I guess it happened because you haven't split the gmapsupp.img --which I forgot to mention in my previous post.
To do that, you go to Split tab, and then choose Create single maps.
It will split into several img files.
From there, you pick the img file that contains the area of your interest.
And then you can proceed according to my previous guide.
Before All!!! You know the handbook Modis GPP?
Now. What do you want to do with your data for an annual time series? and sorted by months?
the image that you download is a composite of the maximum value of GPP for that period, which should be added month by month as appropriate!!
Tell me! What do think about this now.
Thank you very much for your kind and clear guide.
I'm trying to convert an img (NT).
First thing: the split result is aabout 22o GMP files!!
Second: each GMP contains only .TRE .RGN .LBL (missing, .NET, .NOD,).
Are these three enough for the further joining in GMAP Tool?
Is there a way to use Garmin-GMP-extractor with multiple GMP at once?
