On this, should I have at the beginning of my grads script open commands in single quotes for each of the 25 files I will be averaging, like I would at the command prompt? I'd imagine it would have to be done at some point for the script to use it.<br>

It sounds like you'll have to hard code the lat/lon boxes for each ave command then. Try something like<br>
<br>
lat1.1 = ...<br>
lat1.2 = ...<br>
.<br>
.<br>
.<br>
lat1.n = ...<br>
<br>
---<br>
<br>
lat2.1 = ...<br>
lat2.2 = ...<br>
.<br>
.<br>
.<br>
lat2.n = ...<br>
<br>
---<br>
<br>
lon1.1 = ...<br>
lon1.2 = ...<br>
.<br>
.<br>
.<br>
lon1.n = ...<br>
<br>
---<br>
<br>
lon2.1 = ...<br>
lon2.2 = ...<br>
.<br>
.<br>
.<br>
lon2.n = ...<br>
<br>
where lat1 and lat2 are the start and end latitudes of the box and lon1 and lon2 are th start and end longitudes of the box, and n is the number of files. Then do<br>
<br>
a = 1<br>
sum = 0<br>
while (a <= n)<br>
'd asum(field.'a',lon='lon1.a',lon='lon2.a',lat='lat1.a',lat='lat2.a')'<br>
*insert commands to take the output value into a new variable called summand<br>
sum = sum + summand<br>
a = a +1<br>
endwhile<br>
<br>
average = sum/n<br>
<br>
Is this what you are trying to do?<br>

Thank you for your response,<br>
<br>
The trouble is, I don't want the domains for each file to match. I have GRIB data that I have made ctl files for with
<a href="http://grib2ctl.pl" target="_blank">grib2ctl.pl</a> but I want to center each file (for a different day) on a different grid point and then average the files. Thus I wouldn't be averaging the same actual grid point in space each time.

<div>try opening them together<br>
<br>
open file.ctl<br>
open file2.ctl<br>
open file3.ctl<br>
.... etc<br>
<br>
then set the domain conditions (so that they all match)<br>
<br>
then just ave. Remember to call the variables with var.1, var.2 depending on the file number.<br>
<br>
if you give us an example of the commands you are trying to use we can probably help better<br>
<br>

<div>Is there a way to average several different files (presumably the same variable in each file) but with a different domain setting for each file?</div>
