Hi Everyone,
I am new in the world of UNIX and Shell scripting.
I am working with a sequence file that looks like this:

Hi
I have an alignment file (.fasta) with ~80 sequences. They look like this-

Hi,
I am trying to remove lines once a string is found till another string is found including the start string and end string. I want to basically grab all the lines starting with color (closing bracket). PS: The line after the closing bracket for color could be anything (currently 'more').... (1 Reply)

Hello,
I have 10 fasta files with sequenced reads information with read sizes from 15 - 35 . I have combined the reads and collapsed in to unique reads and filtered for sizes 18 - 26 bp long unique reads. Now i wanted to count each unique read appearance in all the fasta files and make a table... (5 Replies)
HI,
I have a Complete genome fasta file and I have list of sub sequence regions
in the format as :
4353..5633
6795..9354
1034..14456
I want a script which can mask these region in a single complete genome fasta file with the alphabet N
kindly help (2 Replies)
I would like to take a fasta file formated like

and use command line perl to move the all sample gt 8 in length to a new file. the result would be

I have to mine the following sequence pattern from a large fasta file namely gene.fasta (contains multiple fasta sequences) along with the flanking sequences of 5 bases at starting position and ending position,

Z represents A, C or G (Except T)
N16 represents any of the four... (3 Replies)
Below are my custom period start and end dates based on a calender, these dates are placed in a file, for each period i need to split into three weeks for each period row, example is given below.
Could you please help out to achieve solution through shell script..

flanks - finding flanking sequences for a variant in a sequence position
SYNOPSIS
flanks --position POS [-p POS ...] [--flanklen INT]
accession | filename
DESCRIPTION
This script allows you to extract a subsequence around a region of interest from an existing sequence. The output if fasta formatted
sequence entry where the header line contains additional information about the location.
OPTIONS
The script takes one unnamed argument which be either a file name in the local file system or a nucleotide sequence accession number.
-p Position uses simple nucleotide sequence feature table
--position notation to define the region of interest, typically a
SNP or microsatellite repeat around which the flanks are
defined.
There can be more than one position option or you can
give a comma separated list to one position option.
The format of a position is:
[id:] int | range | in-between [-]
The optional id is the name you want to call the new
sequence. If it not given in joins running number to the
entry name with an underscore.
The position is either a point (e.g. 234), a range (e.g
250..300) or insertion point between nucleotides
(e.g. 234^235)
If the position is not completely within the source
sequence the output sequence will be truncated and it
will print a warning.
The optional hyphen [-] at the end of the position
indicates that that you want the retrieved sequence to be
in the opposite strand.
-f Defaults to 100. This is the length of the nucleotides
--flanklen sequence retrieved on both sides of the given position.
If the source file does not contain
OUTPUT FORMAT
The output is a fasta formatted entry where the description file contains tag=value pairs for information about where in the original
sequence the subsequence was taken.
The ID of the fasta entry is the name given at the command line joined by hyphen to the filename or accesion of the source sequence. If no
id is given a series of consequtive integers is used.
The tag=value pairs are:
oripos=int
position in the source file
strand=1|-1
strand of the sequence compared to the source sequence
allelepos=int
position of the region of interest in the current entry. The tag is the same as used by dbSNP@NCBI
The sequence highlights the allele variant position by showing it in upper case and rest of the sequence in lower case characters.
EXAMPLE
% flanks ~/seq/ar.embl
>1_/HOME/HEIKKI/SEQ/AR.EMBL oripos=100 strand=1 allelepos=100

TODO
The input files are assumed to be in EMBL format and the sequences are retrieved only from the EMB database. Make this more generic and use
the registry.
