Re: [ferret_users] MEMORY/SIZE= changes the result of SAVE

Hi Martin,

Thank you for your help.

First, I've found that if I trim my data a little bit, the problem goes away.  There seems to be a clear threshold.  When i=1:3600, the problem occurs.  If I save the i=31:3600 portion or the i=1:3500 portion of the data, the new datafile doesn't cause the problem.  Something like that.

That means that I have to debug the problem with this largish dataset.

That's brilliant!  Unfortunately, I haven't been able to generate a variable like that which reproduces my problem.  I confirm

1) "set data the_new_dummy_data.nc" ---The problem doesn't occur.

2) "set data my_problematic_data.nc" --- The problem occurs.

To repeat, the problem is

set data my_problematic_data.nc ! contains variable "usss"

set memory/size=300 !<--

let u = usss[d=1]

save . . . u[m=1:10@AVE]

save . . . usss[m=1:10@AVE]

The two datasets contains different values when th
