11    
12     The MITgcm has several packages that are related to the output
13     produced during a model integration that is used for analysis
14     of the results. The packages are related to the choice of output
15     fields and to the format of the model output.

33     \section{Pre- and Post- Processing Scripts and Utilities}
34    
35 adcroft 1.3 There are numerous tools for pre-processing data, converting model
36     output and analysis written in Matlab, fortran (f77 and f90) and perl.
37     As yet they remain undocumented although many are self-documenting
38     (Matlab routines have "help" written into them).
39    
40     Here we'll summarize what is available but this is an ever growing resource
41     so this may not cover everything that is out there:
42    
43 molod 1.8 \subsection{Utilities supplied with the model}
44 adcroft 1.3
45     We supply some basic scripts with the model to facilitate conversion or reading
46     of data into analysis software.
47    
48 molod 1.8 \subsubsection{utils/scripts}
49 adcroft 1.3
50 adcroft 1.4 In the directory {\em utils/scripts} you will find {\em joinds} and {\em joinmds}:
51 adcroft 1.3 these are perl scripts used from joining the multi-part files created by
52     MITgcm. {\bf Use {\em joinmds} always}. You will only need {\em joinds} if you
53     are working with output older than two years (prior to c23).
54    
55 molod 1.8 \subsubsection{utils/matlab}
56 adcroft 1.3
57     In the directory {\em utils/matlab} you will find several Matlab scripts
58     (.m or dot-em files). The priniciple script is {\em rdmds.m} used for reading
59     the multi-part model output files in to matlab. Place the scripts in your
60     matlab path or change the path appropriately, then at the matlab prompt type:
61     \begin{verbatim}
62     >> help rdmds
63     \end{verbatim}
64     to get help on how to use rdmds.
65    
66     Another useful script scans the terminal output file for "monitor" information.
67    
68     Most other scripts are for working in the curvilinear coordinate systems which
69     as yet are unpublished and undocumented.
70    
71 molod 1.8 \subsection{Pre-processing software}
72 adcroft 1.3
73     There is a suite of pre-processing software for intepolating bathymetry
74     and forcing data, written by Adcroft and Biastoch. At some point,
75     these will be made available for download. If you are in need of such
76     software, contact one of them.
