Hi, I downloade the pyhdf-0.9.0 and install it. Then I did: from pyhdf.SD import SD, SDC and I had: Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: No module named pyhdf.SD I have a script to read and plot MODIS data and it use the from pyhdf.SD import SD, SDC. What do I do to solve this? Thanks, Conrado
