notseq

 

Function

Exclude a set of sequences and write out the remaining ones

Description

When you have a set of sequences (a file of multiple sequences?) and you wish to remove one or more of them from the set, then use notseq.

This program was written for the case where a file containing several sequences is being used as a small database, but some of the sequences are no longer required and must be deleted from the file.

notseq splits the input sequences into those that you wish to keep and those you wish to exclude.

notseq takes a set of sequences as input together with a list of sequence names or accession numbers. It also takes the name of a new file to write the files that you want to keep into, and optionally the name of a file that will contain the files that you want excluded from the set.

notseq then reads in the input sequences. It outputs the ones that match one of the sequence names or acession numbers to the file of excluded sequences, and those that don't match are output to the file of sequences to be kept.

Note that the names of the sequences to be excluded are not standard EMBOSS USAs. Only the name or accession number shoudl be specified, not the database or file that these entries may occur in. These excluded sequence names will be matched against the names of the input sequences to see if there is a match. Wildcarded names may be specified by using '*'s. Any specified names of sequences to be excluded that are not found are simply ignored.

Usage

Here is a sample session with notseq

In this case the excluded sequences (myg_phyca and lgb2_luplu) are not saved to any file:


% notseq 
Exclude a set of sequences and write out the remaining ones
Input (gapped) sequence(s): globins.fasta
Sequence names to exclude: myg_phyca,lgb2_luplu
output sequence(s) [hbb_human.fasta]: mydata.seq

Go to the input files for this example
Go to the output files for this example

Example 2

Here is an example where the sequences to be excluded are saved to another file:


% notseq -junkout hb.seq 
Exclude a set of sequences and write out the remaining ones
Input (gapped) sequence(s): globins.fasta
Sequence names to exclude: hb*
output sequence(s) [hbb_human.fasta]: mydata.seq

Go to the output files for this example

Command line arguments

   Standard (Mandatory) qualifiers:
  [-sequence]          seqall     (Gapped) sequence(s) filename and optional
                                  format, or reference (input USA)
  [-exclude]           string     Enter a list of sequence names or accession
                                  numbers to exclude from the sequences read
                                  in. The excluded sequences will be written
                                  to the file specified in the 'junkout'
                                  parameter. The remainder will be written out
                                  to the file specified in the 'outseq'
                                  parameter.
                                  The list of sequence names can be separated
                                  by either spaces or commas.
                                  The sequence names can be wildcarded.
                                  The sequence names are case independent.
                                  An example of a list of sequences to be
                                  excluded is:

The names (or accession numbers) of the sequences to be excluded can be entered as a file of such names by specifying an '@' followed by the name of the file containing the sequence names. For example: '@names.dat'.

The names or accession numbers of the sequences to be excluded are not standard EMBOSS USAs. Only the ID name or accession number can be specified, you cannot specify the sequences as 'database:ID', 'file:accession', 'format::file', etc.

Output file format

notseq writes normal a sequence file.
