**What it does**

This tool trims (cut bases from) sequences in a FASTA/Q file.



Input Fasta file (with 36 bases in each sequences)::


Trimming with First=1 and Last=21, we get a FASTA file with 21 bases in each sequences (starting from the first base)::


Trimming with First=6 and Last=10, will generate a FASTA file with 5 bases (bases 6,7,8,9,10) in each sequences::



This tool is based on `FASTX-toolkit`__ by Assaf Gordon.
