~/Mfiles/ume/

This is a first draft at a simple way of browsing HIS .ume data files
(100 word header) in MATLAB.

The two main functions are umereader.m and umebrowser.m.  umereader
loads in data from a .ume file and puts the results into a structure
(i.e. 'his').  The field names of this structure are defined
explicitly for use with umebrowser.  umebrowser uses the structure and
provides a simple point and click browse of the data.  Additional 
documentation can be found within the code itself.  The other *.m
files are used within umereader and umebrowser.

All of the files in the edittools toolbox are also needed for
umebrowser.  This directory (edittools/) is added to the matlab path
upon startup in startup.m.

After downloading these files (including what's in edittools/), start
MATLAB and at the prompt type:

>> his = umereader; 

and use the gui to pick out a .ume file, or if you already know the
filename, just enter it directly (i.e. his = umereader('930919.ume');)
To see the fields of the structure his, simply type 

>> his

To plot the first spectrum, type

>> plot(his.freq,his.rad(1,:))

or to start the browser,

>> umebrowser(his)

or, to combine these tow commands,

>> umebrowser(umereader)

For help with any of the functions, type i.e. "help umebrowser" at the
MATLAB prompt.  Some known bugs/limitations/features are listed at the
beginning of each m-file.  I've done only minimal testing on this
package so it comes with the usual disclaimer.
questions/bugs/comments, please contact dave.tobin@ssec.wisc.edu
