There are 146 lines below the header. Sorry its not clear.
The lines from the counts files are created from an other file which contains 6,000,000 lines.
This file contains 6,000,000 sequences of length 146 with numbers 1,2,3, and 4.
I want to count the occurrences of all combinations of 1,2,3 and 4. So for example: 1 in position 1 in all sequences, and 3 in position 5 in all sequences.
So those counts are 146 x 146 matrices with counts of occurrences of all those possible combinations.
-------A=1,B=1-------
occurrences of 1 in one position and 1 in an other position
146x146 matrix
Hope its clear now...

NAME
envext - Extracts the envelope of a file to a text file. .
SYNTAX
envext [-flags] soundfile
csound -U envext [-flags] soundfile
INITIALIZATION
soundfile - Name of the input soundfile.
The following flags are available for envext (The default values are stated in parenthesis):
-o fnam Name of output filename (newenv)
-w size (in seconds) of analysis window (0.25)
The envext utility generates a text file containing time and amplitude pairs by finding the absolute peak within each window.
EXAMPLE
Using the command (while in the manual directory):
csound -U envext examples/mary.wav
will produce the a text file containing the following:
0.000 0.000
0.000 0.000
0.250 0.000
0.500 0.000
0.750 0.000
1.249 0.170
1.499 0.269
1.530 0.307
1.872 0.263
2.056 0.304
2.294 0.241
2.570 0.216
2.761 0.178
3.077 0.011
3.251 0.001
3.500 0.000
Which shows the time for the peak amplitude within each measured window.
