the original header and rename it again to use it with the file. Fairly easy workaround that way, but of course it'd be better if none of the header info is lost in the first place.MikeMike
