Dear friends,
please tell me how to pass the external variable values to the nawk command.
length=`expr $len2 - $len1`
i need to pass $length to following nawk command as mentioned below.
nawk '{if((x=index($0,"W/X"))>0){id=substr($0,x, $length);print x;print id;}}' filename1
but I am... (1 Reply)

Hi
Running a specific nawk statement over a 17m lines files returns the following:
/bin/nawk: not enough args in .....
input record number 1,25955e+06, file test.1
source line number 1
I'd like to report the line number (in bold above) in decimal not floating so that i can spot it out.

Hi,
I am currently filtering a file that has multiple sets of data. An example of some of the data is as follows;

I want to remove all rows with a minor repeating count less than 30% compared to the major repeating count from my table. The values of a col(starting col 2) can assume is A,T,G,C and N. Each row has at least 2 values and at most 4 repeating values(out of ATGC).
N is considered a missing value... (12 Replies)

Hi, is there a faster/simpler way to filter values from the variable1 in variable2?
example:
variable1="A|B|C|E"
variable2="A|B|C|D|F"
output: "A|B|C"
Thanks,

I am trying to filter a big file with several columns using values on a column with values like (AC=5;AN=10;SF=341,377,517,643,662;VRT=1). I wont to filter the data based on SF= values that are (bigger than 400)

slagv2
slagv2.f(3) LAPACK slagv2.f(3) NAME
slagv2.f - SYNOPSIS
Functions/Subroutines subroutine slagv2 (A, LDA, B, LDB, ALPHAR, ALPHAI, BETA, CSL, SNL, CSR, SNR) SLAGV2 Function/Subroutine Documentation subroutine slagv2 (real, dimension( lda, * )A, integerLDA, real, dimension( ldb, * )B, integerLDB, real, dimension( 2 )ALPHAR, real, dimension( 2 )ALPHAI, real, dimension( 2 )BETA, realCSL, realSNL, realCSR, realSNR) SLAGV2 Purpose: SLAGV2 computes the Generalized Schur factorization of a real 2-by-2 matrix pencil (A,B) where B is upper triangular. This routine computes orthogonal (rotation) matrices given by CSL, SNL and CSR, SNR such that 1) if the pencil (A,B) has two real eigenvalues (include 0/0 or 1/0 types), then [ a11 a12 ] := [ CSL SNL ] [ a11 a12 ] [ CSR -SNR ] [ 0 a22 ] [ -SNL CSL ] [ a21 a22 ] [ SNR CSR ] [ b11 b12 ] := [ CSL SNL ] [ b11 b12 ] [ CSR -SNR ] [ 0 b22 ] [ -SNL CSL ] [ 0 b22 ] [ SNR CSR ], 2) if the pencil (A,B) has a pair of complex conjugate eigenvalues, then [ a11 a12 ] := [ CSL SNL ] [ a11 a12 ] [ CSR -SNR ] [ a21 a22 ] [ -SNL CSL ] [ a21 a22 ] [ SNR CSR ] [ b11 0 ] := [ CSL SNL ] [ b11 b12 ] [ CSR -SNR ] [ 0 b22 ] [ -SNL CSL ] [ 0 b22 ] [ SNR CSR ] where b11 >= b22 > 0. Parameters: A A is REAL array, dimension (LDA, 2) On entry, the 2 x 2 matrix A. On exit, A is overwritten by the ``A-part'' of the generalized Schur form. LDA LDA is INTEGER THe leading dimension of the array A. LDA >= 2. B B is REAL array, dimension (LDB, 2) On entry, the upper triangular 2 x 2 matrix B. On exit, B is overwritten by the ``B-part'' of the generalized Schur form. LDB LDB is INTEGER THe leading dimension of the array B. LDB >= 2. ALPHAR ALPHAR is REAL array, dimension (2) ALPHAI ALPHAI is REAL array, dimension (2) BETA BETA is REAL array, dimension (2) (ALPHAR(k)+i*ALPHAI(k))/BETA(k) are the eigenvalues of the pencil (A,B), k=1,2, i = sqrt(-1). Note that BETA(k) may be zero. CSL CSL is REAL The cosine of the left rotation matrix. SNL SNL is REAL The sine of the left rotation matrix. CSR CSR is REAL The cosine of the right rotation matrix. SNR SNR is REAL The sine of the right rotation matrix. Author: Univ. of Tennessee Univ. of California Berkeley Univ. of Colorado Denver NAG Ltd.
