Hello Marwan,

 From looking at a fortran The CMORPH data files are flat (only data) 
files - the data are big-endian 4-byte floating point numbers.
You can read the data in to GrADS and process it as you like. You could 
also read the gridded data in Matlab using "fread" and extract or process
the data at the point of interest.

regards - Nick
