Re: [ferret_users] **ERROR: inconsistent sizes of data regions: X axis



Oh --- one more thing.


At the ferret documentation page:

http://ferret.pmel.noaa.gov/Ferret/Documentation/Users_Guide/current/fer_html.htm

The left panel index has a list for "divergence". When I click on this, I am sent to Ch3 Sec2.4.16. @DDCcentered derivative. But the word "divegence" doesn't appear anywhere
in Ch3. Maybe this is a messed up link?

I am calculating the divergence from U and V:

use U_p.f30.100c_br1.cam2.h1.0350_0369-05-01_10-31_emean.nc
use "../../f30.101a_br1/stats/U_p.f30.101a_br1.cam2.h1.0250_0269-05-01_10-31_emean.nc"
let au = 'U'[d=2]-'U'[d=1]

use V_p.f30.100c_br1.cam2.h1.0350_0369-05-01_10-31_emean.nc
use "../../f30.101a_br1/stats/V_p.f30.101a_br1.cam2.h1.0250_0269-05-01_10-31_emean.nc"
let av = 'V'[d=4]-'V'[d=3]

let div = au[i=1:128@ddc] + av[j=1:64@ddc]


I can plot the entire field:

fill div[k=1,l=1]

But if I try to plot a sub-region:


fill div[x=-30:60,y=-20:40,k=1,l=1]


I am told:

**ERROR: inconsistent sizes of data regions: X axis
AV[J=1:64@DDC] has 11 points (I=118:128)
expression has 128 points (I=001:128)


I'm not sure what to make of this. Any suggestions?

Thanks

Bob
