Malcolm, Thank you for the unusual sample data file! I've converted part of the BUFR file you sent me to XML, using sourceforge.net/projects/wmobufr. Each BUFR subset becomes one XML file. So far I've decoded the first 156818 subsets, taking up over 6 GB (that's gigabytes!) of disk space. What on earth is in that file? I'm guessing it's a compendium. It might be easier to deal with as separate BUFR files. Anyway, there doesn't seem to be anything wrong with your file (at least for the first 156818 subsets), aside from the unwieldy size. I didn't see any problems with long bit values. Steve On Tue, Nov 18, 2008 at 01:47:25PM +0100, Malcolm Mistry wrote:
Hello! I am trying to plot a bufr file in Grads and for this I require to use Grad's 'bufrscan' utility to create a .ctl file (for Grads). (bufrscan basically gives the header & body information of bufr file to create a descriptor file for plotting in Grads) When I run the bufrscan utility, initially I got errors (such as "unable to find B3M-000-012-B table"). I have corrected this by downloading the latest tables. So now bufrscan runs correctly and checks the bufr file. However, it gives me a segmentation fault (below is a part of the output). ---------------------------------------------------------------------- warning: can't read 80-bit data value; max is 32 warning: can't read 256-bit data value; max is 32 warning: can't read 256-bit data value; max is 32 warning: can't read 192-bit data value; max is 32 warning: can't read 80-bit data value; max is 32 warning: can't read 256-bit data value; max is 32 warning: can't read 256-bit data value; max is 32 warning: can't read 192-bit data value; max is 32 warning: can't read 80-bit data value; max is 32 Segmentation fault ---------------------------------------------------------------------- I suppose the problem is the machines where i try to read this bufr file is not able to handle the max bit size (of the data) in the bufr file. I have tried to figure out where the max bit size is defined in the tables (B, D etc)...but am unable to solve this. I have tried running this on both 32 & 64 bit machines but get the same error (i suppose thats because it needs 256 bits). I was wondering if there is anyways to solve this problem (may be increase the max bit in the tables) Hoping someone can help me out.
