Re: [ferret_users] nc2mc.sh

[Patrick Jöckel <joeckel@xxxxxxxxxxxxxxxxx>]

Dear Yangxing Zheng,

nc2mc is a tcsh-script, it might be that you need to change
the first line from
#! /usr/bin/tcsh -f
into
#! /bin/tcsh -f
or another path.
You can check this with 'which tcsh' on your system.
Then 'chmod u+x nc2mc' and run it with "./nc2mc".

The list of files in this script is simply generated with
set list0 = `echo *$namefrag*.nc`, i.e., the order of files is determined by 
the way how the tc-shell  expands the '*'.
Something like 'find' or an additional sorting might be better suited ...

Now to your resulting mc-File:
The first stepfile-record seems to be OK (does it contain only 1 time step ?), 
all others are strange.

Four questions:
Does the time axis in all of your files have the same name ?
Is the time axis equidistant (and does it have the same unit ?) ? 
Which command line parameters did you apply (try 'nc2mc -h') ?

The first two 'yes' are prerequisites to make nc2mc work!

Can you provide the 'ncdump -c' of the first files in your list ?

Yours,

Patrick Joeckel
