Remove sequences of certain length.

 I need to do the following steps
1. Set pair reads
2. Remove duplicate reads
3. Merge paired reads
4. Error correct and normalise reads
5 remove sequence in each data , which is lower than 151 nucleotides and more than 320 nucleotides.
I have the problem in adding the last step in the workwflow

You can extract sequences of the length you want using the Lengths Graph above the viewer, as shown in the screenshot below:

If you want to automate this in a workflow, you need to do two filtering steps - one to remove the short reads and the other to remove the longer reads.  

The workflow setup would look something like in the screenshot below:

This produces a sequence list with the same names as the input document but containing only sequences between 151 and 320 bp.
