Frequency of each character
My bad, l guess I did not express myself correctly. From my previous example:
Quote:
> Seq1 Freq 1
ATC
> Seq2 Freq 33
ACG
> Seq3 Freq 33
TTG
> Seq4 Freq 33
TCC
The first character in the first sequence is A, and the frequency of that sequence is 1%. However, A is also present in the same position (1) in sequence #2 and the frequency of that second sequence is 33%. Therefore, the 'global' frequency of A in the data set in position 1 is = 34%, hence it should be kept. When you do the same for the second and thrid position you can see that the global frequency for T (second character) and C (third character) from Sequence 1, are =34%, and therfore that should be enought to keep the entire sequence.
I hope I have better explain what I would like to accomplish.
Thanks one more time!

Tcl_Backslash(3) Tcl Library Procedures Tcl_Backslash(3)
__________________________________________________________________________________________________________________________________________________
NAME
Tcl_Backslash - parse a backslash sequence
SYNOPSIS
#include <tcl.h>
char
Tcl_Backslash(src, countPtr)
ARGUMENTS
char *src (in) Pointer to a string starting with a backslash.
int *countPtr (out) If countPtr is not NULL, *countPtr gets filled in with number of characters in the backslash sequence, includ-
ing the backslash character.
_________________________________________________________________
DESCRIPTION
The use of Tcl_Backslash is deprecated in favor of Tcl_UtfBackslash.
This is a utility procedure provided for backwards compatibility with non-internationalized Tcl extensions. It parses a backslash sequence
and returns the low byte of the Unicode character corresponding to the sequence. Tcl_Backslash modifies *countPtr to contain the number of
characters in the backslash sequence.
See the Tcl manual entry for information on the valid backslash sequences. All of the sequences described in the Tcl manual entry are sup-
ported by Tcl_Backslash.
