Hi,
I am new to IDl and new to to this great group. Would be obliged if
anybody can help me with my programming problem.
My program tries to do some simple data manipulation. There are say 3
binary data files [FILE1, FILE2, FILE3] and I have to put them into
one big file where, the big file[FILE_NEW] contains 3 columns[for
three binary files] and the rows of these files come under the columns
of FILE_NEW [after transposed].
Now, when I try to run the program, as shown below, it get stuck with
the listed errors below when i=46, i.e. when (i*720-1)=33119 in FILE1
of first line within the loop. ### The program worked and gave
expected results when the data dimension was less, say for binary
files of [115][100] ###
Just can't guess why it is so. Please help !!
-----------------The Program :start------------------
pro data_stacker_big1
FILE1 = read_binary('feb_2001_geo5.bsq', DATA_DIMS=[720,356])
FILE2 = read_binary('mar_2001_geo5.bsq', DATA_DIMS=[720,356])
FILE3 = read_binary('apr_2001_geo5.bsq', DATA_DIMS=[720,356])
;Below 256320 = 720*356
FILE_NEW=bytarr(3,256320)
for i=1,356 do begin
FILE_NEW[0,((i-1)*720):(i*720-1)]=FILE1[((i-1)*720):(i*720-1 )]
FILE_NEW[1,((i-1)*720):(i*720-1)]=FILE2[((i-1)*720):(i*720-1 )]
FILE_NEW[2,((i-1)*720):(i*720-1)]=FILE3[((i-1)*720):(i*720-1 )]
endfor
openw, lun, 'output.dat', /get_lun
printf, lun, FILE_NEW
free_lun, lun
end
-----------------The Program :end------------------
-----------------Error Message while running :start------------------
IDL> data_stacker_big1
