Uploading PEPP
Data Files to Princeton
There are several
options for uploading files to the Princeton PEPP website, including direct
ftp, ftp embedded in a web browser (Netscape or Internet Explorer),
and using an independent file transfer program such as Fetch.
The file to upload must be in PEPP
format (which is automatic if you are running QUAKES). If running SCREAM,
you are probably recording in GCF format, which must be converted to PEPP
by using GCFInfo.
Using Netscape ftp
If you have a
file to upload to Princeton, it is easy to use NETSCAPE
ftp. I have found that this method works from school, where we have a "firewall"
that does not allow the use of an outside ftp program like Fetch.
Open NETSCAPE or Internet
Explorer. Go to this address: ftp://lasker.princeton.edu/pub/SDU.
If you are using the computer you will always use for uploading data, Bookmark
this address; in the future you won't have to type it in again.
Go to the File menu. Select
Upload File. You will be asked for the location of the data file
you wish to upload. Scroll to Desktop. Open the floppy. Highlight
your file.
Within a few seconds, your file
will be uploaded, and you should see it on the Princeton list.
If the file does not upload properly,
change the title of the disk holding the data to something like "PEPP
Data". The SDU directory may then recognize the file.
Using Fetch
A second way to
upload data files is to use an outside file transfer program, such as Fetch.
It works easily, but may be blocked if your school system has an imposed "Firewall"
to the outside world.
The first time you use Fetch, you
will have to enter some information, which can be saved for the future as
a shortcut.
For Host, type lasker.princeton.edu
For User ID, type anonymous
For Password, type your
e-mail address
For Directory, type pub/SDU
Click OK
To save these parameters as a shortcut,
select Customize, then New Shortcut. The information will be
on the screen, so just select OK.
You can now choose your file for
upload. Make sure Binary is selected at the lower right, and then select
Put File. Select the file location (probably Desktop or 3.5 floppy),
then select the data to upload. Fetch will take care of the rest!
A PC can use direct ftp. Click
on Start, then Run. Type in ftp lasker.princeton.edu
, then hit Return.
Using FTP
The most "primitive"
way to transfer files, but sometimes the most efficient when transferring
a large number of files, is using the DOS-based program FTP. The easiest
way to start FTP from a Windows-based machine is from the "Start"
menu on the taskbar. Use your mouse to select "RUN", and
then enter "ftp lasker.princeton.edu" in the box. A DOS
window will open up on your screen. After the program connects to
the Princeton computer, you will be prompted for a user name: enter
anonymous; when prompted for a password, enter your email address.
You should get a response that
looks like the following:
230
Guest login ok, access restrictions apply.
Remote system type is UNIX.
Using binary mode
to transfer files.
ftp>
This shows that you are logged
in to the Princeton computer. You will need to change to the upload directory.
At the ftp> prompt, enter the command:
cd
pub/SDU
To ensure that the files will
be transferred in binary (not ascii) mode, enter the command:
bin
Finally, to transfer your files,
type:
put
filename
or,
for multiple files
mput
*.*
and
you will be prompted as to whether you want to transfer files, one by one.
Note that ftp will only transfer the files from the directory
from which ftp was started (often C:\Windows). Assuming that
the files are in a different directory, you have several choices:
(1) Enter the full path for the
file, e.g.:
put
C:/PEPP/Data/9908072300Z.DAT
or
put
A:/9908072300Z.DAT
or
mput
C:/PEPP/Data/*.DAT
(2) Change your "local" directory within ftp, by issuing a command
of the form:
lcd
C:\PEPP\Data
When all files
have been transferred, type quit to end your ftp session.
