A fresh look into the problem revealed: ENVI> Raster = e.OpenRaster(inFile) % Loaded DLM: NATIVE. ENVI> fid = ENVIRasterToFID(Raster) ENVI> envi_file_query, fid, bnames=tellme ENVI> print, tellme Mean: Elevation - Minimum Mean: Absolute Roughness Mean: Local Roughness Mean: Slope (degrees) Mean: Point Density Variance: Elevation - Minimum Variance: Absolute Roughness Variance: Local Roughness Variance: Slope (degrees) Variance: Point Density Homogeneity: Elevation - Minimum Homogeneity: Absolute Roughness Homogeneity: Local Roughness Homogeneity: Slope (degrees) Homogeneity: Point Density Contrast: Elevation - Minimum Contrast: Absolute Roughness Contrast: Local Roughness Contrast: Slope (degrees) Contrast: Point Density ENVI> does the trick.

If you are trying to access the band names, it is part of the metadata for the raster. For example: ENVI> file = 'C:\TEMP\qb_boulder_msi.dat' ENVI> raster = e.openraster(file) ENVI> print, raster.metadata ENVIRASTERMETADATA BAND NAMES = 'Band 1', 'Band 2', 'Band 3', 'Band 4' DATA GAIN VALUES = 0.30000000, 0.20000000, 0.50000000, 0.40000000 DATA OFFSET VALUES = 0.00000000, 0.00000000, 0.00000000, 0.00000000 DESCRIPTION = 'Demo QuickBird 2 data courtesy DigitalGlobe', 'Inc. Not for commercial use.' SENSOR TYPE = 'QuickBird' WAVELENGTH = 485.00000, 560.00000, 660.00000, 830.00000 WAVELENGTH UNITS = 'Nanometers' ENVI> bnames=raster.metadata["band names"] ENVI> print, bnames Band 1 Band 2 Band 3 Band 4 ENVI> help, bnames BNAMES STRING = Array[4]
