Hi! I need to select multiple files from the ones already opened in ENVI. Some of the example on RSINC site use the ENVI_SELECT function as above envi_select, title='select images', /multiple, mfrs=mfrs, $ /no_spec, /no_dims, /file_only This example doesn't work on my ENVI 4.1 because MFRS is not allowed in ENVI_SELECT function. Also the "multiple" keyword is not documented on the ENVI help files (deprecated?). So how can i select multiple files? What function should i use? I need a function similar to the Basic Tools->Layer Stacking->Import Files... already present on my ENVI 4.1 environment. Thanks in advice!
