Hi. I have a problem rewriting the data to the original hdf file
(i.e., to the same dataset which i had read from, earlier) I am
getting negetive data values. Also I am getting the same negetive data
values if i put a dummy array instead of the data in the
HDF_SD_ADDDATA command. I got correct values when I output the result
to a tiff file, but not able to get the correct values if I write it
back to the original file. I have posted my code bellow. Can anybody
please help me with a solution

sdFileID2 = HDF_SD_Start(fname, /RdWr)
sdsIDsm = HDF_SD_Select(sdFileID2,im[j]); im[j] are different bands
HDF_SD_ADDDATA, sdsIDsm, rowp, start=[0,0], count=[x[j],y[j]]
; rowp is the dataset and is of type float
; x,y are the array dimensions
HDF_SD_EndAccess, sdsIDsm

Thank you

Rajesh
