<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

<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

<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>--
