<DIV><BR></DIV>Hi Bob<BR> Should not matter where you put
them, check that the model.ctl file has the fist line looking like so:
<BR>dset ^model.grb<BR>and not pathed somewhere else, check the permissions on
teh files you need to at least be able to read them.<BR>Note that if you are
running grads from another directory than the one where the files reside you
bust give the absolute path to the control file, eg <BR><BR>ga> open /your
full path/model.ctl<BR><BR>Your directory holding the files should look
somthing like
so:<BR><BR>arabonis@baltic:/mnt/pacific/data/gradstut/atmosdata> ls
-lat<BR>total 593<BR>-rw-r--r-- 1 arabonis osis 593060 Jan 14 2003

<DIV>Thankyou, </DIV>
<DIV> </DIV>
<DIV>I have the datafiles all in the same directory. I have placed them in
the main Grads folder, and tried in just about every other folder too but I
still get the error. </DIV>
<DIV> </DIV>
<DIV>I can`t think of anything else to try!! I`ve been waiting to play
around with Grads for ages, but find this frustrating that I can`t even get
off the starting block :D </DIV>
<DIV> </DIV>
<DIV>Is there a specific place where the datafiles (ctl, grib) should go?

<DIV><BR></DIV>Hi Bob<BR> Welcome to grads, firstly I
feel that grads is better suited to the linux environment - besides being
basically anti-windows, you'll find a lot of the users of grads are
working in a unix/linux environment and user support is probably better in
that area, further for automation of grads scripts, linux is very flexible
(which seems to be your ultimate goal).<BR> It seems
though there have been some library issues with recent versions of grads
on certain flavours of linux, red hat does not seem to be one of
them but a trawl of the archives should resolve any
compatibility issues.<BR> With regard to load, thats
going to depend on your input files and what you do with them, however
grads is very stable and will generally complete the task without falling
over. I have grads running on an old 450 MHz P2 running scripts and it
works just fine.<BR> With regard to your problem with
the model file it seems to me to be a path problem, the data file and ctl
file must be in the same directory.<BR> Good
Luck<BR> Jean Pierre<BR>

<DIV>Hi all, </DIV>
<DIV> </DIV>
<DIV>I`ve never used Grads before, so it`s a completely new ball game
for me!! The most ambitious I`ve been is to use a desktop utility likes
DAWS! </DIV>
<DIV> </DIV>
<DIV>I have several questions to ask, where the answers could not be
found on the Cola homepage. </DIV>
<DIV> </DIV>
<DIV>I would like to install Grads on my server, mainly so I can ingest
and display grib data/model charts on my website. What kind of server
loads would I be looking at here? I need to know, whether my server can
cope with it it!! Can someone shed some light on using Grads on a redhat
linux based server? </DIV>
<DIV> </DIV>
<DIV>Secondly, I haven`t looked through any of the documentation as yet.
I thought it might be a good idea to install the windows version locally
on my W2K PC first, so I can get an idea of how Grads works. </DIV>
<DIV> </DIV>
<DIV>I believe I have it installed correctly, but I can`t even get off
the starting block!! I tried to open the demo model.ctl file that
comes with the online tutorial - all I get are errors `Scanning
description file: model<BR>Open Error: Can't open
description file` </DIV>
<DIV> </DIV>
<DIV>Do I need to place the ctl, grib and gmp in a certain folder? All
the tutorial says is download them and place them locally. Thanks.
</DIV>
<DIV> </DIV>
<DIV>Regards, </DIV>
<DIV>Ron. </DIV></BLOCKQUOTE><BR><PRE>--
