Function:
Cut out a designated section of a single sequence or multiple sequences.


Input:
Upload FASTA format sequences or paste the FASTA format sequences in the window.


Parameters:

①Single sequence interception: input sequence name, start site and end site.

②Multiple sequences interception: upload a txt format section file with three columns: sequence name, start site and end site.

③Extend to the left: number of extended characters from the start site to the left.

④Extend to the right: number of extended characters from the end site to the right.

Note: blank means interception of the full sequence.


Output:

Downloadable FASTA files of intercepted sequences.

Case presentation1:


Input file:example (click to download)


Enter the following four sequences,set:Single segment pattern, set the name of the sequence to seq1, starting position is 3, the end position of 10, to a unit, so the starting position into 2

>seq1
TCATTTAATGAC
>seq2
ATGGC
>seq3
TCACATGATGCCG
>seq4
ATGGAAGC
    

The output of:

>seq1_2_10
CATTTAATG
 

Case presentation2:


Click on the item of tagsb、Multiple sequences interception,Under section file input sequence parameters, format as follows, the model for multiple segments

seq1 1 10
seq2 
seq3 1 10
  

The output of:

   
    >seq1_1_10
    TCATTTAATG
    >seq2
    ATGGC
    >seq3_1_10
