If the scale_factor attribute is not defined properly in your data file, you can try to fix it using one of the stand-alone utilities in the HDF library. Setting the scale factor to a fixed number globally at the desriptor file level will likely cause problems
for other variables in the file that may not share the same attribute value � that is why you give the name, and then the attribute is retrieved for each individual variable in the file. If you can�t repair the formatting of the data file, then you only option
is to use the scale factor whenever you want to display the variable, e.g.
<div>ga-> d var*0.1</div>
<div>�Jennifer</div>

Hi,<br>
<br>
I used unpack (to unpack byte data-variable) in my ctl to display hdf-eos files. But, some files giving errors:<br>
<br>
Warning: HDF attribute named "scale_factor" has more than one value<br>
Warning: Could not retrieve "scale_factor" -- setting to 1.0<br>
Warning: HDF attribute named "add_offset" has more than one value<br>
Warning: Could not retrieve "add_offset" -- setting to 0.0<br>
Contouring: 0 to 60 interval 5 <br>
<br>
It does not reads the scale_factor and add_offset. It seems they are not defined properly in the data file:<br>
<br>
varx:scale_factor = "0.1<br>
varx:scale_factor_er = "0<br>
varx:add_offset = "0<br>
<br>
It should have been float.<br>
<br>
As, by default Grads sets the scale factor to 1.0, how can I change/force the same to 0.1 (inside ctl)?<br>
<br>
Regards and Thanks,<br>
Mahakur<br>
