The following shows how the data were exported to ASCII
files from the "wera" struct array.

Export Data

>> fid=fopen('wera_U.txt','w');
>> fprintf(fid,'%8.4f\n',wera.U);
>> fclose(fid)

Note:
wera_U.txt contains a single column.  For where and when,
see wera_x.txt, wera_y.txt, and wera_t.txt, respectively.
The wera.U three-dimensional array was written out as
1. the first 14 lines in the file are
   row 1-14, 1st column, 1st time, ie., wera.U(1:14,1,1) 
2. the next 14 lines in the file are
   row 1-14, 2nd column, 1st time, ie., wera.U(1:14,2,1) 
3. this repeated until all columns for time=1 was completed
4. then it repeats again, wera.U(1:14,1,2), now for second time, etc.

Next,
repeat, the fopen, fprintf for each data array in struct array "wera".

Note:
>> fid=fopen('wera_x.txt','w');
>> fprintf(fid,'%11.6f\n',wera.x);
>> fclose(fid);

(similar for wera_y)

Note:
for time, wera.t, stored as Serial date number.
    Date numbers are serial days where 1 corresponds to 1-Jan-0000.

convert to year, month, day, hour, min, sec
>> dtg=datevec(wera.t);
