I am doing time series analysis using Sentinel 2 data to look at NDVI change over time. The sentinel images include the date within the filename structure and I would like to pull this through to be in the output filename. However in envi modeler, the output filename is based on task and using the iterator it just gives NDVI 1,NDVI 2 etc with no link to the input filename and importantly the date within it. Anyone able to help on this?
