Hi Selvin,

I envy your 5 weeks of vacation!

the procedure I recommend is:

- start IDV
- under the 'File' or 'Data' dropdowns, select 'New Data Source'
- under 'New Data Source', select 'From the File System'

From there, navigate to a directory that has the file you want to look at; 
select
the file, and click the 'Add Source' button.  Then, if it is not already 
showing,
Click on the 'Data' dropdown and select 'Show Data Selector'.  From there choose
the field and type of display you want and then click on the 'Create Display'
button.

By the way, we need to get your IDV installation updated to the latest release,
v1.2.  This was released very recently, and it is most likely that you do
not have this version.  You can grab the new version by:

<as user 'idv'>

- registering as a Unidata user (if you havn't already) (create account on
  Unidata HomePage, http://www.unidata.ucar.edu)

- login to your account

- go to Downloads

- go to IDV

- download v1.2

Cheers,

Tom
