Hi, I'm a newbe of Envi.
I have to export a ROI complete dataset of Meris L2 images in Matlab.
I have create the ROI after georeferencing many images, I applayed the Roi to all images, and it works. I have the same ROI on all images.
Now I have to export the ROI data of each band (and mask) to a format Matlab-compatible.
Can someone help me? Thanks

One option would be to export the ROI as an ASCII text file from the ROI dialog.

Another option would be subsetting the ROI and saving as a normal ENVI file. Then to use Multibandread function in Matlab to read the ENVI file.
Hope this helps.

Thanks, it works!
Export in Ascii format is very simple and with a copy&paste you get data in matlab.
Multibandread works too, but I need to know in advance the number of rows... and I don't know how!!!

You will find all the parameters in ENVI header files!
