<html><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div><br></div>The reason that NCL cannot read anything useful in this file is that it contains no SDS (scientific datasets). All the data in this file is stored in Vdata datasets. These are spreadsheet-like entities with records consisting of multiple named fields where each field can have its own type and number of elements. Without significant new development of the NCL interface to HDF4, NCL has no capability to read files like this one. In other words, this is not a bug at least with respect to NCL itself.<div><br></div><div>However, the error message emitted by ncl_convert2nc is confusing to say the least. Since ncl_filedump is able to print out the global attributes, it seems that ncl_convert2nc should at least put out a file with the attributes, along with a message that no readable variables could be found in the file. I will file a ticket for this problem.</div><div> -dave</div><div><div><br></div><div><br><div><div>On Sep 13, 2010, at 2:49 PM, SMITH, JONATHAN WYNN.
