I have been trying for a long time with graph builder with no success. I tried to read an image and calculate the NDVI and write it but an error appears “Unable to find band that could be used as red input band” and the box to select the bands in DVI tab is empty. I tried with Sentinel-2 L1C and L2A products, with full product or single tiles, with .xml and single jp2 bands, and no way. I also tried to reinstall Anaconda and SNAP but it didn’t work neither. This same process works without problems using the command window, but I would like to do batch processing based on a simple processing graph like that.
Any suggestion? Thanks
