Hi Massoud,

No worries.

Very good.  Please be aware that you (your lab) will have to join
the McIDAS Users Group (MUG) in order to get McIDAS from SSEC, and
this is not free.

Actually, the part of the pattern/action to edit is the regular expression.
The easiest way to see what to do is:

- use the LDM 'notifyme' utility to list out the FNEXRAD products you are
  receiving and look at the headers

- create a regular expression that matches the header of the product(s)
  you want to process

- test your regular expression using the '-p' flag on 'notifyme'

- once you have a regular expression that selectes the product(s) you
  are interested in, use it as a replacement for an existing pattern
  in your pqact.conf file (or create a new action)

Here is an example of me running 'notifyme' to an upstream host
that is receiving all FNEXRAD products:

1) use 'notifyme' to list out the FNEXRAD headers:

$ notifyme -vxl- -f FNEXRAD -h oliver.unidata.ucar.edu -o 3600

2) the pattern action you have currently is:

# png compressed 1km radar GINI format
FNEXRAD ^rad/NEXRCOMP/(...)/(...)_(........)_(....)
 FILE   -close  data/gempak/images/sat/NEXRCOMP/\1/\2/\2_\3_\4

   Take a look at the pattern specified in comparison to the product
   headers:

^rad/NEXRCOMP/(...)/(...)_(........)_(....)

rad/NEXRCOMP/1km/n0r_20070704_2211
rad/NEXRCOMP/4km/ntp_20070704_2212
rad/NEXRCOMP/2km/n1p_20070704_2214

  The portion of the pattern that matches the product resolution
  is the first '(...)'.  So, if instead of specifying the pattern
  as '(...), you use '(1km)', your revised pattern will be:

^rad/NEXRCOMP/(1km)/(...)_(........)_(....)

3) to verify that this pattern will select only the products you are
   interested in, use 'notifyme' again this tiime specifying a pattern:

   Notice that the only products listed are the 1km n0r compsites, the ones you 
want.

4) modify your pqact.conf pattern to be:

# png compressed 1km radar GINI format
FNEXRAD ^rad/NEXRCOMP/(1km)/(...)_(........)_(....)
   FILE -close data/gempak/images/sat/NEXRCOMP/\1/\2/\2_\3_\4

5) run 'ldmadmin pqactcheck' to verify that you did not make any typos

6) as soon as 'ldmadmin pqactcheck' shows no errors, send a HUP signal to
   pqact:

   ldmadmin pqactHUP

And you are done.

Cheers,

Tom
