<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Dear Jennifer,<br>
<br>
Thank you so much for the help.<br>
1. I am trying to get HDF4.2r3, but look likes I cannot ftp the file, Here is what I did:<br>
***********<br>
<span class="code">ftp iges.org<br>
*********** <br>
Connected to iges.org.<br>
500 OOPS: cannot change directory:/web/colaftp<br>
ftp> <br>
<br>
Also, when I click" </span><a href="ftp://grads.iges.org/grads/Supplibs/2.1/src/HDF4.2r3.tar.gz">local copy of source code</a><span class="code">", it asks the name and passcode, I put "anynomous", it won't work.<br>
<br>
2. The Grads on my pc come with Ubuntu, so I guess it is not easy to change the default software. Do you know any version of Grads which can read hdf4, that way I can install it on my pc.<br>
<br>
Thanks again.<br>
<br>
Yalei<br>

<div>Your build is not enabled to handle hdf4 files, only hdf5. Please have a look at

<div>I believe the problem lies in your particular GrADS build, especially the hdf library. Can you send the output from 'q config'? </div>
