When I am using the 4band multispectral data for NDVI calculation, after successful completion of runtime, it shows some warning message like "loading 17%..."How could I rectify it? should I do any filtering for reducing the resolution effect before processed?

Thanks in advance.

If you have gdal command line setup you can try this:

gdal_translate -outsize xsize[%] ysize[%] <src_dataset> <dest_dataset>

Example: creating 25% of original image.

gdal_translate -otusize 25% 25% input.tif output.tif

......
