        Alex,
        Hello this is Jamie Uertz. How are you?
        I would suggest checking out this video on our website to ensure your darkfiled alignment is correct.
        After watching let us know if this helped and if you have any more questions!
        Thanks!
        Jamie

          Alex,
          Hello! Yes lines are normal as it is a line scanning system. Meaning a line of data ( 1 pixel row) is collected at a time. But these lines are pretty heavy. Meaning the signal to noise ratio is low on the image.
          What are you imaging? Can you send an optical picture of what you are trying to scan?
          This will help me.
          Thanks!
          Jamie

            Hello Alex! No, unfortunately the spectral range is set inside the spectrograph so subsetting the range will have to be done after the scan is complete. This can be done in the ENVI software.
            Thanks!

              If you have followed all the instructions for importing a spectral library and ran the SAM routine and the result is a blank window then that means that no spectra were identified as a match.
              Unfortunately there is no video for mapping 2 separate libraries, just the document at the top of this topic thread.
              Thank You,
              Jamie

                Hello! When you first open the Spectral Angle Mapper the “Endmember Collection” dialog opens like you posted on your screenshot. To load the first spectral library you must got to “Import” and then select “from spectral library file”
                This will load the first spectral library.
                Please see attached screenshot.
                Thank You!
