How to add specific bases at the beginning and ending of all the fasta sequences?
Hi,
I have to add 7 bases of specific nucleotide at the beginning and ending of all the fasta sequences of a file. For example, I have a multi fasta file namely test.fasta as given below
I need to add the following bases CTGATAGTA at the beginning and ending of every fasta sequences respectively.
I have tried the following command line to add bases at the end of fasta file, but it is not serving my purpose,
. For adding bases at the beginning I do not have any idea, However, I tried the following command
, but its adding bases at the fasta header.
Please help me to do the same.
Thank you.
I have got an Perl array like:
@array = (1,2,3,4,5,6,1,2,3,4,1,2,1,2,3,4,5,6,7,8,9...............)
This numeric sequence will be always sequentially increasing, unless it encounters, The beginning of the new sequentially increasing numeric sequence.
SO in this array we get sequentially... (5 Replies)
Hi, I have multiple large files which consist of the below format:
I am trying to write an awk or sed script to remove all occurrences of the 00 record except the first and remove all of the 80 records except the last one.
Any help would be greatly appreciated. (10 Replies)

ABACAS(1) User Commands ABACAS(1)NAME
abacas - Algorithm Based Automatic Contiguation of Assembled Sequences
SYNOPSIS
abacas -r ref -q qs -p prog [OPTIONS]
OR
abacas -r ref -q psf -e
ref reference sequence in a single fasta file
qs contigs in multi-fasta format
rog MUMmer program to use: 'nucmer' or 'promer'
psf pseudomolecule/ordered sequence file in fasta format
OPTIONS
-h print usage
-d use default nucmer/promer parameters
-s int minimum length of exact matching word (nucmer default = 12, promer default = 4)
-m print ordered contigs to file in multifasta format
-b print contigs in bin to file
-N print a pseudomolecule without "N"s
-i int mimimum percent identity [default 40]
-v int mimimum contig coverage [default 40]
-V int minimum contig coverage difference [default 1]
-l int minimum contig length [default 1]
-t run tblastx on contigs that are not mapped
-g string (file name) print uncovered regions (gaps) on reference to file name
-a append contigs in bin to the pseudomolecule
-o prefix output files will have this prefix
-P pick primer sets to close gaps
-f int number of flanking bases on either side of a gap for primer design (default 350)
-R int Run mummer [default 1, use -R 0 to avoid running mummer]
-e Escape contig ordering i.e. go to primer design
-c Reference sequence is circular
DESCRIPTION
ABACAS is intended to rapidly contiguate (align, order, orientate), visualize and design primers to close gaps on shotgun assembled contigs
based on a reference sequence.
ABACAS uses MUMmer to find alignment positions and identify syntenies of assembled contigs against the reference. The output is then pro-
cessed to generate a pseudomolecule taking overlapping contigs and gaps in to account. ABACAS generates a comparision file that can be used
to visualize ordered and oriented contigs in ACT. Synteny is represented by red bars where colour intensity decreases with lower values of
percent identity between comparable blocks. Information on contigs such as the orientation, percent identity, coverage and overlap with
other contigs can also be visualized by loading the outputted feature file on ACT.
