67
68 **Example 1**
69
70 Trimming this dataset::
71
72 1234567890
73 abcdefghijk
74
75 by setting **Trim from the beginning to this position** to *2* and **Remove everything from this position to the end** to *6* will produce::
76
77 23456
78 bcdef

80 -----
81
82 **Example 2**
83
84 Trimming column 2 of this dataset::
85
86 abcde 12345 fghij 67890
87 fghij 67890 abcde 12345
88
89 by setting **Trim content of this column only** to *2*, **Trim from the beginning to this position** to *2*, and **Remove everything from this position to the end** to *4* will produce::

96 **Trimming FASTQ datasets**
97
98 This tool can be used to trim sequences and quality strings in fastq datasets. This is done by selected *Yes* from the **Is input dataset in fastq format?** dropdown. If set to *Yes*, the tool will skip all even numbered lines (see warning below). For example, trimming last 5 bases of this dataset::

114 .. class:: warningmark
115
116 **WARNING:** This tool will only work on properly formatted fastq datasets where (1) each read and quality string occupy one line and (2) '@' (read header) and "+" (quality header) lines are evenly numbered like in the above example.
