Plotting of Modis satellite data in HDF format using grads

[Jayakrishnan PR]

Dear All,
       I am now working in MODIS satellite data. The data is in HDF-SDS
format. I want to plot the data using grads, directly. Now I cannot plot the
data using gradshdf. I dont know the reason. I converted that data into
ascii and then I converted it into staion data, and using station grads I
have plotted the data. Now I can plot the colored map of each satellite pass
using station data.
      I am working in Linux platform ( ubuntu 6.1 version) with grads 1.9b4.


           Now my question is that can I plot the same data which is in hdf
format, directly in gradshdf..?. I have tried it but it dont worked. If it
is possible it will be a great thing for me because I can skip converting
into ascii, and then station format and plotting. I have heard the COARDS
convention for hdf data..? Is MODIS data following COARDS convention..?
            Any help is much appreciated....!!!!
                looking forward
