Shell script for changing the accession number of DNA sequences in a FASTA file
Hi,
I am having a file of dna sequences in fasta format which look like this:
>admin_1_45
atatagcaga
>admin_1_46
atatagcagaatatatat
with many such thousands of sequences in a single file. I want to the replace the accession Id "admin_1_45" similarly in following sequences to "mydesired_name_45" replacing serially 46,47, 48 with my desired name as static next to each of the > symbol.
kindly help me with the script

TFBS::PatternGen::SimplePFM(3pm) User Contributed Perl Documentation TFBS::PatternGen::SimplePFM(3pm)
NAME
TFBS::PatternGen::SimplePFM - a simple position frequency matrix factory
SYNOPSIS
my @sequences = qw( AAGCCT AGGCAT AAGCCT
AAGCCT AGGCAT AGGCCT
AGGCAT AGGTTT AGGCAT
AGGCCT AGGCCT );
my $patterngen =
TFBS::PatternGen::SimplePFM->new(-seq_list=>@sequences);
my $pfm = $patterngen->pattern(); # $pfm is now a TFBS::Matrix::PFM object
DESCRIPTION
TFBS::PatternGen::SimplePFM generates a position frequency matrix from a set of nucleotide sequences of equal length, The sequences can be
passed either as strings, as Bio::Seq objects or as a fasta file.
This pattern generator always creates only one pattern from a given set of sequences.
new
Title : new
Usage : my $db = TFBS::PatternGen::SimplePFM->new(%args);
Function: the constructor for the TFBS::PatternGen::SimplePFM
object
Returns : a TFBS::PatternGen::SimplePFM obkect
Args : This method takes named arguments;
you must specify one of the following
-seq_list # a reference to an array of strings
# and/or Bio::Seq objects
# or
-seq_stream # A Bio::SeqIO object
# or
-seq_file # the name of the fasta file containing
# all the sequences
pattern
all_patterns
patternSet
The three above methods are used fro the retrieval of patterns, and are common to all TFBS::PatternGen::* classes. Please see
TFBS::PatternGen for details.
