It sounds like you could benefit from downloading the Hyperion Tools code writted by Devin White, and available on the Exelis VIS user contributed code library (http://www.exelisvis.com/language/e...ary.aspx). You can plug it into ENVI, and then call it from the ENVI menu. Just search for Hyperion and you'll see it at the top of the list of returned code. It has an option (Flag Mask Correction) that removes the vertical striping from Hyperion data. It also provides the option to create a mask for the malfunctioning detectors, that you can use in subsequent processing in ENVI, if you need to. - Peg

Hi Peg, I'm trying to use that Hyperion tool you mentioned but when I try to process an L1R file, I get an error message saying "average wavelength/FWHM/BBL file must be installed." Any idea what this is about and if that file has something to do with ENVI, the Hyperion tool, or something else? Thanks, Mike

Sorry, I figured that out myself...I forgot to put that other file in the save_add folder. Mike

Hi, Do you have any idea that after converting HDF Hyperion file in ENVI format, is there any need for further preprocessing? Have you done atmospheric corrections of your data, if so could you please help me as well as I am trying to get ths done but seems like making minor mistakes. It works well on embeded data of ENVI but for downloaded file I do not know how to do it. Will appriciate response from any one Roohi

Hi , I have followed the above procedures(I have downloaded and pasted Hyperion tools in the save_add folder), but I am not able to open Hyperion tools, I am not able to find Open External file option.. I am using Envi 5.1. Can anyone please suggest me how to open? Thank you

They Hyperion Tools will appear in ENVI Classic. When you start up ENVI 5.1, it brings up a newer interface. But ENVI Classic is still installed when you install ENVI 5.1, so you can get to it. On Windows, it will be under ENVI 5.1 > Tools in the Start Menu. Once it starts up, you will fine Open External File under the File item in the main ENVI Classic menu. Peg Exelis VIS

Thank you mam. I got it. Your helps a lot for dummies like us.

Hi, I have added hyperion tools plug in to the save_new folder. But I am not able to access hyperion or EO-1. I am using Envi 4.7 version. Please any one let me know how to use it.

The following files need to be placed in the c:\program files\exelis\enviXX\classic\save_add directory:

hyperion_tools.sav
hyperion_wl_fwhm_bbl.txt
flag_mask_settings.txt

When you start ENVI, the tools should be in File->Open External File->EO-1->Hyperion Tools.

The tools appear to be for ENVI 5.x so it might be that the 4.7 version is too old.
