[seek-dev] RE: pgm_cut program

[Bing Zhu]

David,

I am glad that the SRB implementation works fine in getting partial images
for Niche
Modeling pgm data.

This is a good step. I just had a meeting with Raja discussing about moving
this approach to our Ecogrid. Raja suggested to modify the SRB code in
Ecogrid
node to handle the parameters currently implemented in pgm_cut.

With this approach, the URL used by Niche Modeling in calling our Ecogrid's
'get' function
to retrieve partial pgm image will have the syntax similar to a cgi request.
e.g.
  $ java org.ecoinformatics.ecogrid.client.EcogridQueryClient get  \

srb://../home/whywhere/.../n00an1.10.pgm?left=10&top=10&width=25&height=30 \

http://orion.sdsc.edu:8080/ogsa/services/org/ecoinformatics/ecogrid/EcoGridL
evelI

One of my next tasks in SEEK will be modify the SEEK SRB code to handle this
for Niche Modeling data. And this approach is also applicable for other
applications which
request partial data transfer.

Hi, Bing,
   Thanks for your help. I've just tried the program and it worked well.
But, I don't understand the need to use S-command. I just copied pgm_cut to
my local directory on landscape and it worked even if I don't copy the
S-command directory. By the way, if I want to rebuild the program on
Windows, do I need to download the whole directory of SRB1.2.1?

                                                          Thanks,

                                                          Haowei

Hi Haowei,

I changed the permission for some directories and files.
Please try it again and let me know if the permission problem still
exists.

The files are in the directory, /export/home/bzhu/pgm_cut.

You might also need to use SRB software which is installed in
/export/home/bzhu/SRB2.1.2. Basically, you just need to use
SRB client programs, S-commands, which can be found
in /export/home/bzhu/SRB2.1.2/utilities/bin. To use them, you need
an SRB account. Currently we can use the user, 'whywhere'.
I will be glad to show you how to use SRB software so that
you can test the software with different pgm files stored
under 'whywhere'.

Sincerely,
Bing

Hi, Bing:
   I will test the new version of pgm_cut, but I don't have the permission
to access the directory. Is it possible for you to mail me pgm_cut?

                                                    Thanks,

                                                    Haowei

David,

I modified the pgm_cut.c code to read pgm files stored in SRB storage place.

The modified pgm_cut.c can be found in the directory,
/export/home/bzhu/pgm_cut,
in landscape machine.

Here is an example of running 'pgm_cut' to get partial image from a pgm file
in SRB.

 $ pgm_cut 0 0 20 20 /home/whywhere.seek/ei/Data/Terrestrial/n00an1.10.pgm

Note that I have re-uploaded whywhere data using a new SRB account,
'whywhere',
as we discussed last time. The new uploaded data, along with their metadata,
is in the collection, /home/whywhere.seek/ei/Data/Terrestrial.

Here is the whywhere account info.
user name: whywhere
password: I will send you in another mail.
SRB server: srb.sdsc.edu
SRB domain: seek
SRB port: 6613

I'd like to test it next Monday. Will you be in office next Monday?

Sincerely,
Bing
