45 **What it does**
|
|
46
|
|
47 This tool computes an expression for every row of a dataset and appends the result as a new column (field).
|
|
48
|
|
49 - Columns are referenced with **c** and a **number**. For example, **c1** refers to the first column of a tab-delimited file
|
|
50
|
|
51 - **c3-c2** will add a length column to the dataset if **c2** and **c3** are start and end position
|
|
52
|
|
53 -----

|
|
55 **Example**
|
|
56
|
|
57 If this is your input::
|
|
58
|
|
59 chr1 151077881 151077918 2 200 -
|
|
60 chr1 151081985 151082078 3 500 +
|
|
61
|
|
62 computing "c4*c5" will produce::
|
|
63
|
|
64 chr1 151077881 151077918 2 200 - 400.0
|
|
65 chr1 151081985 151082078 3 500 + 1500.0
|
|
66
|
|
67 if, at the same time, "Round result?" is set to **YES** results will look like this::
|
|
68
|
|
69 chr1 151077881 151077918 2 200 - 400
|
|
70 chr1 151081985 151082078 3 500 + 1500
|
|
71
|
|
72 You can also use this tool to evaluate expressions. For example, computing "c3>=c2" for Input will result in the following::
|
|
73
|
|
74 chr1 151077881 151077918 2 200 - True
|
|
75 chr1 151081985 151082078 3 500 + True
|
|
76
|
|
77 or computing "type(c2)==type('') for Input will return::
|
|
78
|
|
79 chr1 151077881 151077918 2 200 - False
|
|
80 chr1 151081985 151082078 3 500 + False
